The Datum Series 420 Naval Torsion Meter System is a precision-engineered solution trusted by the Royal to monitor and optimise propulsion system performance. Designed to measure shaft torque and power output with exceptional accuracy, this advanced torsion meter enhances operational efficiency and ensures the reliable performance of naval vessels. Built to withstand the demanding conditions of maritime environments, the Datum Naval Torsion Meter offers real-time data analysis, enabling proactive maintenance, fuel savings, and improved overall fleet performance. With its robust design and cutting-edge technology, it has become an indispensable tool for modern naval engineering.
The Datum Naval Torsion Meter is a modular system that is currently supporting both surface and subsurface platforms for the UK Navy. The flexible modular design allows this to be used in a variety of shaft line configurations for any number of propeller shafts and any size shaft diameter.
UK MOD and USA MIL Spec Tested
Our naval ship monitoring system assesses and monitors propeller shafts on ships, by measuring torque, shaft power, direction of rotation and output shaft power. The Datum Naval Torsion Meter is one of
the few MIL-SPEC and Def Stan systems in the world.
As the supplier of choice for BAE Systems and Babcock International, Datum Electronics has a long-standing history of supporting the Royal Navy, including platforms such as the Hunt and Sandown class minesweepers, and the Astute and Dreadnought class submarines. Our systems have also been deployed across a range of naval platforms operated by the Australian, Indian, and South Korean navies.
The ship propeller shaft power meters have been through rigorous UK MOD and USA MIL testing programmes for the harshest of environments, and are therefore verified in a number of marine conditions, including:
- MIL Spec std. 901-D shock
- 167-1A 2005 Vibration
- Safety Case to JSP430
- Shock to Def Stan 08-120
- EMC to Def Stan 59-41
- Selection of Marine Torsion meters Def Stan 02-606
- Magnetic Ranging to 08-123 DS31
- IEC 61508 compliant option
