Custom Industrial Torque Sensors
Datum Electronics are able to provide both modular and custom designed torque and rotary strain measurement solutions, which can be complete as one off or as fully integrated OEM solutions.In many cases, it is better to use an existing shaft or test rig and use custom industrial sensors instead. This process reduces the cost of fitting a conventional torque transducer and it improves the torque measurements, taken by maintaining the dynamics of the driveline.

Shaft Power Measurement Solutions
Our marine shaft power meter systems measure shaft torque, power, propulsion, rpm and thrust (if required), to ensure optimum performance is maintained throughout the lifecycle of a vessel. Using highly accurate & reliable strain gauge technology, combined with cutting-edge electronics, our system has an accuracy of 0.1%. It can be installed and commissioned within 1-2 days on a variety of shafts including intermediate shafts, thrusters, propellers and controllable pitch propellers. Our technology, along with our expertise in dynamic sampling of strain gauges, enable us to unlock a significant amount of information regarding the performance of the engine & propulsion shaft, along with the propeller.
