Pressure signal transmission device has connection to pressure vessel leading to chamber with membrane and pressure fluid connected to pressure sensing instrument

摘要

The pressure signal transmission device has a connection (22,23) to a pressure vessel e.g. for a chemical process. The channel (21) leading from the pressure vessel enters a chamber under a membrane (30). Pressure fluid on the other side of the membrane is connected via a channel (11) to a screw connection (17) and a pressure sensing instrument. The membrane holder (10) and the lower part (20) connected to the pressure vessel are welded together (24).
