Small torque tools go out of calibration with use. To maintain consistent accuracy, small torque tools must be checked periodically for wear or defective parts. A small power or hand torque tool is a measuring tool that must be properly calibrated and maintained.

The easy-to-use EZ-TorQ digital torque tester is ideal for all small hand torque and non-impacting torque power tools. The small size and portability of the torque tester makes it ideal for checking torque tools on production floor daily or weekly to ensure the tools aren’t falling out of calibration. The concept of torque validation is a central theme in every successful quality assurance program.

As a torque controlling, monitoring and documentation solution, the EZ-TorQ II enables operators and engineers to ensure product quality, safety and reliability promptly on the production floor. The EZ-TorQ II can calibrate hand torque screwdrivers and wrenches as well as power tools to avoid over tightening problems such as stripped fasteners and parts, under or over torque tightening problems, which can increase liability and risk of recall.

A regular torque tool calibration and re-calibration guarantees the operator repeatable accuracy and adherence to international standards. Torque testing also ensures torque equipment is operating to peak performance and can highlight potential tooling problems before they arise perhaps due to tool wear or broken components.

Experience, Quality and Reliable
In the manufacturing and assembly world, tightening, controlling, or measuring torque fasteners is imperative for production efficiency. An inadequately torqued fastener can vibrate or work loose: conversely, if the tension is too high, the fastener can snap or strip its threads. Faced with these problems, manufacturers are realizing that precise torque control can spell the difference between a safe, reliable, and economical product and complete disaster.

Anybody who has to tighten a threaded fastener and needs to control, monitor, or measure torque needs sophisticated torque tools. If manufacturers want to save money, make their workplace safer, enhance product quality, or reduce their exposure to liability; only specialized high-quality torque tools will get the job done properly.

1. Pick the Right Torque Tool
A wide variety of torque tools are available to control or measure the torque applied to fasteners, from electric screwdrivers to large industrial torque wrenches, torque analyzers, torque sensors, pneumatic screwdrivers and torque multipliers. These tools utilize calibrated torque setting mechanisms that may be factory pre-set or user-definable. When the specified setting is reached, the tool gives a visual, audible, or tactile signal. The anticipated production output, the type of materials being joined, the amount of torque required, and the specified fasteners determine the selection of tools for a given application. Lighter materials such as wood or plastic may require only lightweight tools; likewise, heavy materials such as steel may require stronger or larger tools. If torque data must be gathered during the assembly process or quality process, tools should also have connection ports such as USB, RS-232 and other cabling connections.

2. Establish a Torque Calibration Program
Calibration is fine-tuning the torque control process in a production environment. Torque calibration should be checked periodically to determine whether torque tools are operating at their proper settings. Many tools don’t have a locking device, and users may easily change their torque settings. When this happens, the tool falls out of adjustment.

A regularly scheduled calibration program enables quality control personnel to correct divergence from proper settings, whether it’s because of normal slippage over time or because of adjustments to the tool. Begin by setting a calibration interval initially based on severity of the application and the tool manufacturer’s recommendations. If the applied torque values are out of range, cut the calibration interval in half and re-test the tools.

A brushless rotary torque sensor is a finely tuned instrument designed for monitoring and testing torque applications where accuracy and reliability rank paramount. Designed for torque evaluation and verification, the brushless rotary torque sensor is a laboratory grade instrument that is commonly used for quality control, R&D and calibration applications.

For use with most power tools, high RPM tools, or rotational torque measurement applications, a brushless rotary torque sensor provides a higher level of accuracy over other standard rotary torque sensors. By connecting a brushless rotary torque sensor between an electric or pneumatic tool and an assembly application, you can monitor the torque being applied from the tool to a fastener or bolt. The torque sensor plugs into a torque tester or torque meter to display and capture the torque readings.

This special class of torque sensor is particularly valuable for measuring torque on pulse tools with strong vibrations. When using a standard rotary torque sensor for testing a pulse tool, there is a common “brush bounce” that plagues the testing accuracy. A brushless rotary torque sensor solves that issue and delivers consistently accurate readings ? whereas brushes within standard rotary torque sensors can bounce on the armature slip rings, which can impact the accuracy of the torque readings.
