Many of the following technical specifications appear on datasheets for pressure transducers and similar devices. Here we review their technical definitions and relationships.

Root Sum Squares (RSS): accuracy of a pressure transducer is calculated by taking the square root of non-linearity + hysteresis + non-repeatability.

Popular Types of Current Sensors

Current Shunts

Current Shunts are low value resistors that are inserted into a circuit. The shunt provides terminals to connects the sensed current and voltage monitoring terminals. The commercially available shunts have sensed current ranges from less than 1A to several hundred amps.

Technology Trends at the 2015 AHR Expo

A week ago the 2015 AHR Expo kicked off at McCormick Place in Chicago. Not only were there 8% more exhibitors than last year's expo, but an extensive number of new HVACR products and technologies were featured at various booths. Setra was among these companies using the AHR Expo as a platform to launch the latest products in HVACR.

Here's What You Missed at the 2015 AHR Expo

Thank you to all who visited us at Booth 3823 in the Building Automation section of the AHR Expo. We enjoyed seeing both new and familar faces! The world's largest HVACR event was anything but boring. With 8% more exhibitors than last year and approximately 62,000 attendees, AHR was a huge success.

The 2015 International Consumer Electronics Show

For four days, Las Vegas was home to some of the most innovative technology products ever seen. This year's International CES kicked off on January 6th, and had not only the most technologically advanced products featured on the show floor, but also gave attendees the opportunity to listen to presentations given by some of the brightest in the industry.

Three Part Blog Series: Why Building Humidity is Important

Selecting a Proper Humidity Sensor

Throughout this three part blog series, real world scenarios, health & safety concerns, cost savings, mold prevention, and industry best practices for proper sensor selection relating to building humidity levels will be reviewed and analyzed. Part 3 examines the best practices for selecting the right humidity sensor for wall mount, duct mount, or outside air along tips for field replacement.

Industrial pressure transducers are used in a wide variety of applications ranging from HVAC/R compressors, refrigeration and variable speed pumps to hydraulic pressure, oil and water. A transducer can be used anywhere there's a pipeline or chamber, its function is to sense and convert pressures into a proportional electrical output signal that is transmitted to monitoring or control system.

GIS (Geographic Information Systems) believe it or not will make just about any HVAC professional's job easier. Aerial photography became extremely useful to contractors when progress ofhttp://blog.setra.com/gis-can-make-hvac-jobs-easier/2014/10/02 projects could be shown through pictures. Eventually other job functions caught onto this resource that had been available for years.
