Application description

The device Precont® KT with integrated analogue evaluation electronic is a compact pressure transmitter for continuous measuring of pressures from 0 up to 600 bar in gases, vapors, liquids and dusts within closed container or pipes, also in explosive hazardous areas, at process temperatures from – 40°C to +100°C.

The use of a strain gauge with ceramic membrane and the corresponding excellent characteristics, allows the use in nearly all fields of industry.

Function description

The device is mounted in the wall of the pressure container or of the pipe.

The system pressure is applied to the ceramic membrane and causes there a deflection of the thick film strain gauge at the back side of the membrane.

The ceramic membrane offers excellent characteristics like high pressure and pressure blow strength up to four times the nominal pressure, vacuum resistance, very high resistance against chemicals, corrosion and abrasion, very good insensitiveness against temperature shocks, high accuracy and reproducibility, good long term stability and a low temperature influence.

The pressure dependent variation of the strain gauge output voltage is converted by the integrated evaluation electronic into a current signal 4…20 mA resp. voltage signal 0…10 V.
