APRE-2000 ALW Smart differential pressure transmitter

The active element is a piezoresistant silicon sensor separated from the medium by separating diaphragms and a specially selected type of manometric fluid. The special design of the active sensing element ensures that it is able to withstand pressure surges and overloads of up to 250/320/420 bar. The display can be rotated from 0-340 degrees.
