  • proven ceramic technology
  • no mechanical ageing of the measuring cell
  • no transmission liquid
  • Versions for relative pressure and absolute pressure
  • small temperature error

For electronic pressure measurement in industrial applications (such as hydraulic and pneumatic applications as well as mechanical and plant engineering).

Pressure transducers convert physical pressure into an electrical signal proportional to the pressure. DMU 01 is equipped with a piezo-resistive thick-film ceramic measuring cell.
