The APR-2000 ALW transmitter is applicable to the measurement of differential pressure of gases, vapours and liquids. The active elementis a piezoresistant silicon sensor separated from the medium by separatingdiaphragms and a specially selected type of manometric fluid. The special design of the active sensing element ensures that it is able towithstand pressure surges and overloads of up to 700 bar. The display can be rotated from 0-340 degrees.
