PTMExFG / PTMExFBFG Applications Pressure transmitters model PTMEx are suitable for liquid and gaseous media that do not corrode stainless steel. When connecting to a certified intrinsically safe circuit, the instruments have the type of protection II 2G Ex ib IIC T6 Gb according to ATEX. Two basic models are available: Overpressure Model PTMEx 0 - 1 bar to 0 - 400 bar Model PTMExFB 0 - 1 bar to 0 - 60 bar both versions also for vacuum and compound ranges (with ventilation to the atmosphere) Absolute pressure (a) 0 - 1 bar to 0 - 25 bar (reference point zero absolute) The pressure transmitters are temperature-compensated and provide a calibrated output signal. The robust construction enables the application under difficult conditions, e.g. in shipping. EMC-Examination The pressure transmitters fulfil the stability requirements for the industrial sector, for residential and commercial areas according to the European standard and hence grant their electromagnetic compatibility. Construction The pressure transducer element is welded in the pressure connection piece. A thin stainless steel diaphragm separates the elementary sensor from the medium. For pressure ranges from 0 - 250 bar onwards, a thin film sensor is directly welded to the pressure connection piece.
