When a standard bolt is tightened, the tension achieved is completely unknown, RotaBolt load indicating fasteners are measuring devices and highly accurate indicators of clamping force or tension. How does it work? Achieving and maintaining the correct clamping force, or bolt tension, is essential in assuring bolted joint integrity. 85% – 90% of all bolted joint failures are caused by insufficient bolt tension. Why does it work? Over 90% of all bolted joint failures can be attributed to low bolt tension on installation tightening. Achieving and maintaining the correct installed design tension will eliminate failures. Where does it work? RotaBolt load indicating fasteners are in use around the world to provide leak free joint integrity or assure structural stability in applications subject to vibration, pressure or thermal cycling. RotaBolt-TD The RotaBolt-TD system is the first system in the world to give genuine remote and wireless monitoring of bolted joints Monitor bolted joints on the other side of the world from a mobile phone The RotaBolt-TD system continuously monitors and reports in-service bolt tension by SMS or email. RotaBolt-TD is supported with state of the art instrumentation and data automation, and can be deployed with a full data management and reporting package. Each bolt in the RotaBolt-TD system contains micro instrumentation and a wireless transmitter. It periodically reads bolt tension, critical to the integrity of the joint, and then wirelessly transfers the information to a local transceiver which collects the data from any number of bolts and then transmits the report via the internet, or GSM network, to a secure server. Each bolt contains a coin-cell battery which ensures 5 years continuous unattended operation. The system has been developed by James Walker RotaBolt, world leaders in bolted joint technology, and Transmission Dynamics who design and manufacture wireless telemetry and data acquisition systems for recovering in-service load information from the most demanding of environments. Watch the Rotabolt TD video Our Products RotaBolt load indicating fasteners are bolts and studs that allow a specific tension to be applied Rotabolt 1 A standard bolt is converted with a RotaBolt and RotaCap. Component materials are compatible to nullify in-service thermal and galvanic effects. RotaBolt 2 RotaBolt 2 provides an even greater range of tension control on installation tightening and in-service checking, by offering two tension settings. RotaBolt-TD The RotaBolt-TD system is the first system give genuine remote and wireless monitoring of bolted joints from anywhere in the world. RotaBolt Vision Using the same air-gap technology, Vision has a specially developed indicator which appears as an yellow line across the head of the fastener.
