What our customer say about us
How can preload be measured?
Via ultrasonic transducers
The measured variable “ultrasonic time-of-flight†increases with elongation. Very good accuracy, no modification of the joint and easy to measure.
With strain gauges
Preload measurement with strain gauges are accurate but expensive in preparation, lead-time and installation. (principle: measuring the stress inside or outside of the bolt)
Via elongation
Preload can be calculated at low-cost by measuring elongation with mechanical or optical tools but with limited accuracy and repeatability.
