For high pressures and harsh environments, steel diaphragms have proven themselves in pressure sensor technology.
The most reliable measuring principles on steel diaphragms use so-called thin film technologies or alternatively strain gage technologies.
The latter are characterized by significantly higher raw signals compared to thin film technology.
Prignitz Mikrosystemtechnik uses both measurement methods.

With the P2P technology Prignitz Mikrosystemtechnik has developed a unique, patented Technology that belongs to the strain gauge technologies. The decisive and innovative difference to the competition is the use of two full bridges, which are interconnected in such a way that undesirable external force influences on the sensor signal (e.g. torques during installation) are largely compensated.
A monolithic steel body without any welding is used for this purpose. Only one part made of solid 316L stainless steel comes into contact with the medium. As a result, this technology can also be used for hydrogen applications.

For other applications, other materials such as 17-4PH, Hastelloy or others can be used. The high internal vertical integration from the assembly and connection technology (“AVT”) to the calibrated sensor system enables PMST on the one hand to respond quickly to customer requirements and on the other hand to maintain a high consistent quality level.

The P2P technology can be used in all our pressure sensor families S100, S200 and the C100.
