Sensor for output torque

Post by hebi_newbie » Tue Dec 31, 2019 3:52 pm

Is the output torque sensor using the current supplied to the motor or is it using another method? Is there an accuracy rating for the torque sensor's measurement?

The output torque is directly sensed using a spring built into the output of the actuator. The sensor is behind the output shaft seals and does not measure seal drag, so the reading is accurate to about +/- 0.5 Nm or +/- 10% full value, whichever is greater. The resolution of the torque reading is about 0.01 Nm.
