Thin-film-on-steel (welded and O-ring free)or thick-film-on-ceramic pressure sensors are key components of Trafag pressure transmitters. Both sensor technologies as well as the ASIC (application-specific microchip) have been developed and produced in-house. As a result, compact pressure sensors and electronics work in perfect partnership and achieve a unique level of long-term stability and reliability even under the most adverse environmental conditions. Trafag is a technological pioneer when it comes to miniaturising robust pressure transmitters.

Thin-film-on-steel technology

  • Very good long term stability
  • Resistant at high media temperatures
  • Completely welded stainless steel sensor system without O-rings
  • Resistant to very high over pressures and ideal for nominal pressures up to 3000 bar

Thick-film-on-ceramic technology

  • Resistant to aggressive media
  • Ideal for low pressure ranges and absolute measurement
  • Economical
