Thank you to all who visited us at Booth C1452 in the Building Automation and Controls section of the AHR Expo this year in Las Vegas, Nevada! We enjoyed seeing both new and familar faces! The world's largest HVACR event was anything but boring and we think the 60,000 attendees would have to agree.

The first and most important consideration is pressure. A number of questions must be answered to ensure the correct transducer is selected. What is the pressure range that the transducer will measure? What is the maximum pressure the transducer will encounter? What is the potential for over pressure in the system?

Unidirectional pressure transducers measure between zero and a positive pressure. The diaphragm of the sensor should only move in one direction and will produce a positive voltage or milliamp output.

Pressure transducers today are more rugged and reliable than ever. Made of stainless steel construction, they provide abundant overpressure protection, improved total error band, and offer negligible orientation and vibration effects. They are ideal for long-term use even in harsh environments of extreme temperature, humidity, and vibration.

The accuracy of differential pressure transducers has greatly improved to provide better solutions for demanding applications. This article discusses why accuracy is an important consideration when selecting a pressure transducer for low-differential, critical pressure applications.

Setra’s capacitive pressure transducers are expertly designed adaptations of a simple, durable and fundamentally stable device...the electrical capacitor. In a typical Setra configuration, a compact housing contains two closely spaced, parallel, electrically isolated metallic surfaces, one of which is essentially a diaphragm capable of slight flexing under pressure.

Newly Added Restricted Products Under RoHS2 Affects Manufacturing
In 2013, RoHS2 was created by the European Union legislation, nearly a decade after the original RoHS (Restriction of Hazardous Substances Directive) was implemented. RoHS2 is merely an evolution of RoHS1 that provides greater clarity on the legal scope of products that should adhere to the hazardous material guidelines. The combination of

Recently, the Department of Energy (DOE) released a new requirement that goes into effect on Jan. 1st, 2017 as part of the "Energy Conservation Program: Test Procedures for Central Conditioners & Heat Pumps.” All manufacturers of heating and cooling systems need to ensure that the AHR units they manufacture for residential and small commercial applications meet this new standard.

Total Error Band (TEB) is a measurement of worst case error; it is the most comprehensive and concise measurement of a sensors true accuracy over a compensated temperature range. TEB is extremely important to know when trying to determine how well a sensor will work within a particular design system. By calculating TEB you'll be able to understand the different possibilities for error. Formulating TEB can be tricky if you don't have the right inputs readily available.
