Rotary Torque Transducer Type M425

Torque Sensors 5Nm to 60,000Nm
The latest technology Datum Electronics Series M425 non-contact rotary Torque Sensors have been designed to fit with most applications and solutions requiring rotary torque and power measurement. The Torque Sensor fits in line with the drive train or test bed, using standard keyway shafts.
Torque Measurement DataThe M425 represents a quantum leap forward for anyone looking to measure torque and power with high accuracy and repeatability using up to 24bit resolution.  
The M425 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
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 the M425 becomes the simple choice for anyone looking to use torque, speed and power measurement system.
Torque Sensor Interface
The M425 Sensors have 14 standard torque ranges. With the high resolution of the M425 and the correct range the Sensors will offer resolution and accuracy across the complete range from 0 to 60,000Nm. The torque ranges start from as little as 0-10Nm up to 60,000Nm.

Torque Sensors and Torque Transducers
A non-contact transmission system provides data directly proportional to torque. In this variant it is supplied as a complete transducer with bearings to support the stator unit on the rotating shaft. It is suitable for most general test rig applications.
The M425 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 M425 has a torque measuring element design with an optimum length to maximise overall accuracy and give a high degree of tolerance to mounting offset.
The M425 also has a legacy mode so that it can be used as a direct replacement for the previous M420 Transducer.
Benefit from both the high specification and competitive torque sensor pricing
