Companies whose product objectives include reducing costs or waste, more reliable equipment management; improved physical asset control or greater situational awareness should investigate the variety of capabilities wireless sensor systems can provide. In addition to the potential savings in energy, there are likely many additional cash benefits to be found.

With 22% of the globe’s energy consumption, the US is the largest energy consumer and lowest energy producer of any developed economy in the world. The result? It is the most CO2 intensive nation in the world with a daily consumption of 6 gallons of oil per person per day or 19 tons of carbon dioxide per capita annually. This is 80% higher than Europe and 94% higher than Japan.

The greatest sources of US energy expenditure are:

• Industrial Energy 35% (chemicals, steel, processing etc)

• Road transportation is 25%

• Residential energy consumption 21%

• Commercial buildings 16%

Over the next decade, those sectors of the economy driven by consumer demand are the ones which will most rapidly increase greenhouse gases – buildings and houses.

The good news is that there are multiple opportunities to improve upon these areas. For example, the demand for energy could be reduced by 25 to 30% through a series of low cost, high return steps:

• Monitor & control of energy consumption specifically heating and cooling in homes and buildings – Smart Grid

• Replacement of incandescent bulbs with compact florescent lighting

• Equipment replacement, choosing high-efficiency water heaters and Energy StarTM appliances when it’s time for new These seemingly small steps save energy and reward investment with a rapid payback of less than 2 years, although many are immediate and some actually pay for themselves instantaneously.

In fact, according to the McKinsey Report “Reducing U.S. Greenhouse Gas Emissions: How Much What Cost” 40% of the total options for reducing greenhouse gases do not cost, rather releases money into the economy.

As the recognition not only of the costs of global warming, but also the savings to be realized with replacement and upgrading, become apparent, opportunities abound! There are numerous initiatives and programs supporting environmentally friendly products and solutions which continue to unfold at a breakneck pace. These initiatives are for products designed to be manufactured using greener processes and handled responsibly at the end of their life cycle as well as those specifically designed to aid industries and individuals in reducing their carbon footprint. Products such as Western Digital’s GreenPower hard drives and Seimens hybrid drive system for buses reduce energy consumption and CO2 emissions up to 40 percent. Both were developed under green initiatives and are taking their industries by storm.

Green Engineering, what is it?

The Climate Control Bill introduced by Representatives Edward Markey (D-Mass.) & Henry Waxman (D-Calif.) in May of 2009 introduced the most recent version of the American Clean Energy & Security Act and aims to reduce greenhouse gas emissions by 17% below 2005 levels by the year 2020. It would distribute up to 85 percent of pollution permits in a proposed cap-and-trade program.

The Carrot & Stick

Cash & Energy Savings Using Wireless Sensor Networks

Industries everywhere are finding ways to save not only on energy and it’s costs but through the use of wireless networks, in numerous other ways too.

According to Oak Ridge National Laboratories, through the use of wireless sensor networks, savings on energy for motors used in industrial processes could improve efficiency by 20%, resulting in significant cost savings. Wayne Manges said: “With electric motor-driven systems accounting for nearly one-fourth of all electricity consumption in the United States, the potential for savings is huge.”

The Department of Energy’s Industrial Technologies Program works with US industry to improve environmental performance and energy efficiency. The ITP is distributing 15 million to support R&D specifically to improve energy efficiency in industrial processes. Already a number of new wireless sensor products are being developed together with the Department of Energy.

Cost savings with wireless systems are recognized in multiple areas including materials and labor where the cost of running wire in plants ranges between $155 and $3,700 per foot. The typical payback for wired systems is 24 months and less than a quarter of that for a wireless equivalent, only six months. Add in the on-going energy savings and the return on investment decision is very clear.

In a large number of industries, companies are recasting their product lines to implement wireless technologies. “We can’t think of any segment of the industry that isn’t going to be impacted by this,” states Honeywell’s CTO Dan Shiflin.

Wireless sensor networks of all varieties are exploding into our world. There is a massive amount of research & development, from academia to start-ups, pushing to create proverbial “better-faster-cheaper” products. A growing number of products are based on an emerging specification “ZigBee”. A majority of utility companies that have settled on a standard have identified ZigBee as their preference due in main to its inherent security capabilities. Real-time data from wireless sensors networks will enable companies to achieve greater productivity and efficiency by continually improving their processes.

