Omega TQ501 Series Owner Manual

Below you will find brief information for Rotary Torque Sensor TQ501 100, Rotary Torque Sensor TQ501 200, Rotary Torque Sensor TQ501 500, Rotary Torque Sensor TQ501 1K, Rotary Torque Sensor TQ501 2K, Rotary Torque Sensor TQ501 5K, Rotary Torque Sensor TQ501 10K. The OMEGA TQ501 Rotary Torque Sensor is ideal for measuring torques in rotating shafts. An integral slip ring assembly is used to transfer the electrical signal from rotating electronics to stationary electronics. The slip ring consists of silver graphite brushes which rub on the rotating ring, providing an electrical path for the incoming excitation and the outgoing signal voltage. Because of the low signal levels produced by a strain gage bridge, brushes should be periodically cleaned. For long term measurements, the brushes can be replaced.

Frequently asked questions

The sensor uses a strain gauge bridge to measure the amount of torque applied to the shaft. The strain gauge bridge is connected to a slip ring assembly which transfers the electrical signal from the rotating shaft to stationary electronics. The output of the sensor is in mV/V, which represents the change in millivolt output from zero load to the full scale capacity of the sensor.

The TQ501 sensor is available in a range of models with different torque capacities. The available models are: TQ501-100, TQ501-200, TQ501-500, TQ501-1K, TQ501-2K, TQ501-5K, TQ501-10K. Each model has a different full scale capacity, measured in inch-pounds (in-lb).

While the TQ501 Rotary Torque Sensor is a very rugged device, it should not be subjected to torsional loads in excess of 150% of its rated capacity. The sensor can be used to measure torque in both clockwise and counterclockwise directions. When alternating clockwise and counterclockwise torsional loads are applied to the sensor, there should be no play in either loading direction. It is very important to have the proper shaft couplings installed in your system.

The accuracy of the TQ501 sensor is 0.18% of full scale. This means that the measured torque value will be within 0.18% of the actual torque value.
