ABSTRACT:
A device for axial load measurement on a mechanical control device (10) having rotating shaft (30) maybe used to derive a torque measurement. A mechanical control device (10) may comprise a valve actuator for fluid flow control devices. The load measurement device may include a beam (65a) operatively connected to a rotatable shaft and configured to deform under axial displacement of the shaft. A sensor (80) maybe coupled with the at least one beam (65a) and configured to produce an output signal related to the axial displacement of the shaft. The beam may be retained between two bearings (74) of the rotatable shaft at a first end, and fixed to the housing (120) of the mechanical control device at a second end. The first end of the beam (65a) may displace axially with the rotatable shaft. The beam (65a) may comprise a discrete segment of a uniform width and thickness.
