Comprehensive diaphragm seal portfolio for all process applications
The OPTIBAR DS diaphragm seal series are used for pressure, density and level measurement, in particular for high process temperatures of up to +450 °C / +842 °F, for corrosive media, or in conjunction with different hygienic and pharmaceutical process connections. The form of the diaphragm seal (inline or membrane diaphragm seals) depends on the individual process requirements.
Diaphragm seals protect the pressure transmitter in order that its sensitive diaphragm does not come into direct contact with the process conditions. A diaphragm seal consists of a separating diaphragm, the process connection, the transfer pipe (e.g. capillary or cooling element) and the pressure transfer liquid. The process pressure acts on the separating diaphragm and is transferred to the membrane of the pressure transmitter via the transfer pipe. The liquid in the diaphragm seal is selected dependent on the application and the temperature range of use.
All OPTIBAR DS diaphragm seals can be individually manufactured from a suitable material according to the process conditions. The most difficult measuring tasks are also reliably achieved.
