We are specialists in position sensing, in other words feed back signal from a linear or rotary sensor. With our experience we will guide you to the best solution, no matter if you need some standard components from our stock or larger quantities of a customized sensor.

Ship-approved pressure sensors

Trafag transmitters are used for the sensing of pressure and the transmission of pressure proportional electrical signals.


  • Various process and electrical connections
  • Absolute/relative pressure measurement
  • Analogue/digital outputs
  • With/without bus interface
  • CE, EX or Marine Approvals
  • Trafag sensors are the basis of precise Pressure Transmitters.

    Method of measuring

  • Thin film strain gauge. The force of the measured media deforms the thin film strain gauges thereby producing an electrical signal.

  • Steel sensors
    Technology: Thin film on steel

  • Very good long-term stability
  • Resistant to high medium temperatures
  • All wetted parts are stainless steel (without additional material)
  • Very good overpressure resistance, ideal for nominal pressures up to 2000 bar
