Hydrocont M

Function

The fill level sensor Hydrocont M is put into the medium by the carrying cable by using a suitable fixing e.g. cable clamp fixing, screw plug or connection housing.
The liquid medium contacts directly without using a pressure transferring liquid the ceramic membrane. There the liquid causes a deflection of the membrane because of the hydrostatic pressure of the medium. At the maximum deflection the membrane contacts a robust ceramic carrier. Because of this, the membrane come through over pressure of e.g. 25-times of nominal load at a sensor with a pressure range of 0…100 mbar without damage.
The filling level proportional hydrostatic pressure signal of the ceramic membrane is measured by the integrated analogue electronic and converted in a output current signal of 4 to 20mA.
The measurement signal range is adjusted by factory in many standard measurement ranges. A factory provided adjustment by customer specification is also possible.
Optionally a temperature dependent resistor Pt100 in 3-wire-technic can be integrated in the sensor. By this temperature measurement resistor a temperature measurement of the filling medium with removing the lead resistance can be realized in parallel to the filling level measurement. When using a wall mounting connection housing a Pt100 transmitter that is adjusted by customer specification can be integrated.
Integrated over voltage protection components prevents the filling level sensor from destruction by atmospheric influences like e.g. thunderstrike.
