CheckStar from Crane Electronics Ltd
CheckStar transducers fit in-line between the assembly tool and the fastener, measuring the actual torques applied under production conditions.
Crane’s 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.
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.
CheckStar forms an essential part of the Crane UTA torque system, enabling “plug & play” operation with Crane readout devices. On board intelligence means the UTA CheckStar is automatically recognised by Crane readout devices, eliminating setup errors and enabling logging of serial number against measurements for complete traceability.
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.
Both versions can be specified to include an angle encoder with 0.5° resolution.
