TensionCam for trouble-free clamp load control
Sufficient clamp load is the critical parameter for a well-working bolt joint in all industrial enviroments. Without clamp load the risks are severe for failure, leakages, break down or human injuries. Up to now there is no reliable, cost effective and easy to use control method available. TensionCam is the answer! It all ends up in trouble-free clamp load control!
Technology
How it works
With the patented TensionCam concept the clamp load is measured by using a special sensor module. It actually includes a fingerprint sensor! Instead of fingerprint patterns the module – when docked to the bolt head – makes images of a precision turned circular pattern in a cavity of the bolt head.
User interface
A TensionCam app is the tailormade user interface for measuring and follow-up. Once you have docked the sensor module the measurement takes place automatically. All measured values are saved on our server and are available in trend diagrams for each individual bolt joint.

Products
Bolt and Washers
Bolts
The TensionCam bolts are basically normal bolts but where a small cavity with the circular pattern has been bored in the bolt head. The cavity is 20 mm in diameter with a 1.7 mm depth. Our assortment ranges from M16 to M68 with various kinds of special designations possible at request. Except for 10.9 and 8.8. bolt material other steel material designations are also available at request. All TensionCam bolts have undergone extensive testing in order to fulfil bearing load characteristics and other life requirements.
Washers & Nuts
The TensionCam nuts & washers are basically normal nuts but where a small cavity with the circular pattern has been bored at three places on the side of the nuts. The cavity is 20 mm in diameter with a 1.7 mm depth. Our assortment ranges from M30 to M68 with various kinds of special designations possible at request. Except for 10.9 and 8.8. bolt material other steel material designations are also available at request.. All TensionCam washers & nuts have undergone extensive testing in order to fulfil bearing load characteristics and other life requirements.

Bolt clamp load is critical everywhere!
There are several reasons for loosing clamp load in bolt joints:
Vibrations, changing temperatures and operation loads are among the most important.
Equally risky is the actual tightening procedure at initial installation. Tightening with some sort of hydraulic or pneumatic torque wrench there is a large uncertainty on how much of the specified torque that are actually resulting in axial clamp load. The uncertainty is coupled to the friction in the joint.
All in all, monitoring and control of the actual clamp load at installation and during the life of the bolt joint is needed to guarantee its’ intended functionality.
