Details

The Motorized Torque Wrench Calibrator is a highly specialized, precision-engineered calibration system developed for evaluating and verifying the accuracy of various torque wrenches. Torque tools, particularly Torsion Beam types, Spring types, and other mechanical variants, play a critical role in assembly and maintenance operations across aerospace, defense, and heavy industries. Any degradation or drift in their calibration directly affects fastener tensioning, mechanical integrity, and overall operational safety.

To address this requirement, the Motorized Torque Wrench Calibrator enables accurate, repeatable, and automated calibration in strict accordance with ISO and defense standards. The system translates laboratory-grade precision into a robust, horizontal testing bench that can be utilized both in metrology labs and directly at maintenance facilities.

System Architecture and Control
The system is delivered as a robust horizontal model featuring a specially designed, fabricated testing table that ensures optimal stability during high-torque calibrations. Unlike manual testing rigs, this motorized unit is fully computerized, integrating advanced software compatible with the latest operating systems. 

This computerized control eliminates human error during torque application, ensuring a smooth, consistent load rate that is critical for accurate spring and torsion beam evaluations. The software provides an intuitive PC interface displaying real-time torque readings, making it easy for technicians to monitor the calibration process.

Precision Measurement and Accuracy
At the core of the calibrator is a highly sensitive torque transducer tailored for the 0 to 500 Nm range. This transducer guarantees exceptional precision, offering:
• A Least Count (LC) of 0.1 Nm
• An impressive accuracy of ± 1 % of the applied torque reading

The calibration process is validated across 20% to 100% of the operational range in 5 distinct steps, ensuring linearity and compliance across the tool's entire functional span. Measurements can be instantly converted and displayed in multiple configurations, including Nm, Kgm, Lbft, and Lbinch, providing flexibility for different regional or legacy standards.

Advanced Software Capabilities
The included software suite goes beyond simple torque display. It provides a comprehensive data management environment essential for modern quality control:
• Data Logging & Search: Complete data save and recall facilities with advanced search functionalities allow for strict traceability of all calibrated tools.
• Peak Hold Function: Automatically captures the maximum applied torque in both clockwise and anti-clockwise directions.
• Automated Protection: Features built-in overload protection software coupled with an audio indication system, safeguarding both the transducer and the tool under test from accidental damage.

Comprehensive Adapter Set
To ensure seamless compatibility with a wide array of torque wrenches and screwdrivers, the system includes a complete suite of precision-machined sockets and adapters:
• Hex 1/2 '' x Square 3/8''
• Hex 1/2 '' x Square 1/4''
• Hex 1/2 '' x Square 1/2''
• Hex 3/4 '' x Square 1/2''
• Hex 3/4 '' x Square 3/4''
• Hex 3/4 '' x Square 1''
• Dedicated Adapter for Torque Screwdrivers (Facom Make Part code A404 / Equivalent)

Documentation and Traceability
Understanding the stringent requirements of defense and aerospace MRO (Maintenance, Repair, and Overhaul), the system is supplied with complete documentation. This includes a detailed Operation and Maintenance Manual, initial Calibration Certificates, and a Certificate of Conformity (CoC). Furthermore, a suitable color printer is integrated into the setup to generate immediate, hard-copy calibration reports directly on the shop floor.
