Abstract
Disclosed is a device for determining the diametral changes in a substantially cylindrical member produced by axial loads imposed on the cylindrical member, such as the valve stem in a motor operated valve assembly. The device is a clamp assembly comprised of a first jaw member and a second jaw member rigidly connected to each other and to the portions of the periphery of the cylindrical member by a pair of studs. The second jaw member has a flexure with a contact surface contacting a peripheral portion of the cylindrical member and a projection extending away from the contact surface to transmit compressive forces representative of diametral changes in the cylindrical member against a compression load cell housed in the second jaw member. The device is useful in the field of valve diagnostics.
