The APR2000-ALW smart differential pressure transmitter series from Aplisens measures differential pressure of gases, vapours and liquids. 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 700 bar. The display can be rotated from 0-340 degrees.Main Features
