Pressure transmitters

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

Options

  • 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
Advantages:

  • 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

Ceramic Sensors
Technology: Thick film on ceramic
Advantages:

  • Resistant to aggressive media
  • Ideal for low pressure ranges
  • No filling with liquids behind the membrane
  • Excellent cost-performance ratio
