This accuracy is critical for tools in all industries, be it a tool for use with bone screws used in prosthetic surgery, a click torque wrench for tightening a car’s wheel nuts or a torque wrench used for aviation, construction and heavy machinery assembly.
Torque control and calibration experts Advanced Witness Systems Ltd have released their Universal Torque Wrench Calibration Machine (UTWCM), which provides an efficient and cost-effective means of calibrating and testing manually operated torque wrenches to international or company specific standards and specifications. It is designed to calibrate and test wrenches up to 2,500 Nm and equivalents.
The AWS UTWCM removes the need for operators to manually apply, at the right speeds, high forces when calibrating large torque wrenches. Instead, the machine applies the force using AWS proprietary firmware, a stepper motor and linear guide system. This set-up assists in minimising the parasitic forces applied to the torque wrench handle. Multiple safety features ensure that the machine, transducers and torque wrench are not overloaded in operation or over driven due to a wrench fault.
The fully-automated UTWCM uses AWS Intelligent Inline Torque Transducers, and the AWS Professional Transducer Display, to provide feedback to the microcontroller. Other manufacturer’s transducers may be used with our Intelligent Instrumented Transducer Cables. The display can be easily connected to the ADMS Kepler 4 Calibration and Conformity Software for ISO 6789:2017, ISO 6789:2003 or in-house standards (Sold Separately), for a complete calibration solution.
The benefits of the UTWCM being automated, reliable, maintenance-free, quick and easy to use, energy efficient and quiet are highly desirable; calibrating torque wrenches to the new standard has never been faster or simpler.
