RotaBolt® 3 has been designed and developed to provide continuous tension monitoring; it can also provide control of the applied tightening system.
As soon as any tension is lost across the bolt, the indicator instantly rotates by 90 degrees to show a distinct right angle break in the yellow line.
It incorporates a built in, electronic tension sensor which can be hard wired to give the operator continuous feedback and monitoring across the joint. Alternatively, it can be used with a hand held monitor. A wire-less version using telemetry is currently being developed.
