DST-01 Dynamic Torque Transducer With Couplings For Wrench Calibration
Reaction torque sensors are critical components in torque wrench calibration systems, providing precise measurement of applied torque while compensating for reaction forces.
1. Role in Calibration Systems
Reaction torque transducer integrate with calibration systems featuring stepper motor controls, torque sensors, and encoders to achieve manual, automatic, or electronic handwheel operation
They enable both open-loop and closed-loop control, ensuring calibration accuracy through real-time feedback
2. Critical Technical Features
TEDS (IEEE1451.4) Support: Automates sensor identification and calibration parameters, reducing setup errors
Robust Construction:
Stainless steel for corrosion resistance in industrial environments
Aluminum alloy for lightweight applications
Overload Protection: withstand 150% safe overload and 300% ultimate overload
Environmental Resilience: IP65-rated units , resist dust/water ingress
3. Integration in Calibration Workflows
Mounting: Flange/square-drive designs allow direct coupling with torque wrenches, minimizing misalignment errors
Signal Processing: Requires compatibility with:
Quadruplicated frequency circuits for noise reduction
Shielded cables (e.g., polyurethane/PVC-shielded) for precise low-noise measurements
Temperature Compensation: Critical for drift in variable lab/field conditions
