Sensata Technologies Introduces EMI-Protected Sensors

January 31, 2007

New case-isolated pressure sensors are designed for use in commercial HVAC/R systems, where high levels of electrical noise limit integration of electronic pressure sensors.


ATTLEBORO, MA /PRNewswire/ -- The use of electronic pressure sensors in commercial HVAC/R systems has been restricted due to the high levels of electrical noise these systems generate. Sensata Technologies today announced a new sensor offering that overcomes these dense electromagnetic interference (EMI) barriers, enabling HVAC/R system designers to integrate reliable and accurate pressure transducers into their system designs. The company will be showcasing their new 2CH series of case isolated pressure sensor products during the AHR Expo, in Dallas, Jan. 29–31, at booth #3155.

The 2CH case isolated pressure transducer features EMI protection of 100 V/m and a dielectric terminal-to-case strength of 1.8 kVac. With pressure ranges between 100–750 psi and a burst pressure rating of up to 4X operating pressure, this device is ideal for 'electrically challenging' environments such as inverter-driven compressors and advanced HVAC/R systems. This new ceramic capacitive, hermetic sensor is available in a variety of pressure ports and electrical fittings.

"The 2CH sensor can be used across a wide range of refrigerants and temperatures and it is priced to meet the industry's design-to-cost goals," said John Forsyth, HVAC marketing manager, Sensata Technologies. "System designers can now benefit from an electrically stable, hermetic sensor designed specifically for use in HVAC and refrigeration applications."

Sensata Technologies will also be showcasing a new, low-cost plastic port fitting sensor design and a low profile transducer during the AHR Expo. The plastic port fitting is ideal for lower pressure applications within commercial and residential HVAC/R where cost, weight and corrosion resistance are of paramount importance. Applications such as low pressure cut out and general low pressure monitoring for the compressor are ideal for this new product. Designed for high volume production, the low profile sensor enables designers to integrate the transducer into system controls, saving design space and cost.

Sensata Technologies' pressure sensors come in a wide range of fittings, packaging materials, pressure ratings and electrical inputs/outputs. The company will be exhibiting at and available for comment during the AHR Expo in Dallas Jan. 29–31, at booth #3155.
