Custom Shaft Torque Sensor Solutions

We also offer Rotary Power Sensors, Rotary Torque Sensors and Torque Meters that are capable of measurements above our standard range of 20,000Nm to meet the needs of our customers within a commercial environment.

Custom Shaft Torque Sensor Solution and Shaft Power Meter

Our standard torque sensor range incorporates the measurement of torque up to 60,000Nm,  these provide solutions to most test and monitoring requirements

Our custom shaft torque sensor solutions open up opportunities to incorporate torque sensing into existing machinery or test rig designs without changing the drive line. A custom sensor reduces the cost of changing couplings and machinery positions, they also maintain the dynamic of the drive system improving test results. We design and manufacture custom torque sensors capable of measuring from 2 Nm up to 40 MNm. Over the last year, Datum Electronics have made small torque sensors to fit sensitive handling equipment and the world’s largest ever torque sensor.

A custom shaft torque sensor can improve test rig design and machine, therefore, we design torque sensors that replace existing drive shafts and couplings. A custom torque sensor saves time and cost of adapting drive lines. Sensors can be delivered in surprisingly short time frames often faster than the time spent adapting to a rig.

All of Datum Custom Torque Sensors use our well-proven Series 425 and 426 electronics which provide high levels of accuracy and resolution. These products are used as Rotary Torque Transducers, Reaction Torque Sensors, and Digital Torque Meters.

Rotary or static applications, shaft trials or telemetry systems, custom shaft torque sensor solutions engineered to fit of free issue couplings, whatever your requirements Datum Electronics have the expertise and experience to offer the right torque measurement solution at a competitive price.

Here are just a few examples of fully custom torque sensors we recently designed and supplied for torque measurement application in a number of industries, including defence, marine, oil and gas, robotics, machine building and mixing industries.

Torque Sensor M420 Size 5 Addition To The Range 0-20,000Nm


This  M425 digital rotary torque sensor Size 5  was supplied with a 2-meter shaft and splined end fittings to replace a customer’s test rig drive shaft. The torque measurement range was 0-40,000Nm, this system provided a complete solution and saved the cost of a complete test rig re-design.


Flange 200 kNm

This bespoke 250KNm rotating torque sensor for a winch test rig was configured with parallel ends and sized to fit existing compression couplings.


50000Nm Coupling Spacer Sensor


This custom Dual Flange Non-Contact FF425 Torque Sensor, capable of measuring torque of 0-40,000 Nm.  A number of these torque transducers was manufactured to replace existing coupling spacer, used between motors and pumps with a power station. The couplings were designed to operate up to 4000 rpm.

Product Used As Rotary Power Sensors



We designed and supplied this Custom Shaft Torque Sensor to fit onto a coupling in a cement mixer drive. This custom shaft torque transducer was manufactured from the existing components and saved the customer the cost of moving the gearbox to make room for a standard torque transducer.

Product Used As A Rotary Torque Sensors | Custom Torque Sensors
Datum Electronics manufactured a custom torque transducer, designed to measure torque of 0-270,000Nm, replacing an existing drive coupling spacer on a customer’s test rig.

Custom Engineering Solutions


One of our customers used this custom drive shaft torque meter design was used for heavy vehicle trials.


Static And Rotary Torque Transducer FF425


Based on the standard FF425 Torque Transducer, we have made many units with custom flanges and end fitting to suit our customers’ requirements.


60KNm Custom Shaft Torque Sensor | Dual Flange Torque Transducer

A larger version of the FF425 Series of digital rotating torque sensor, that only has a partial stator, has been designed to replace heavy drive line components. The latest of these was capable of measuring torque up to 12,000,000 Nm.

Product Used As Torque Meter



A bespoke Military adaptation of our MIL Spec and DefStan Approved Shaft Power Meter System, designed for a naval shaft power measurement application. These systems have been adapted for very harsh marine environmental conditions and are successfully used in industry and on ships today.


Custom Shaft Torque Sensor from 2Nm up to 40 MNm

  • We offer a range of Torque Transducers and Torque Sensors that are capable of torque measurements above our standard range of 60,000Nm
