Product Description

The latest technology Datum Electronics Series non-contact rotary Torque Sensors have been designed to fit with most applications where the measurement of accurate rotary torque and power measurements are required. The M425 Rotary Torque Sensor fits in line with the drive train or test bed, using standard keyway shafts.

The Datum M425 Rotary Torque Transducer represents a quantum leap forward for anyone looking to measure torque and power with high accuracy and repeatability using up to 24 bit resolution. The M425 torque sensors give 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 the ideal torque transducer for measuring torque and power on any rotating shaft.

M425 Rotary Torque Sensor Range

The M425 Sensors have 14 standard torque ranges. With the high signal resolution and a wide frequency range, the M425 non-contact rotary torque sensor is ideal for measuring torque from 10 to 60,000Nm. Having a torque measurement design with an optimum length to maximise overall accuracy and give a high degree of tolerance to mounting offset, the M425 digital torque sensor is suitable for most general test rig applications, like electric motor testing, pump torque testing, gearbox texting (to name just a few).

A non-contact transmission system provides data directly proportional to torque. In this variant, it is supplied as a complete torque transducer with bearings to support the stator unit on the rotating shaft. It is suitable for most general test rig applications.

The M425 Non-Contact Rotary Torque sensor 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. As all of the analogue signal conditioning is completed within 25mm of the strain gauges the M425 Dynamic Torque Sensors are very stable when subjected to temperature variations and electrical noise.

The M425 rotary torque transducer 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 Ultimate Torque Sensing Solution

When paired with the Datum Universal Interface (DUI), the M425 Torque Sensor 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, and shaft 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.
