Diaphragm pressure gauges MAN-C - Kobold

Kobold all stainless steel diaphragm pressure gauges are preferably used for aggressive media where standard diaphragm pressure gauges are challenged. Diaphragm pressure gauges have a relatively high actuating force. The circular diaphragm is insensitive to jarring or vibration. An extremely high resistance to overpressure is achieved by underpropping the diaphragm.
For highly viscous, crystallizing or strongly heterogeneous media, open flange connections are used. The wetted parts are coated by high quality polymers (PTFE/ECTFE) for specific use with aggressive media. Also the used seals are made of PTFE or covered by it.

In contrast to pressure gauges assembled with membrane chemical seals, the accuracy and zero point stability is ensured over a bigger temperature range. Even the mechanical stability and robustness is multifold in comparison to sensitive membrane chemical seals.
