mecanismo sensor de pressão

A pressure sensor unit consists of a shaft part adapted to be introduced in an opening through a pipe wall or chamber wall, and a flange part fastened on the outer end of the shaft part for providing sealing around the outer end of the opening. The shaft part inner end reaches in to engagement with a process fluid which pressure is to be measured. The inner end is provided with perforations for admitting process fluid into the inner room of the shaft part. In the inner room and straight behind the inner end it is arranged a block which constitute a base for a separating membrane for transferal of the process fluid pressure via a hydraulic pipe to a pressure sensor element in the flange part. The flange part is constructed as a thin walled pipe, which is enabled because of internal pressure equalization. Thus great savings is achieved by production of the pressure sensor unit.
