OMEGA’s TQ202 Series Torque Sensor is a small high accuracy flange or surface mount device designed for measuring reaction torque forces up to 250 in-lb. The shaft attachment has three equally spaced flat surfaces to assure non-slip mounting without the use of a key. The all stainless steel construction provides long life in industrial environments, and its heavy duty construction assures long term high accuracy measurements.
The TQ202 is also available in metric configurations, with ranges from 0-0.175 to 0-28 N-m. Please see the TQM202 for complete details, or contact our Pressure department for more information.

Does this sensor measure torque in both directions? And if not, how are we supposed to know which direction is the measurement range? We have built this sensor into a device and our customer is saying they are only reading torque in one direction.
Asked by: Beaut0721
The TQ202 is only calibrated in the clockwise direction but it will read in both directions. If wired as indicated on the included calibration report you will see a (+) positive polarity millivolt output signal when torque is applied in the clockwise direction. If you apply a load in the counterclockwise direction you will see a (-) negative polarity millivolt output signal which would be a mirror image of positive signal. The instrumentation your customer is using may be set up to read only a positive polarity signal.
