RTSX Torque Sensor Operation Instructions
Rev 2.0 (5/16/2011)
Calibration Procedures
1. Attach the RTSX securely to a stand that
keeps the Rotary torque sensor in a stable
position for the calibration process with the
cable connector toward the top.
Mountz offers Rotary Fixture Stands for
calibrating Rotary Torque Sensors.
Model: RFS-200 (Torque Range 1- 200 lbf.in)
Item # 060234
Model: RFS-500 (Torque Range 5- 500 lbf.ft)
Item # 062032
2. Connect the RTSX to a torque tester/
display. Review the torque range of the
torque sensor and select the appropriate
measurement units.
3. Determine type of calibration to be performed.
Calibration at 3 Pts.
Test at 10%, 50% and 100 of Full Scale.
Calibration at 6 Pts.
Test at 10%, 20%, 40%, 60% 80% and 100 of Full Scale.
Direction
Clockwise and/or Counter Clockwise
4. Select the appropriate Calibration Arm or Wheel. Attach it to the output drive of the RTSX.
5. Gently connect the Hanger to the Calibration Arm or wheel.
6. Load 3 times to minimum 80% FS in direction of operation and reset to zero after loading.
7. Apply series of increasing torques in direction of operation starting from the lowest test point.
8. Record readings from the test device at each test point prior to performing any adjustments.
9. Repeat steps 6-8 in the opposite direction (if required).
10. Perform calibration adjustments. Repeat test as described above until readings at all test points are within tolerances.
11. Repeat test as described above and record 5 readings from test device at each test point. Compile all necessary details
to generate test report.
12. Remove old calibration label and place new label on torque sensor.
Maintenance Procedures
1. Recommend cleaning cycle is approximately 1,000,000 Revolutions.
2. Loosen the 4 fixing screw and remove the cover plate.
3. Use a soft linen cloth, a fine hair brush or oil-free compressed air to clean the
dust from the slip-rings and the spaces between them. Carefully clean the
brushes and the plastic part with the spring using a hair brush or oil-free
compressed air. Also clean the connector.
4. Measure the brush thickness, it should be more that 0.5 mm. New brushes can
only be fitted at the manufacturer.
5. Replace the cover plate carefully and re-tighten the fixing screws.
6. The Rotary Torque Sensor should be recalibrated every year.
