The Mountz brushless rotary torque sensors are an ideal torque-auditing tool for testing the actual torque being applied on the assembly application. Particularly valuable for measuring torque on pulse tools with strong vibrations. By connecting a rotary torque sensor between an electric or pneumatic tool and assembly application, you can monitor the torque being applied from the tool to a fastener or bolt.
