Precont® KT

Analog pressure transmitter with ceramic diaphragm strain gauge

Application description

The device is an electronic pressure transmitter for monitoring, control as well as continuous measurement of pressures in gases, vapors, liquids and dusts.

Due to the device construction with measuring ranges from 0 bar to 600 bar (gauge), measuring ranges from 1 bar to 40 bar (absolute), measuring spans from 250 mbar to 600 bar,  process temperatures from –40°C to +135°C, environmental temperatures from –40°C to +85°C, process materials Al2O3-ceramic / CrNi-steel as well as the availability of industrial standard process connections like thread connection ISO 228-1 (EN 837 manometer), thread connection ISO 228-1 (inner thread), thread connection ISO 228-1 (EN 1179-2 E), thread connection ISO 228-1 (inner bore) the device is especially suitable for the use for machinery and plant engineering, air-conditioning and refrigeration plant engineering, hydraulic and pneumatic systems, process industry, environmental technology and facility and building automation.

The pressure transmitter is suitable for cost sensitive as well as demanding measuring requirements. 

The certification acc. to ATEX II 1 G Ex ia IIB/IIC Tx Ga allows the use in explosion hazardous areas.

The robust design and the high-quality workmanship turns the device into a very high quality product, which even the most adverse environmental conditions cannot affect, whether the lowest temperatures when used outdoors, extreme shock and vibration stress or aggressive media.

A captive laser marking of the type label ensures the identifiability throughout the entire lifetime of the device.

Obviously is the optional marking of a measurement point designation resp. TAG, a customer label or of a neutral type label, of course also per laser marking.

A LABS-free resp. silicone-free version, a factory calibration with calibration certificate and a customer specific configuration resp. preset is also optionally available like a material test certificate EN10204 3.1.

  • Integrated evaluation electronic: current output 4…20mA / Voltage output 0…10V / connector plug M12 / connector plug EN 175-301-803-C / -A / connection cable with integrated reference air capillary

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.
