DCS POSITAL Explosion Proof Rotary Encoders 1 400

POSITAL’s explosion-proof IXARC rotary encoders have been certified to comply with ATEX/IECEx directives for Category 3 electrical products. These devices are suitable for use in Zone 2 and Zone 22 conditions (potential exposure to hazardous levels of explosive gases and flammable dust) and are ideal for oil and gas installations, chemical plants, woodworking operations, and grain handling facilities. Certification documents cover multiple encoder configurations and were issued by an organization with special competency in ATEX and IECEx testing and certification. 

POSITAL’s ATEX/IECEx-certified series of encoders feature aluminum or stainless-steel housings designed to eliminate electrical hot-spots or sparking that could ignite an explosion. These encoders are available in both incremental and absolute variants and are offered with optical or magnetic measurement systems. Optical encoders are suited for high-precision applications, delivering up to 16-bit resolution and excellent dynamic response. Magnetic variants offer similar resolution and feature compact, rugged designs that makes them highly versatile and suitable for harsh environments.

For many magnetic encoders, some operating characteristics can be modified through software updates with no need for mechanical changes. For example, for programmable incremental encoders, resolution can set anywhere between 1 and 16,384 PPR (pulses per revolution) by selecting the appropriate software parameters. For absolute encoders, both magnetic and optical variants are available in multiturn versions with battery-free rotation-counter systems. There is no need to test and replace backup batteries, drastically reducing maintenance requirements. 

Like other members of the IXARC encoder family, ATEX/IECEx certified models can be ordered with a wide range of mounting flange designs and shaft configurations. They are available with connectors (M12 etc.) or attached cables and support a variety of communications interfaces, including incremental, analog, SSI, Profibus, ProfiNet, CANopen, DeviceNet, EtherCAT, EtherNET IP, Modbus RTU, J1939, and Modbus TCP. This wide range of configuration options makes it possible to select an encoder configuration that will be easy to integrate into almost any machine or system.

Finding the right IXARC sensor for a particular application is straightforward. Go to www.posital.com to find a powerful product finder tool that enables a customer to specify the product features required for each application and then quickly zero in on the best available products.

DCS Siemens SIRIUS Controls Ensures Cold Beer 1 400

Breweries are known for transforming malt, hops, and yeast into beer in gleaming brewing kettles and large fermentation tanks linked by numerous pipes.

Over the centuries, the equipment for mashing, lautering, boiling, and fermenting beer according to carefully guarded recipes has been steadily perfected.

 

The chiller is the heart of the brewery

One of the most important parts of the brewery, and perhaps the least visible, is the chiller. The fermentation temperature of the beer is crucial, which means that the heat generated by the yeast fermentation must be carefully controlled by the chiller.

If the beer ferments at too high a temperature, the yeast can produce a variety of undesirable aromas that ruin the beer.

According to Justin Thomas, President of G&D Chillers, based in Oregon

"The chiller is the heart of the brewery. Owners invest not only a lot of money in the brewery and brewing equipment, but also a great deal of time in the production of beer. But if the chiller fails, all that goes out the window."

Partnerships to keep pace with growth

Thomas says that growth at G&D Chillers has been exponential over the past 15 years. To continue this rate of success, the company had to look for new ways to meet customer demands for reliable, state-of-the-art chiller options.

For example, G&D Chillers recently teamed up with Siemens and the global distribution and supply chain solutions company WESCO to meet these needs and stay ahead of the competition. "We're still a small manufacturing company, but big enough to produce some technically advanced equipment," says Thomas. "We've always been service-oriented and always stood by our equipment, no matter what the problem. We get the same kind of support and service from Siemens that we give to our own customers."