Named BP International’s first Director of Technology & Sensory Networks, for the oil company’s Technology Office, Ken Douglas said “You don’t ask people ‘How would you use ZigBee?’ Because they don’t know, but if you ask them: ‘How would you use information that you can now access for the first time?’ They have to think about it for a bit, but then the ideas just starting pouring out.”

In addition to the benefits of ZigBee’s security layers, the mesh network is highly reliable, flexible and can connect a variety of sensors simultaneously including protocols such as OPC, Modbus and HART.

The technologies for green engineering are not only cost effective, if done right, they are cash positive. When it comes to the design and development of products that are energy efficient and eco-friendly, as well as cost effective, wireless sensor networks make “better faster cheaper” energy saving products. Electronic designs using Zigbee products are making home sensors and energy saving devices a reality.It is less expensive when you get smarter, simpler products with better resource utilization while conserving precious resources.

Engineering…great profession…

“Engineering … it is a great profession. There is the fascination of watching a figment of the imagination emerge through the aid of science to a plan on paper. Then it moves to realization in stone or metal or energy. Then it brings jobs and homes to men. Then it elevates the standards of living and adds to the comforts of life. That is the engineer’s high privilege.”

Uninterruptible power supplies (UPS) are sophisticated, microprocessor-controlled systems, capable of providing a range of alarm notifications and real-time monitoring information at local, network and remote site locations.

This is important because it offers peace of mind and negates the need for ‘warden-type’ manual inspection of power protection equipment. However, monitoring for alarm conditions is required. The beauty of today’s UPS equipment is that it can now be carried out at one location, either centrally in-house or off-site at a specialist UPS monitoring provider. Many leading power protection manufacturers, such as Riello UPS, provide this type of service. It often means an engineer can be on-site and have equipment repaired, checked and running before the client is even aware of a problem.

The decision not to outsource uninterruptible power supply monitoring must be reinforced by the provision of dedicated monitoring personnel in-house whose responsibility it is to monitor and respond to UPS alarms. Failure to act in a timely and appropriate manner will significantly reduce system resilience. Typical examples include failure to notice that a UPS is operating in bypass mode or that there is a failed battery in a battery string (note: a UPS battery string is only as strong as its weakest battery).

The advent of Html capability in the software arena has enabled modern UPS manufacturers to integrate sophisticated onsite and remote monitoring capability within their hardware. In fact, modern systems enable remote 24/7 monitoring (either by the client or at the manufacturer’s facility) of all critical UPS, generator, air-conditioning and fire suppression equipment. As well as alerting system managers to problems as they arise, integration of monitoring functions into existing infrastructures gives businesses valuable early warning of impending power and other equipment failures that actively increases profitable uptime.

Most UPS are available with software packages that monitor mains voltage, UPS load and battery charge as standard, as well as proprietary monitoring and control software, which allows remote interrogation of UPS logs and operating parameters to help diagnose alarms and faults. When instructed to do so, UPS software can remotely perform automated and controlled shutdown of valuable equipment – ensuring hardware protection while freeing personnel for other tasks during power continuity incidents.

Types of alarms include:

Audible Alarms: audible signals are generated from within the UPS or a connected remote status panel and may be coded, using varying lengths of sound, to indicate specific alarm conditions. Audible alarm signals will remain ‘on’ until the condition is rectified or the alarm is acknowledged and silenced.

Visual Alarms: light Emitting Diodes (LEDs) provide a basic form of visual alarm notification. They may be single or multi-coloured and indicate the status of the UPS by employing one of three modes: on, flashing or off.

Some UPS utilise Liquid Crystal Display (LCD) with push-button controls to provide a slightly higher level of visual alarm capability. In this case, the user can scroll through a menu of information (measurements and logs).

The most sophisticated level of visual display is a full front-panel graphic-type, which typically consists of multi-character back-lit lines that display information in alpha, numeric and symbolic formats, either as text, alarm codes, graphics or a combination thereof.

Remote communication can utilise one of several protocols to provide data-exchange between an application and its UPS: serial connection (including RS-232), Simple Network Management Protocol (SNMP), MODBUS/JBUS or Profibus.

A range of UPS monitoring packages are available from UPS suppliers – from simple installation software designed to run on laptops, PCs and PDAs to more sophisticated monitoring and control software that runs on an enterprise server (whether Microsoft Windows, UNIX, Mac, HP and many others) and provides a host of information from UPS operating conditions to WAP availability.

