CẢM BIẾN ÁP SUẤT APLISENS MODEL PC-29A and PC-29B

Application and construction

The PC-29A and PC-29B pressure transmitters are 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 65 to IP 68,

depending on the type of electrical connection applied.

Calibration

Potentiometers can be used to shift the zero position and the range by up to ±10%, without altering the settings.

Measurements under explosion hazard

ATEX Intrinsic safety version is available for taking measurements in zones under explosion hazard. The installation of the transmitter in a

zone under explosion hazard requires the use of a Ex power supply. We recommend the use of the Aplisens ZS-30/1Ex power supply and

separator.
