  • extremely resistant to shock, pulsation and vibration
  • high overload safety
  • best dynamic pressure resistance at high load changes
  • wetted area without seals due to welding
  • no transmission liquid

For electronic pressure measurement in industrial applications, e.g. hydraulic, pneumatic, gas industry, refrigeration, automation, medical, as well as general mechanical and plant engineering applications.

Pressure transducers convert physical pressure into an electrical signal proportional to the pressure. DMU 02 is equipped with a piezo-resistive polysilicon thin-film measuring cell.
