  • connection technology with numerous versions
  • extremely resistant to shock, pulsation and vibration
  • best dynamic pressure resistance at high load changes
  • measuring cell welded without seals
  • without transmission medium
  • Turn Down 1:4
  • Zero calibration via magnet

For electronic pressure measurement in mechanical and plant engineering, and for gas and medical applications. Particularly suitable for pure media.

Pressure transducers convert physical pressure into an electrical signal proportional to the pressure. DMU 02 Vario is equipped with a piezo-resistive polysilicon thin-film measuring cell. All standard electrical connection types are available. The measuring ranges can be changed via optional parameterisation hardware and software. The zero point can be corrected from the outside via a permanent magnet after voltage has been supplied and within a given time window.