There are two common approaches to monitoring and control by uninterruptible power supply manufacturers: centralised and decentralised. Centralised is where a specified server is used to control the orderly shutdown of the mixed platform network. Decentralised is where each individual server or PC runs its own copy of the monitoring software and controls its own shutdown procedure. The centralised approach is the most straightforward and least expensive to install but it can introduce a single-point-of-failure into the system. Should the control server hang and fail to shutdown the rest of the routine will be disrupted leading to potential data loss and a system-wide crash. With the decentralised approach, if one server or PC fails to shut down, the problem is isolated, thus achieving a higher level of system resilience.

The human instinct upon hearing or seeing an alarm is often to ignore it but planning how to monitor uninterruptible power supplies and associated alarm signals, and conceptualising appropriate responses, is an important aspect of a power continuity plan. If you want to go into it in more detail, there is a whole chapter devoted to it in The Power Protection Guide.

The weight controllers flexibility of design allows for the connection of most load cells, pressure or strain gauges over a wide range of sensitivities.

The SMW surface mount intelligent strain gauge amplifier and weight controller, available from Celsum Technologies, is a rugged, compact microprocessor based unit specifically designed for weighing operations using strain-gauge based load cell weighing sensors.

With an eight-digit 12.7mm LCD, and housed in a light grey ABS case, the SMW is sealed to IP65 standard to meet most environmental conditions, or as a DIN rail mounting module with a separate stainless steel panel mounting display and keypad.

The strain bridge circuit has an excitation voltage of 10V with a capacity of 160mA, sufficient to handle up to six 350ohm load cells in parallel.

The working units may be set as engineering units, and communication with intelligent hosts is possible via the ASCII, Modbus and Mantrabus protocol options.

The basic unit offers a simple autocalibration of the highest and lowest weights required, an easy auto tare setting and peak hold facility.

A password facility gives protection to setup parameters.

DC analogue outputs of 4-20mA and 0-10V are standard with full scaling over any desired range and the ability to invert these outputs if required.

The analogue output is precalibrated and can be ranged over any part of the displayed range.

Both input and output are calibrated via the front panel keypad using a simple, one-pass built-in routine.

Gross, net and tare are activated by front panel function keys, and peak hold is actioned by volt free contacts.

Gain sensitivity is selectable via DIL switches between 0.5 and 200mV/V.

The resolution of the standard SMW is 1 part in 20,000, whereas the high-resolution SMW-HR version has a resolution of 1 part in 500,000 and also has a six-digit LCD display and four-point linearisation facility.

Several “plug in” options are available.

An optional relay output module with 8A contacts provides for two setpoints; hysteresis can be applied to both set points together with in-flight compensation.

Relays can be inverted and latched, and all of these parameters may be set digitally in real engineering units where appropriate.

Both relay and analogue outputs have a high level of isolation.

Optional communications modules provide for 20mA noise-immune current loop, RS232 or RS485 connections to a PC, PLC or main frame.

This allows for the input variable to be viewed and any setup parameters changed.

Multiple 20mA SMWs can be connected via an IF25 current loop to RS232 interface which, when included, allows for an expansion of up to 250 SMWs.

The RS232 port is available for time/data or data only printers to be used for logging all desired activities.

Baud speeds between 300 and 19,200 are selectable.

Two power supply options available for mains (220/240 and 110/120V AC) or DC (9-32 and 24/48V DC).

Celsum Technologies’ MD, Roy Carter, said: “The SMW series is a rugged, reliable and repeatable weighing process controller intended for applications include bagging, drum filling and computer-controlled mixing, and is ideal for use on production and pilot plants, and for use on laboratory test rigs”.

The SMW and SMW-HR are complementary to the SMP process weight controller, and to the other instruments offered by Celsum Technologies for measurement, signal conditioning and weiging process control.

It may sound like the mantra of some fashion icon, but unlike the fickle fashion business, where accessories merely enhance the look of an outfit, uninterruptible power supply accessories play a more functional role in the overall power protection strategy. There to enhance the workability, functionality and reliability of the UPS system, accessories also play a vital role in adding value and overall resilience. UPS accessories include software, adapters, sensors, cable converters, interface panels and bypasses, all purposely designed to work alongside UPS and for implementation in power protection applications.

