CẢM BIẾN ÁP SUẤT APLISENS MODEL PCE-28/EXD

Application and construction

The PCE-28 pressure transmitter is applicable to the measurement of the pressure, underpressure and absolute pressure of gases, vapours and liquids.The active sensing element is a piezoresistant silicon sensor separated from the medium by a diaphragm and by specially selected type of manometric liquid.The electronics is placed in a casing with a degree of protection from IP 66 to IP 68.

Measurements under explosion hazard

ATEX Explosion Proof version is available for taking measurements in zones under explosion hazard.
