M425 INTRODUCTION
What is it designed to do?
The latest technology Datum Electronics Series M425
non-contact rotary Torque Transducers have been designed
to fit with most applications and solutions requiring rotary
torque measurement. The Torque Transducer fits in line with
the drive train or test bed, using standard keyway shafts.
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.
