Pressure sensor

摘要

The sensor has a casing (100) that is open to the process medium and has a bore (111) to hold a ceramic pressure-measuring cell (120). The pressure-measuring cell has a ceramic membrane (121) on a ceramic base body (122) to face the process medium. An electronic part (130) and electrodes (124a,b) produce an electric signal corresponding to deflections in the membrane corresponding to the pressure to be measured. The membrane is resilient in the axial direction against a first end stop (114) in the casing. The base body is supported on a nonmetallic intermediate body (140), which is held in the casing by a metallic fastening device (150). The intermediate body is radially movable against the metallic fastening device.
