TensionCam sensor
How it works
With the patented TensionCam concept the clamp load is measured by using a special sensor module. The module actually includes a fingerprint sensor! Instead of fingerprint patterns the module – when docked to the bolt head – makes images of a precision machined pattern in a cavity of the bolt head.
For special applications TensionCam washers or nuts can be used. Here the machined pattern is turned on the side face of the washer or the nut.
