Description

Product Details

The CheckStar rotary torque transducer sets the standard for dynamic torque and angle measurement of all continuous drive and impulse tools, with proven reliable performance in thousands of applications worldwide.

Whatever the vibration and shock loads experienced, CheckStar’s patented contact system ensures a connection is always maintained between the readout and the strain gauges. Inferior systems suffer from ‘brush bounce’ that leads to unreliable torque readings.

The CheckStar rotary torque transducer is automatically recognized by Crane readout devices, eliminating set-up errors and enabling the logging of serial numbers against measurements for complete traceability. The CheckStar is used in numerous applications for measuring torque such as assembly tool testing or assembly fastener torque auditing.

An Industry Standard (IS) version is also available where a user needs the advanced features of the CheckStar but already has a readout device from another manufacturer.
