Class 1-2 Torque Tool

Class 1-2 Torque Tool has been specifically developed to provide the highest level of performance. It has integral torque and turns counting sensors. When matched with a NOR supplied torque tool control manifold, the Class 1-2 Torque Tool can provide precise feedback on torque response of any subsea operation. These can alternatively be utilized by con­necting a Universal Subsea Display, which would give a visual read-out of live torque feedback and turns count.

The tool conforms to the ISO 13628-8 Class 1 and 2 bucket interface used extensively in the subsea industry for valve overrides operated by ROV. The tool can also be supplied with a socket to operate paddle and t-bar style interfaces to ISO 13628-8. The sensor section directly measures the torque between the reaction lugs of the tool and the driven shaft. The sensor is a strain gauge bridge optimized for torsion measurement. When the Class 1-2 Torque Tool is fitted with the paddle type socket, the torque reaction is taken through the manipulator handle but still measured by the sensor.
