The new brushless rotary torque sensor, by Mountz Inc., 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. Mountz offers various brushless rotary torque sensor models that range from 1 inch-pound to 1,500 foot-pounds.

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.

Brushless rotary sensors are also available with a "torque & angle" configuration. The brushless rotary torque and angle sensors are designed for precision torque testing. These sensors can be used for measuring the rotation angle of a fastener, joint testing and breakaway torque.

The accurate measurement of torque applied to rotating drives and fastening applications is an important criterion for evaluating production efficiency and quality assurance in manufacturing and assembly. There are many process monitoring applications that require a brushless rotary torque sensor be used to capture and record traceable measurement results.

Controlling torque is essential for companies to ensure their product's quality, safety and reliability isn't compromised. The failure of a three-cent fastener that isn't properly tightened can lead to catastrophic or latent failures. Fasteners that are insufficiently torqued can vibrate loose and excessive torque can strip threaded fasteners. Using a quality torque sensor has become increasingly important for many companies to ensure that proper torque is being applied and maintains gauge requirements associated with the ISO 9001 Quality Standard.
