Diaphragm Seals

Diaphragm seals are partitions in pressure measuring instruments that prevent the measured medium from entering the measuring system. This means that they protect the measuring equipment from aggressive, highly viscose or congealing measured media and high measured medium temperatures, dampen measurement pressure fluctuations and pressure peaks and increase overload resistance. In addition, they immediately remedy an unfavourable situation at the pressure measuring points and allow the use of pressure gauges in potentially explosive atmospheres and the elimination of dead space when arranging measuring points.

The design of diaphragm seals can vary greatly depending on the measurement task they support: LABOM is contributing to precise results and greater operating reliability with patented diaphragm types and customer-specific designs for diaphragm seals.
