TT-CA TT-CA Radius Arms / Torque Arms

The Checkline TT-CA  Radius Arms are designed for calibration and verification of torque measuring equipment.

The radius arms are available in 2 versions:
- High Accuracy Arms are for use with +/-0.25% tolerance transducers
- Standard Accuracy Arms are for use with +/-0.5% tolerance transducers.

High Accuracy version: 0.025% Accuracy

• TT-CA-.1MA High Accuracy Calibration Arm 0.1 meter radius 11 N-m Max
• TT-CA-.25MA High Accuracy Calibration Arm 0.25 meter radius 340 N-m Max
• TT-CA-.5MA High Accuracy Calibration Arm 0.5 meter radius 750 N-m Max
• TT-CA-1MA High Accuracy Calibration Arm 1.0 meter radius 1500 N-m Max

Standard version: 0.625% Accuracy

• TT-CA-.1M Calibration Arm 0.1 meter radius 11 N-m Max
• TT-CA-.25M  Calibration Arm 0.25 meter radius 340 N-m Max
• TT-CA-.5M  Calibration Arm 0.5 meter radius 750 N-m Max
• TT-CA-1M Calibration Arm 1.0 meter radius 1500 N-m Max

These radius arms are used by Metrology Labs and Quality Control (QC) Departments  to test and adjust torque torque transducers and sensors.

We offer a range of arms from 10 to 100 cm in length to calibrate equipment up to 1500 N-m.

The Checkline TT-CA Radius Arms include single weight pans.
Standard operating procedure is to install the arm, attach the weight pan then zero out the weight pan. The TT-CA calibration arms also include a wire with a loop on each side so you can supply your own certified hanger with slotted weights.

Note: Weights sold separately and are not available from Checkline.