Software: most reputable uninterruptible power supply manufacturers provide user-friendly management and monitoring software. UPS software displays real-time information in the form of bar charts and values explaining critical data such as mains voltage, UPS load and battery charge percentage.

UPS software enables remote interrogation of logs and operating parameters to help diagnose alarms and potential fault conditions. When instructed, it performs an automated safe power down of protected loads (PCs and file severs, for example) to safeguard them against damaging and costly system crashes.

Adapters: network Management Protocol (SNMP) adapters, USB converters, duplexers and protocol converters expand the communications capabilities of uninterruptible power supplies and provide ease of management across networks and multi-operating platforms.

These devices are usually bespoke-designed for specific customer projects.

Network agents (such as Riello UPS’s NetMan) allows UPS management across a LAN using any of the main network communication protocols – TCP/IP, HTTP and network interface (SNMP). Network agent-enabled uninterruptible power supplies integrate easily into medium and large sized networks and provide reliable communication between the UPS and management systems that are employed therein.

Cable and Protocol/Converters: protocol converters (such as Riello UPS’s MultiCOM) may be used to monitor the UPS using the MODBUS/JBUS protocol on RS485 or RS232 serial lines. It will also manage a second, independent RS232 serial line that can be used to connect other devices such as the network agent or PC running the uninterruptible power supply management and monitoring software.

The device integrates the UPS with control systems and offers complete configurability of the input and output signals. The RS232-USB converter allows uninterruptible power supplies without a USB port to connect to Macintosh, Windows and Linux PCs (provided they have a USB port).

Sensors: uninterruptible power supplies, and UPS batteries in particular, are susceptible to changes in the environment so sensors that keep a check on temperature and humidity are advisable to be used in a power protection system. UPS batteries, in particular, must be stabilised at an ambient temperature of 21-25 degrees centigrade. Even so much as one degree above or below this threshold can seriously diminish the design life of UPS batteries.

Panels: the panels that sit on the front of the uninterruptible power supply unit and act as the operator interface need to be clear, visual, easy to operate and understand plus robust enough to withstand their environment (whether heavy industrial or dynamic IT sites).

In addition, some manufacturers offer a remote monitoring panel designed to provide a detailed overview of the UPS to which it is connected. This panel can provide a range of useful operating information (in a variety of languages – depending upon operator preference) including specific UPS input and output voltage and frequency values and status information on the UPS battery set.

Riello UPS’s MultiPanel, for example, has three independent serial ports – one for UPS monitoring using the MODBUS/JBUS protocol (either an RS485 or RS232 serial line) and others designed for use with UPS accessories such as network agents and UPS monitoring and control software.

When selecting a panel it is advisable to choose one that is compatible with most building management systems, and that has a communications flow LED status indicator and the capability for firmware upgrade via one of its serial ports.

Bypasses: in this day-and-age of continuous uptime and 24/7 operating environments, an uninterruptible power supply maintenance bypass is a must. It allows a UPS unit to be powered down for maintenance without disruption to the load and is typically installed with on-line power systems from 700VA to 800kVA. Many bypasses available from reputable UPS manufactures are ‘plug and play’ with a range of socket configurations, and are usually available in wall mounting and 19″ rackmount formats so as to be able to be sited in server racks alongside computer loads. An additional safety feature is an automatic transfer should the output of the UPS fail due to overload, system fault or accidental disconnection.

So, with uninterruptible power supplies it is wise to accessorise but select carefully. Compatibility is key. Choose accessories that are most closely related to the actual UPS system itself. Sourcing from the same manufacturer is recommended.

In manufacturing facilities and factory processes, the data logger is now in everyday use for measurement and data recording of critical parameters.

Main data logger applications include:

A temperature data logger is also often used to record temperature in drying processes in food production and curing of smoked foods.

Use of data logger units in brick works, kilns and ovens for temperature profiling. Often here the data logger will be fitted inside a thermal barrier to protect from heat damage

In factory processes a data logger with digital and pulse inputs can be used to record machine run time, down time, and throughput of product which can later be used for statistical analysis of production efficiency.

A data logger with appropriate sensors can also be used to measure compressed air usage, product levels in tanks, and system voltages.

