Differential pressure gauges are ideal for the hard conditions and the resulting high demands on pressure measurement in production facilities in chemical industry and other comparable branches. The use of high quality materials such as stainless steel makes the measuring system and the case resistant against chemically aggressive media and ambient.

Differential pressure gauges with electrical alarm contactsare suitable for controlling or regulating process sequences with the aid of the process pressure.

The heart of these differential pressure gauges is the pressure chamber with two “hydraulically” connected diaphragms with a liquid bolster between the diaphragms. In case both diaphragms with a liquid bolster between the diaphragms are set under different pressure, the displacement into one direction is transformed by a movement to a proportional pointer deflection.


  • Level measurements in pressurised vessels
  • Filter monitoring
  • Flow measurement
