Trycksensor för ett flytande tryckmedium

摘要

The pressure sensor has a measurement cell (12) in a housing into which the hydraulic medium to be monitored is introduced via a channel (13). A blocking device (14,15) in the channel is open in normal mode and closes automatically in the event of a leak near the measurement cell. The blocking device is closed by a pressure difference between the region in which the monitored pressure is active and the region of the measurement cell.