Selecting the right Data Logger

When selecting the most appropriate data logger for a process measurement job a few key factors should be considered:

Often a data logger needs to be fitted in part of a process plant far from the main production area. In this case a data logger with integral radio modem or network capability will be easier to interface with the main plant data logger system

Many factory environments are ether dusty, dirty, or have high levels of humidity so the data logger should be well sealed, if possible to IP68. In some processes the ambient temperature can also be very high and many data logger types now will operate up to 85 degrees C.

Pharmaceutical plants, refineries and oil rigs also have many data logger applications in process measurement. A data logger used in these environments not only needs to be rugged and weatherproof, but also intrinsically safe. An intrinsically safe data logger is by design incapable of generating enough energy to be a source of ignition. At the present time only a few data logger types are available with intrinsic safety, mostly for measurement of temperature, humidity and pressure.

In through process applications very little space is available for additional devices in the production line so the data logger should be small and light weight. In addition these processes may produce high temperatures and humidity so the selected data logger should be waterproof and have a high operating temperature.

Many manufacturing processes now use sensors or PLC’s with serial MODBUS outputs. Here a traditional data logger with analogue inputs is useless. However in the last couple of years data logger models with MODBUS inputs have become available to meet this need. Utilizing the MODBUS system additional input modules can be added to this type of data logger to greatly increase the channel I/O count and also network the data logger input and outputs across a manufacturing plant.

With increasing levels of automation and the reduction of man power in manufacturing plants and processes data logger technology will continue to play a vital and expanding role in industrial measurement, data acquisition and statistical analysis.

Lobel’s Transmitter: sixth generation AST3 weight transmitter is available in a package that weighs less than the mains transformer of the original Scale-O-Scope 25 years ago

In 1973, Bofors Electronic Transmitter(as Nobel Systems was then called), produced the world’s first microprocessor- controlled weight controller and terminal, the Scale-O-Scope.

Over 25 years after this milestone in the history of electronic load cells weighing and force measurement, Nobel’s sixth generation AST3 weight transmitter is available in a package that weighs less than the mains transformer of the original Scale-O-Scope.

The ground-breaking Scale-O-Scope was designed and manufactured by Bofors Electronics in conjunction with its patented KIS dual shear beam load cells for weighing and stock control in the meat processing industry.

The weight controller’s ability to process input and output data, communicate with other Scale-O-Scope terminals, printers and with main frame computers led to a great increase in efficiency, and typically a doubling of profitability in the plants in which they were installed.

The Scale-O-Scope weighed 30kg, used an Intel 4040 4-bit processor with 4k memory, and featured 16-bit A/D conversion, a resolution of 1 in 30,000, and a communication speed of 300 baud.

It boasted digital scaling and set up, keyboard input and a dot matrix digital weighing display with alpha-numeric presentation of weight and data.

The trend since then has seen the extensive use of microprocessor power to give greater flexibility, higher resolution and accuracy, faster speed, easier setting up, smaller size and lower cost.

More than twenty-five years on from the Scale-O-Scope, E-2-TAD weighs in at 3kg, has three microprocessors, a resolution of one in half a million and communicates with RS232, 422 or 423 at 9600 baud .

It is CE EMC compliant, and has OIML (weights and measures) certification for accuracy class III for 10,000 divisions.

Now, the sixth generation AST3 goes one stage better, with an internal resolution of 1 in 8 million (23 bit) using a patented Sigma-Delta A/D conversion technique and communicates on RS485 at 115k baud using modbus protocol.

Analogue outputs of 0-10V, 0-2mA or 4-20mA are standard.

Communication speed is 380 times greater than the original Scale-O-Scope and resolution 260 times greater.

There are no potentiometer adjustments – all scaling is carried out and stored digitally and can be carried out via the front panel keypad or downloaded via the serial port using windows-based software.

Filtering can be pre-programmed to suit the dynamics of the application and is “adaptive” – that is, it has a wide bandwidth and fast response for large weight changes and shuts itself down to a narrow bandwidth for small changes.

The AST3 can also be connected via a modem to allow remote diagnostics and maintenance of the weighing system.

The unit is fully CE compliant to meet the latest EMC and low-voltage directives.

All this comes complete with a digital display in a DIN rail-mounted package that weighs less than 0.5kg.

Small is definitely beautiful – the new AST3 weighs approximately 1/60th of the original Scale-O-Scope of 1973.

This is exemplified by Nobel’s microprocessor-based weighing instruments, the E-2-TAD digital weighing controller and the most recent AST3 weight transmitter.
