CheckStar Multi Torque Transducer

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

Designed for high-precision assembly and quality control applications, the CheckStar Multi is one of the most accurate rotary torque transducers available, making it the ideal choice for demanding industries such as automotive and aerospace manufacturing. With over 40 ranges available, from 1Nm to 5000Nm, it can be configured to suit virtually any application.

A comprehensive choice of square and hex drives, with shaft sizes ranging from 1/4″ to 1.5″, ensures seamless integration with your existing tool calibration or fastener verification processes. Whether you are measuring the shut-off torque of a continuous drive tool or accurately monitoring an impulse tool, the CheckStar Multi delivers the accuracy and repeatability your process demands.

The CheckStar Multi incorporates a 360° light ring, giving the user visual feedback of the status of a tightening when used with a Crane readout or data collector.

The CheckStar Multi rotary torque transducer fits in-line between the assembly tool and the fastener, measuring the actual torque applied and the angular rotation of the fastener, under production and assembly conditions.

Whatever the vibration and shock loads experienced, the CheckStar Multi’s patented contact system ensures a connection is always maintained between the readout and the strain gauges. Inferior systems can suffer from “brush bounce” that ultimately leads to unreliable torque readings. The low inertia design of the CheckStar Multi ensures accurate and repeatable measurement of high speed transients, such as the point of shut-off on continuous-drive tools and the pulsing of impulse tools.

Using on board intelligence, the transducer is automatically recognised by Crane data collectors, eliminating set-up errors and enabling the logging of serial numbers against measurements for complete traceability.
