Patented P2P technology

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 gauge 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 from 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.

Advantages of P2P technology:

  • Pressure ranges from 4 bar to 1,000 bar
  • Accuracy: 0,5% or better
  • Made entirely of 316L stainless steel, no internal welding, no internal seals
  • Temperature range: -40°C to +125°C
  • Customized solutions
  • Very high robustness against external forces
