Application description

The device Precont® ML is an electronic pressure transmitter for continuous measuring of relative or gauge pressures in gases, vapors, liquids and dusts within closed container or pipes.

The use of a piezoresistive measuring sensor with EHEDG conformal metallic membrane and the corresponding excellent characteristics, allows the use especially in hygienic applications.

Function description

The device is mounted in the wall of the pressure container or of the pipe.
The system pressure is applied to the metallic membrane and causes there a variation of the resistance of the strain gage at the back side of the membrane.
The metallic membrane offers excellent characteristics like high pressure and pressure blow strength, vacuum resistance, high accuracy and reproducibility, good long term stability and a low temperature influence.
A FDA-listed pressure transmitting liquid is used for the transmission of the pressure from the membrane to the strain gage.
The pressure signal, that is transmitted by the membrane to the sensor is converted into an electrical signal and converted by the integrated evaluation electronic into a current signal 4...20 mA resp. voltage signal 0...10 V.
