UTA Dynamic Transducers
Checkstar Rotary Torque Transducer
The CheckStar rotary torque transducer sets the standard for dynamic torque and angle measurement of all continuous drive and drive tools, with proven reliable performance in thousands of applications worldwide.
Whatever vibration and shock loads experienced, CheckStar's patented contact system ensures that a connection is always maintained between the reading and the strain gauges. Inferior systems suffer from "brush bounce" which leads to unreliable Torque readings.
Description
UTA CheckStar forms an essential part of Crane's UTA torque system, enabling plug & play with crane reading devices. Onboard intelligence means the Crane reading device automatically recognizes the UTA CheckStar, eliminating configuration errors and allowing serial number registration against measurements for complete traceability.
