gaseous media. The parameter "pressure" is converted into an analog voltage signal. Typical areas of application include:
Compressors
Refrigeration and HVAC/R
Variable-frequency drives
FEATURES
Compact, rugged design
Accurate relative pressure measurement over a wide temperature range
Rated IP65
Rapid response tim
