Position Transmitter Assemblies For Use With Actuators

A position transmitter assembly for use with an actuator stem of an actuator, the position transmitter assembly, comprising:

• a mounting bracket arranged for attachment to the actuator;
• a position transmitter operatively coupled to the mounting bracket;
• an arm, the arm including a first portion and a second portion, the arm being movable relative to the position transmitter, based on a position of the arm and a relative position between a position sensor and a feedback array, the position sensor to determine a position of the actuator;
• an anti-rotation bracket coupled to the mounting bracket, the anti-rotation bracket including a slot, the arm is positioned in the slot to prevent the arm from rotating;
• a cam assembly including a cam and a follower, the cam is arranged for attachment to the actuator stem, the follower is coupled to the arm at the second portion of the arm, the cam includes a convex profile and the follower includes a concave profile,
• wherein the coupling between the follower and the arm and an interaction between the arm and the anti-rotation bracket prevents the follower from rotating, and wherein the convex and concave profiles are arranged such that:
• 1) in a first position of the cam, the convex and concave profiles matingly engage and axes of the cam and the follower are substantially perpendicular;
• 2) in a second position of the cam, first surfaces defining the convex profile engage second surfaces defining the convex profile, thereby causing the follower to linearly move relative to the cam, in the second position, the axes of the cam and the follower are between being substantially perpendicular relative to one another and being substantially parallel relative to one another;
• and 3) in a third position of the cam, the follower is further linearly moved relative to the cam, in the third position, the axes of the cam and the follower are substantially parallel relative to one another.
