Integrated pumping well polished rod axial force and torque sensor

Disclosed is an integrated pumping well polished rod axial force and torque sensor. The sensor is provided with a strain body. The surface of the stain body is attached with a strain gauge. The strain gauge is connected with a circuit board. The strain body is cylindrical with openings at two ends. The two end parts of the strain body are provided with an outer thread or an inner thread. The strain gauge is an axial force strain gauge or a torque strain gauge. The outer thread or the inner thread at the two end parts of the strain body is respectively connected with one end of two polished rods, so that the strain body and the two polished rods form an integrated pumping well polished rod. In an operation process of the pumping well polished rod, the axial force and torque of the polished rod can be measured through the strain body, the strain gauge disposed on the strain body and the circuit board. The sensor is simple and reasonable in structure, convenient to install, high in measuring precision, and reduc
