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.

Bolt-On Strain Sensors
Datum Electronics bolt-on strain sensors are an ideal solution to many strain measurement requirements. They are robust, dust & water resistant, suitable for the harshest of environments, including high-stress level applications.Bolt on strain gauge sensors are compact in size, can provide temperature compensation (see out 3-hole bolt-on sensors) and have been designed to be easily installed without soldering or gauge adhesive.

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.

Wind Turbine Condition Monitoring
It has also become increasingly apparent in recent years that the wind turbine industry has recognised the importance of condition-based monitoring, especially for offshore wind turbines, where access is often limited.To increase reliability and minimise down time, many wind turbine manufacturers, owners and operators are turning to condition-based monitoring systems, aimed at predicting wind turbine maintenance issues, so that operators can quickly and effectively carry out predictive maintenance, repairs and replacements of components when needed, without the need for costly routine maintenance checks and visits. As a result, a condition monitoring system increases operational time, improves site performance and reduces maintenance costs for wind turbines, especially offshore ones.
