Casing for sensor used to monitor process medium, has lever and knee joint mechanism for moving sensor holder between sensor service and operating positions

摘要

A sensor holder (1) extends into a casing (2) acting as a valve and provided with a lever (3) and knee joint mechanism (16) for moving the sensor (5) between service and operating positions. A fitting for a sensor that allows the sensor to be removed from a process medium (24) without the need for the system to be drained or disturbed in any other way, comprises a casing with a seal (7), into which the sensor holder extends. The fitting is used to move the sensor between service and operating positions, as well as acting as a valve. Movement is carried out using a lever with a knee joint mechanism.
