Abstract:
1. An apparatus to be assembled between a pump and a motor driving the pump for measuring torque and speed comprising: a housing having a motor attachment port and a pump attachment port; a primary coil supported by the housing; at least one shaft having a first outer end adjacent the motor attachment port of the housing for attachment to a motor, a second outer end adjacent the pump attachment port for attachment to a pump, and an inner portion located within the housing, the at least one shaft having angularly spaced ridges and grooves formed on an axially and circumferentially extending exterior portion of the at least one shaft; a strain gauge transducer component operably associated with the at least one shaft; a secondary induction coil sheathing the inner portion of the at least one shaft and mounted on an external surface of the at least one shaft, the secondary induction coil located sheathed within the primary coil and operably connected to power the strain gauge transducer component; and a speed sensor supported by the housing for sensing passage of the angularly spaced ridges and grooves formed on the exterior portion of the at least one shaft.
