Installation of second Continuous Duty (CD) torquemeter SIL2 system

Torquemeters is pleased to announce the completion of the commissioning on a further SIL2-rated continuous duty torquemeter, this time for Total’s facility in Feyzin. Torquemeters pioneered the first such system, in collaboration with Total, for the Total Refinery Antwerp site in 2017. The system allows the safe operation of an upgraded compressor installed on an existing steam turbine and the torquemeter provides real-time performance data ensuring optimal operation whilst avoiding an overdrive/overload event which would potentially damage the newly installed equipment. To use shaft horsepower as a control function on steam turbines, the Torquemeter TorSil product is unique. Speed of reaction to enable the control system to operate without the need for complicated calculations involving head pressure, water/steam quality, flow and temperature is simplified using a standard torquemeter and is made Functionally Safe using the 2oo3 voting TorSil variant. In addition to providing normal Condition Monitoring data on shaft horsepower (trending, washing cycle needs, direction of fouling information), the customer now has an automated system with SIL 2 which provides a system needing no user intervention, other than that required for SIL 2 (a scheduled functional test at shutdown). This releases plant man hours for other duties and ensures continued, safe plant operation.

Key features of the installation includes;

  • SIL2 protection rating
  • No rotating electronics
  • Ability to compensate for changes in environmental conditions
  • High degree of reliability and accuracy
  • 9Long service intervals and low maintenance requirements
  • Optimisation of turbine/compressor performance during commissioning

Torquemeters awarded a major new test rig contract for the UK Electrification of Aerospace Propulsion Facility (UKEAPF) based within the University of Nottingham’s new Power Electronics and Machines Centre.



Torquemeters are pleased to announce that they have been selected for the award of a major new project from the University of Nottingham to provide a unique, fully instrumented, 2MW 30,000rpm dynamometer test stand for e-motors & generators for hybrid electric propulsion systems within the Power Electronics and Electrical Machines Centre.

The dynamometer will be designed to enable testing and validation of MW- and kV-class electrical drive systems for both low-speed (800-6,000rpm) as well as high speed (15,000-30,000rpm) applications. The fully instrumented dynamometer will enable the validation of innovative electrical machines in real operating environments including the ability to apply static and dynamic torque and axial thrust profiles. The Power Electronics and Electrical Machines Centre at the University of Nottingham will host this test system to support extensive development programmes in aircraft and other transport electrification. The dynamometer will also be made available to the wider industry.

The project commenced in April 2021 and is expected to conclude early next year with the fully commissioned rig available for testing at Nottingham by the end of February 2022.

Geoff Robinson, Sales Director for Torquemeters Limited commented, “The UK Electrification of Aerospace Propulsion Facility is a key steppingstone to enable the realisation of the next generation of low carbon e-propulsion systems. We’re very excited at Torquemeters to be supporting the team at the University of Nottingham with this initiative, building on the long-term relationship between the two organisations and look forward to supporting the respective engineering & operational teams as they execute this flagship project.”

Torquemeters awarded UKAS accreditation for torque and phase calibration to ISO/IEC 17025.



Following an extensive qualification programme, Torquemeters Ltd calibration laboratory in Ravensthorpe has been granted UKAS accreditation against the requirements of ISO/IEC 17025:2017 – General requirements for the competence of testing and calibration laboratories.

This accreditation is based on Torquemeters Ltd ability to conduct torque and phase calibrations to a high degree of accuracy for incorporation into precision torque measurement devices.

Torquemeters use a qualified purpose-built torque calibration rig to conduct torque calibrations to BS7882:2017 or DIN51309:2005, designed to give the best certification capability and the lowest uncertainty of measurement. Balanced arms are supported by low friction bearings with the torque transmitted via flexible couplings to prevent end loads and moments being applied to the article under calibration. The reaction arm can be levelled to ensure the load arm is always horizontal and calibrated masses are used to give minimum uncertainty for all load conditions. The environment is controlled, and calibrations are conducted by qualified technicians to ensure quality and consistency of calibration and service. The calibration rig torque capability range is 300-3500 N∙m with uncertainty in applied torque better than 0.01% (k=2 for a probability of 95%).

Torquemeters’ accredited laboratory can also undertake calibration of phase meters. Units under test are assessed against calibrated waveform generators, reporting deviations at a range of phases and frequencies. Accredited ranges include phase angle or % phase measurement for amplitudes of 50mV rms and 500mV rms at frequencies up to 100kHz.

Over the past 70 years, Torquemeters has been responsible for the innovation of the first phase-shift torquemeters, now widely used both for testing & development within the aerospace industry. With this significant investment in the new calibration equipment and the successful conclusion of the year-long qualification programme, Managing Director, Ben Van Millingen, commented “We’re very pleased to have met the stringent requirements for UKAS accreditation, which has been a long-term ambition for the business, and underpins our commitment to supporting our customers’ needs for highly accurate torque measurement within their development testing programmes.”
