Push rod fitting for measuring process variable e.g. pH value in process fluid, has locking device provided in form of bayonet like bolting locking ring, which is rotatable between unfastened and locking rotational positions

摘要

The fitting has a measuring sensor (5), which is designed for detecting process parameters, where the measuring sensor is arranged in an axially displaceable slide pipe (6). A locking device is provided for the axially displaceable slide pipe in the form of bayonet like bolting locking ring (34). The ring is rotatable between a unfastened rotational position and a locking rotational position, in which it engages with axially movable component of the slide pipe or the locking device in a form fit manner.
