Tension meter for bolts to measure the bolt preload using ultrasonic methods. There are different formulations for these devices such as bolt tension measuring device, bolt load meter or bolt tension gauge. What is meant in any case is the perfect measuring device to improve the accuracy when fastening your bolt connections.
Tightening a bolt creates a tension that causes the bolt to lengthen. This extension can be measured with a stud tension meter, which in turn allows conclusions to be drawn about the tension applied. Our screw tension measuring devices can achieve accuracies of less than 5% of the attached load when measuring connection from 1.27cm up to 30m.
The user takes a measurement before and after a connection is tightened to determine the change in screw length. The measurement data are evaluated using the integrated microcomputer and the time (nanoseconds), the expansion, the charge, the voltage and % load can be shown on the display.
