ABSTRACT:
A polished rod load transducer for connection to the polished rod for measuring the load in a sucker rod well pumping system in which the transducer body has at least three symmetrical sections pivotally connected together with a clamping means connected to the body for clamping the body about a polished rod. A strain gauge is mounted on each of the sections and the strain gauges are equally spaced about the body when the body is clamped on a polished rod. An electrical circuit is connected to all of the strain gauges for measuring the total output from all of the strain gauges whereby an accurate measurement of the axial strain in the polished rod can be obtained in spite of the fact that the polished rod may be subjected to bending or be under or oversized. Preferably, the strain gauges are connected in series in one leg of a Wheatstone bridge circuit.
