Torque Transducers
Torque transducers or sensors are instruments that are used to measure the torque on rotating systems like engine crankshafts and bicycle cranks. They convert power from torque into electric power in order to transmit measurement signals to an electronic mechanism. This mechanism then transfers the message to devices like computers, chart recorders, and digital panel meters. After receiving the measurements from the transducer, these devices then process and interpret the data.
Rotary torque transducers can have two different connection configurations. In a floating shaft alignment, the transducer is connected to a rotating rod in between the motor and the pillow block. In a foot mount alignment, the transducer is instead connected on the bottom as well as on the sides.
In both connection designs, couplings should be attached to the rod on either side of the transducer, but single couplings should be used for floating shaft designs and double couplings are needed for the foot mount design. The coupling protects the transducer from being bent and will prevent misalignment.
