TempC membrane brochure - .PDF file.

The TempC (temperature compensatory) membrane from Endress+Hauser is said to offer improved accuracy and process safety in challenging pressure and DP applications. It uses new technology to dramatically reduce the influence of process and ambient temperature fluctuations.

In applications with process temperatures from -40°C to 250°C, it offers a very short recovery time after temperature shock, for example, at the end of a cleaning-in-place/sterilising-in-place cycle when compared with conventional diaphragm seals.

Pressure and differential pressure transmitters are employed across all industries for many different applications such as process pressure measurement, hydrostatic level, differential pressure and even flow measurement, across filters, packing, heat exchangers and others.

Sometimes the application determines that the instrument requires a diaphragm seal design, typically due to extremes of process temperatures, corrosive media, plant vibration, viscous media or hygienic requirements.

While diaphragm seals are very useful in solving some challenging applications they can suffer from poor performance due to changes in both process and ambient temperature. Changes in temperature will cause the oil fill in the system to expand or contract. Conventional membranes can have a high degree of stiffness so the oil expansion or contraction has little effect on the membrane but instead acts upon the measuring cell therefore causing errors in measurement.

With this in mind, the TempC membrane has been designed to be much more flexible, therefore absorbing any oil expansion or contraction. This can typically reduce these measurement errors by up to 90 per cent, therefore providing much improved measurement stability, reliability and potentially greater process safety.
