Diaphragms are mainly used when, for example, very hot or highly corrosive processes do not allow direct contact between pressure gauges and the process medium.


Diaphragms or disk springs are our basic elements for pressure measurement. They can be referred to as pressure-stroke converters. Two membranes connected to each other at the edge result in a differential or absolute pressure measuring cell. Separating membranes are usually used as pressure transmitters between the medium and the sensor element.

Diaphragms are available in various highly resistant materials and different designs to ensure compatibility with a wide range of pressure measuring devices.
