What is a Torque Sensor or Transducer 

Torque transducers convert a torsional mechanical input into an electrical output signal to allow users to determine the torque of the torsional input. The output signal can be an analog, voltage, or digital USB signal.

These sensors fall into two types: Reaction and Rotary.

Reaction type sensors are used to measure resistance to a torsional input to produce a torque reading.

Rotary type sensors are used in applications where the transducer must rotate when attached to a spinning shaft or flange. A rotary transducer provides a means of getting a signal from the rotating element.

The TSCF is used in test benches for measuring the reaction torque (Wired and non-rotating). The torque transducer consists of two flanges, which are connected with each other via 4 measuring spokes. The two flanges have the same bolt circle of 149 mm. The pilots are designed as an external and internal collar with Ø 114.3 mm. Due to the large diameter of the torque transducer TSCF and the arrangement of the measuring spokes in the axial direction, this torque transducer can also absorb bending moments up to 200 Nm, which are caused by the dead weight of the drive motor. The connection is made via a terminal box with M12 connectors. Optionally, an integral measuring amplifier can be provided instead of the terminal box so that the transducer has a voltage output of +/-10V.
