Arrangement for pneumatic or hydraulic pressure measurement, has pressure channels, which are opened synchronously with rotation of pressure measuring instrument

摘要

The arrangement (1) has a pressure measuring instrument (20) that is arranged rotatably inside a housing block (60), where the pressure measuring instrument is axially movable in one position and is axially fixed in another position. Pressure channels (64b) are opened synchronously with the rotation of the pressure measuring instrument, so that a paddle-shaped differential pressure sensor is applied with a pressure on the fluid located in the pressure channels to avoid the one-sided strain.
