The principle

design and test results of a high-precision torque measurement instrument based on energy and signal wireless transmission are introduced.The same group of tightly-coupled loop antennas is shared to achieve energy and signal transmission

the use of quadratic FM signal transmission technology based on PCM/FM improves test precision.The torque instrument has unique connection flange structure

small size

easy to install

and strong anti-interference property.Experiments prove its precision is as high as 0.2 % FS.
