OEM Pressure Sensors

Preface

We develop and produce OEM pressure sensors using thin film on steel technology for high standards in our own plant.
The pressure is measured using expansion measurement structures on a steel membrane.

Under pressure load the membrane changes shape, resulting in a change of the electrical resistance of the structure.

By manufacturing using progressive GFS thin film technology, and with our many years of production experience our products have the highest measuring accuracy and stability.
Used by manufacturers of pressure transmitters and pressure measuring systems.

Features

  • measuring structure is layered directly onto the steel
  • special steel membrane
  • highest accuracy and long-term stability
  • integrated temperature compensation or integrated temperature measuring resistor
  • optimum sensitivity due to strain gauge bridge circuit
  • resistant against extreme ambient conditions
  • customised design of the membrane and connection piece also possible
  • Scope of delivery:
    OEM sensor (=measuring cell with welded pressure connection and electrical connecting flex) or coated measuring cell
