Differential pressure transmitter with metal sensor for measurement of pressure differences PMD55-AA21BD67DGJHAJA1A+AAPB DELTABAR

A metallic process membrane (4) is deflected on both sides by the p1 and p2 pressures present. A fill fluid (3) transfers the pressure to a resistance circuit bridge (semiconductor technology). The change in the bridge output voltage, which depends on the differential pressure, is measured and processed further.
