Application description

The device Precont® CT with integrated analogue evaluation electronic is a compact pressure transmitter for continuous measuring of pressures from –1 up to 16 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 capacitive measuring sensor 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 variation of the capacity at the back side of the membrane.

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

The pressure dependent variation of capacity 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.
