Rotary Transducer with Angle Measurement Option
CheckStar 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. CheckStar transducers fit in-line between the assembly tool and the fastener, measuring the actual torques applied under production conditions.
Whatever the vibration and shock loads experienced, CheckStar's patented contact system ensures contact is always maintained between the readout and the strain gauges. Inferior systems suffer from "brush bounce" that leads to unreliable torque readings.
The low inertia design of CheckStar 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.
