Hydrostatic level measurement: Measuring Principle

Contite cell: The measuring cell is absolutely protected between the process isolating diaphragm and the rear isolating membrane. Also it is absolutely insensitive to condensation and aggressive gases.

Ceramic cell: The ceramic sensor is a dry sensor, i.e. the process pressure acts directly on the robust ceramic process isolating diaphragm and deflects it. A pressure-dependent change in capacitance is measured at the electrodes of the ceramic substrate and the process isolating diaphragm.

Benefits

  • Maximum plant safety provided by one-of-a-kind, condensate-proof Contite measuring cell
  • Contite cell offers very good reproducibility and long-term stability even after temperature shocks
  • The ceramic cell has extremely good chemical compatibility and high mechanical stability thanks to ultra-pure 99.9% ceramic
  • Robust ceramic membrane with integrated membrane breakage detection - also suitable for vacuum applications
