CẢM BIẾN ÁP SUẤT APLISENS MODEL APCE-2000PD

Application
The APCE-2000 pressure transmitter is applicable to the measurement of the pressure, underpressure or 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.
