Abstract: An apparatus can be assembled between a pump and a motor driving the pump for a measuring torque and speed. The apparatus can include a housing having a motor attachment port and a pump attachment port. A primary coil is supported by the housing. A shaft has a first outer end and second outer end and an inner portion located within the housing. The first and second outer ends are connectible to a motor and a pump to suspend the shaft between the motor and the pump only by the outer ends of the shaft. A strain gauge transducer component is operably associated with the shaft. A secondary induction coil is mounted on the shaft and is located sheathed within the primary coil for providing power to the strain gauge transducer component. A wireless output of readings from the strain gauge transducer component is provided.
