Key Features

The FF425 rotary 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.

Using our revolutionary new electronics as used in our industry standard, our M425 inline rotary torque sensor,  the FF425 gives customers higher resolution with up to 24bit resolution and the ability to choose their sample rates from 1 up to 4000sps.

FF425 Flange Torque Sensor Features

The FF425 non-contact rotary flange to flange torque sensor has 11 standard torque ranges. The torque sensor offers very high accuracy, operational stability, high signal resolution and wide range of signal outputs across the whole range of torque from 0-100Nm and up to 30,000Nm.

I just wanted to thank you for the excellent service. The torque flange has arrived to our facility. If I could get such service and lead times from the rest of the supply chain, it would make life easier.

The FF410 Static/Reaction Torque Sensor Range

If you’re looking to measure static torque? Then the Datum Electronics Series FF410 Reaction torque sensor with standard DIN flanges will be an ideal and cost-effective choice. This static torque sensor was based on our FF425 series of rotary torque transducers and is used to measure torque with no rotation or angular acceleration. As in the FF425 Flange to Flange Torque Sensor range, FF410 Reaction transducer design uses the same basic shaft components and cutting-edge strain gauge technology, allowing us to keep the reaction torque transducer competitively priced with a high torsional stiffness included.

Easy Fit into Drive Train

The 410 Static Non-Contact Torque Transducer and FF425 Flange to Flange Rotational Torque Sensors easily fit into your existing test rig, test bench or drive train. Using standard DIN flanges, fitting and coupling, the FF 425 dynamic torque sensors and FF110 static torque transducers are made more efficient than other options available. The minimum operating envelope of the Datum flange to flange torque meters starts from 100mm and will increase depending upon torque measurement requirements.

 

Benefits

      FAQs

    • how can I measure accurate power in my test rig when there is no room to add an inline transducer?

      You can use existing components to become an accurate inline torque transducer, Datum Electronics FF425 transducers are a range of flanged coupling spacer transducers that can replace your existing coupling spacers and give you real time accurate Torque, Speed and Power data from our standard range.  Our specialist team can even work with you and the existing spacers that you have and turn these into Torque Transducers.  With Datum Connect you can use your smart phone or smart device to wireless view and log accurate Torque, Speed and Power seamlessly.

    • How can I work out the Torque for my test, I only have the Motor Speed and power?

      Datum Electronics Ltd can work with the customer to calculate the expected torque using known measurement principle and suggest an appropriate torque sensor for you like our M425`

    • What if I don’t know my maximum torque measurement load?

      Datum Electronics torque sensors have a safety factor built into them for 150% overload protection. Our technical sales team will be happy to work with you to help you choose the right sensor

    • What is the smallest torque that you can measure?

      Our standard RS425 Size 1-Al is a 0-3Nm transducer which will give an accuracy of better than 0.1% of the full scale allowing for measurement in the Ncm range.
