M425 In-Line Rotary Torque Sensor | Torque Trasducer

The M425 In-Line Rotary Torque Sensor also gives the customer control over their tests with torque sample rates selectable at any time from 1sps up to 4000sps as standard. With rpm measurement based on up to 30 pulses per revolution, the M425 is now the complete torque transducer for measuring torque and power on any rotating shaft.

When paired with the Datum Universal Interface (DUI), the M425 gives customers a digital display of torque, speed and power plus a complete range of both digital and analogue outputs. The digital outputs include; Ethernet, RS485 and USB as well as local logging of test data to a USB memory stick. The DUI has 4 programmable analogue channels which can be selected from 0-20mA, 4-20mA, +/-10Vdc, +/-5Vdc, 0-10Vdc, 0-5Vdc for the output of torque, rpm, power etc. Using the DUI, an M425 rotary torque sensor becomes the simple choice for anyone looking to use torque, speed and power measurement system.

FF425 Non-Contact Flange Torque Sensor | Flanged Torque Transducer

The FF425 Flange Torque Sensor can either be supplied from our standard range with DIN flanges up to 30KNm or as custom units up to any size with the flange and length dimension designed to fit with an existing coupling spacer design. With the custom option drive lines can have a torque transducer integrated with a minimum of cost and disruption or need to find additional space.


The FF425 is a true non-contact torque transducer, the rotor runs inside the stator with a 2 to 5mm air gap. This ensures no long- term wear of bearings or frictional loads on the rotating drive shaft.



The FF425 Torque Transducers are ideal for test rigs and permanent machinery applications.

RS425 Completely Bearingless Torque Transducer| Torque Sensor

The RS425 bearingless torque transducer utilises a strain gauged shaft for accurate and reliable torque measurement and a set of rotating on shaft conditioning electronics, the digital signals are transmitted to the non-rotating part of the system or stator providing a reliable and highly accurate torque measurement solution. The rotor is continuously powered enabling static torque measurement to be made. Not only does the RS425 Series offer great technical advantages but the range of torque sensors are competitively priced. 


The RS425 series torque transducer is not limited by bearings; therefore, it can be used at higher speeds, and places no bearings loads on to the shaft. The stator needs to be mounted in relation to the shaft within an operating envelope of +/- 3 to 5mm. The standard range can measure torque ranges from 0-10Nm up to 30kNm, the same modular elements have been applied to bespoke torque transducers for use down as low as 3Nm and up to 500kNm and above.

Series 460 3-Hole Bolt-On Sensor | Weighing Sensor | Strain Measurement

Datum Electronics offer two types of multi-element bolt-on strain gauge sensors that have been developed to provide a rugged and robust production sensor with the benefits associated with a complex strain gauge installation.

The gauges have been designed for use in applications including vehicles, civil engineering structures, silos, hoppers and specialist engineering projects. They have been designed to measure tensile and compressive bending stresses ranging from 50 to 1100 micro-strain.

The 3-Hole bolt-on strain gauge sensor has a unique design eliminating the temperature effect on bending and strain of the application, providing a far more effective strain indication than a standard 2-hole option.

Our Bolt-on Strain Gauge Weight sensors are quick and easy to install without any fine wiring or soldering. Its practical robust design allows the sensor to work in almost any environment, in any weather and even underwater if required. Rated to IP68 this is a truly universal product that will give you reliable accurate strain indication whatever the application or environmental condition. All sensors are pre-tested and checked during final assembly ensuring the reliability and quality of all our sensors.
