High temperature pressure sensor Type 6025B... WARNING: HAZARDOUS ENVIRONMENT Risk of explosive atmosphere. Adapters, isolation valves, or sealing rings that are not compatible with process gasses will corrode and fail. This failure may result in gas leaks, fire, explosion, or projectiles. Prevent corrosion and failure by verifying that all components are compatible as described in the installation procedures.
Pressure sensor 3. Pressure sensor Basic execution Sensor Type 6025B… is a 2-wire, internally ground isolated differential piezoelectric pressure sensor. The sensor is equipped with an integral mineral insulated hardline cable and is available with different cable terminations. Executions for operation in hazardous areas (Ex-versions) All sensors of the 6025BE...
This requires a differential charge amplifier. Depending on the required application, Kistler recommends the differential charge amplifier Type 5181, 5183 (Ex ia) or 5185 (Ex nA). Measuring...

High temperature pressure sensor Type 6025B... Operation in hazardous areas 4.2.1 Instructions for operation in hazardous areas In addition to the instructions for proper operation in Section 4.1.1 the following instructions must be followed for installation and operation in potentially explosive atmospheres: The sensor can be used in intrinsically safe ...
Type 6025BE… (certified ‚Ex-nA‘ and ‚Ex-ia‘) must be used. 4.2.3 Marking on sensor Minimal marking for "Ex-nA" and "Ex-ia" Due to lack of space the minimal Ex marking is engraved on the sensor. Kistler Type … SN … II 1G II 3G Ex ia IIC T6...T710°C Ga Ex nA IIC T6...T710°C Gc...
High temperature pressure sensor Type 6025B... 4.2.6 Intrinsically safe equipment (Ex-ia) 4.2.6.1 Intrinsically safe measuring chain, ground isolated (sensor version Type 6025BE…) The sensor can be used in intrinsically safe circuits of the zones 0, 1 and 2. For operation in hazardous areas, the sensor must be operated with an Ex-certified differential charge amplifier and a corresponding Ex-certified barrier.
Installation, service & maintenance 5. Installation, service & maintenance The installation bore as well as the proper installation of the sensor are essential to guarantee the specifications of the sensor. 5.1 Mounting bore Fig. 4: Direct mounting 5.2 Mounting/removal For the mounting and removal of the sensor generally accepted engineering practice...

The minimal bending radius is not smaller than 16 mm Be sure that the cable is not bent more than 10 times In case of a damaged hardline cable the sensor must be returned to Kistler. Fig. 10: Sensor with integral hardline cable 5.3.2 Softline cable In case of mechanical damage or cable failure the cable can be replaced and operation continued.
High temperature pressure sensor Type 6025B... 5.3.3 Hardline cable fixation The signal from the sensor to the differential charge amplifier is in form of a charge. The hardline cable and softline cable should therefore be fastened in such a way as to minimize cable vibration and thus minimize any triboelectric effects.
The recalibration interval depends on the conditions of use and is the responsibility of the user. Kistler will gladly advise you. For gas turbines it is recommended to recalibrate the sensor during each revision of the gas turbine.
