Visit Us at the Process Heating & Cooling Show!

It’s here! The Process Heating & Cooling Show kicks off today at the Donald E. Stephens Convention Center in Rosemont, IL. Be sure to stop by booth 313 to meet the Dwyer Instruments and Omega Engineering teams, and learn how we can help with your next process automation project. 

We will have a flow bench at the booth where you can see our products in action including the latest temperature, pressure, flow, and industrial internet of things (IIoT) technologies. Continue reading “Visit Us at the Process Heating & Cooling Show!”

Differential Pressure Switch/Gage within Semiconductor Fabs

semiconductor facility building outside

In simple terms, a semiconductor transistor is a part with specific electronic properties that allow it to serve as a component in microchips and modern electronics like phones, laptops, and more. As these components are small and require precise manufacturing methods, there are facilities dedicated to their manufacture.

These facilities consist of several levels including air handlers and scrubbers for exhaust, HEPA room, fab cleanroom, and subfab areas. The control of differential pressure within the facility is essential for the safety of both equipment and personnel. Continue reading “Differential Pressure Switch/Gage within Semiconductor Fabs”

Series IDPT: Built for Compliance

The HVACR industry is evolving to create more energy efficient and sustainable ways to cool our homes and commercial buildings using eco-friendly refrigerants that are less damaging to the environment, but significantly more flammable than their predecessors. The UL standard 60335 aims to balance these greener refrigerants while still maintaining occupancy safety as it applies to “packaged air conditioners and heat pumps; partial units; liquid chillers and hydronic fan coil units; hot water heat pumps; dehumidifiers; supplemental heaters and equipment with flammable refrigerants1.”

With this standard there are significant regulations put onto the plastics used in air handlers to meet certain burn and smoke criteria, as tested and approved by the UL Yellowcard. Some air handling equipment manufacturers are attempting to meet this specification for pressure transmitters and sensors by mounting pressure transmitters that are typically made of plastic in a metal enclosure or mounting them outside of the plenum spaces.  Continue reading “Series IDPT: Built for Compliance”

Airports Use Dwyer Building Automation System Products

Tapping your foot anxiously, you glance at your airline ticket and the terminal noted on it. The flight will be boarding in a few minutes. As you look around, there are several other people waiting for this flight; it seems the plane is fully booked. You close your eyes and breathe in deeply, calming your nerves. The air seems fresh, not stagnant, despite the large number of people around you. There are no empty seats in the area, so you carefully find a window to lean against as you watch the airplanes of other terminals and wait for your own.

Airports must provide a controlled environment for their visitors, while allowing scheduled maintenance within a building that is operational 24/7. Additionally, they must offer a high level of security for their passengers, all while simultaneously moving those travelers and their luggage rapidly through the building, in a finite amount of time.

Generally, airports are large complex buildings divided into numerous areas, with a number of smaller units located within them. Building automation systems (BAS) are used within airports to monitor and control sensors for things like filters, temperature, air flow, and building energy usage.

Airport automation, put simply, is needed to help ensure safety for world travelers and efficiency for those who make it possible. When an airport’s BAS is functioning properly, travelers can focus on the tasks at hand while everything runs in the background to keep them safe.
