Precont® LTM

Advantages

The device is an electronic pressure transmitter for continuous measuring of relative pressures in gases, vapors, liquids and dusts within closed container or pipes.
The use of a dry/oil-free thin-film measuring sensor on metallic membrane offers excellent characteristics like high pressure and pressure blow strength, vacuum resistance, high accuracy, good long term stability and a low temperature influence allows the use in nearly all fields of industry.
The certification ATEX II 1G (zone 1) resp. ATEX II 1D (zone 20) in ignition protection type intrinsic safety allows the use in applications with combustible gases or dusts.
For Applications with high process temperatures up to +125°C resp. +200°C appropriate versions are available.
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 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.
