TempC Membrane

Highest accuracy and safety in pressure and differential pressure measurement with diaphragm seals.

In processes with very high or very low temperatures, aggressive media or strong vibrations, diaphragm seals offer optimum measuring results. To measure even more precisely in such applications and to increase process safety, Endress+Hauser has developed the TempC Membrane on basis of a completely novel technology. The patented temperature compensating TempC Membrane guarantees highest accuracy and increased process safety thanks to its new technology.

  • The very low temperature effect minimizes the influence of fluctuations of both process and ambient temperatures thus guaranteeing accurate and stable measurements. Temperature-effects on the signal are reduced to a minimum.

  • TempC Membrane may be used in the temperature range of -40°C and 250°C. This guarantees the highest degree of process safety also in tanks and pipes which are cleaned or sterilized (CIP/SIP) at high temperatures, even for very long cycles.

  • Thanks to the TempC Membrane, smaller dimension process connections are possible. The new diaphragm detects with a smaller process connection more accurate than conventional diaphragms with a larger diameter.

  • Fast membrane recovery after temperature shocks of the diaphragm permits shorter downtime in batch applications and thus a significantly higher availability of production facilities.
