  • Application

    The Ceraphant is a pressure switch for the measurement of absolute and gauge pressure in gases, vapors, liquids and dust. The Ceraphant can be used universally thanks to a wide range of approvals and process connections.

    Function

    Ceramic process isolating diaphragm: The ceramic switch is an oil-free sensor, i.e. the process pressure acts directly on the robust ceramic  process isolating diaphragm and causes it to deflect. A pressure-dependent change in capacitance is measured at the electrodes of the ceramic substrate and the process isolating diaphragm.

    Metallic process isolating diaphragm: The process pressure deflects the metal process isolating diaphragm of the switch and a fill fluid transfers the pressure to a Wheatstone bridge (semiconductor technology). The pressure-dependent change in the bridge output voltage is measured and evaluated.
