Abstract

An improved switch point setting device for fluid process sensors monitoring a process pressure, including a cylindrical housing, an elongated threaded shaft rotatably mounted in the housing, and a movable post member with a threaded base portion threadably mounted on the threaded shaft within the housing and a dog-leg post portion extending from the housing to form a pressure set point. A coil spring within the housing biases the threaded base portion in positive threaded engagement with the threaded shaft. An O-ring provided around the base portion on each side of the post portion enables threadable movement of the base portion during set point adjustment while otherwise maintaining the base portion reliably in position.
