Cerabar SMeasuring principleCeramic process isolating diaphragm used for PMC71 (Ceraphire )➀➁Metallic process isolating diaphragm used for PMP71 and 000P01-PMP7xxxx-03-xx-xx-xx-000Ceramic sensorMetal sensor12341234Atmospheric vent (gauge pressure only)Ceramic substrateElectrodesCeramic process isolating diaphragmMeasuring elementWheatstone bridgeChannel with fill fluidMetal process isolating diaphragmCeramic process isolating diaphragm used for PMC71 (Ceraphire )The ceramic sensor is a dry sensor, i.e. the process pressure acts directly on the robust ceramic process isolatingdiaphragm and deflects it. A pressure-dependent change in capacitance is measured at the electrodes of theceramic carrier and the process isolating diaphragm. The measuring range is determined by the thickness of theceramic process isolating diaphragm.Advantages: Guaranteed overload resistance up to 40 times the nominal pressure Thanks to highly-pure 99.9% ceramic (Ceraphire , see also "www.endress.com/ceraphire")– extremely high chemical resistance compared to Alloy– less relaxation– high mechanical stability Suitable for vacuums Second process barrier (Secondary Containment) for enhanced integrity Process temperature up to 150 C (302 F)Metallic process isolating diaphragm used for PMP71 and PMP75PMP71The operating pressure deflects the process isolating diaphragm and a fill fluid transfers the pressure to aresistance measuring bridge (semi-conductor technology). The pressure-dependent change of the bridge outputvoltage is measured and evaluated.Advantages: Can be used for process pressure up to 700 bar High long-term stability Guaranteed overload resistance up to 4 times the nominal pressure Second process barrier (Secondary Containment) for enhanced integrity Significantly less thermal effect compared to diaphragm seal systemsPMP75The operating pressure acts on the process isolating diaphragm of the diaphragm seal and is transferred to theprocess isloating diaphragm of the sensor by a diaphragm seal fill fluid. The process isolating diaphragm isdeflected and a fill fluid transfers the pressure to a resistance measuring bridge. The pressure-dependent changeof the bridge output voltage is measured and evaluated.Advantages: Can be used for process pressure up to 400 bar High long-term stability Guaranteed overload resistance up to 4 times the nominal pressure Second process barrier (Secondary Containment) for enhanced integrityEndress Hauser5
