The dynamic torque measure system based on RF
technology can be realized by the dynamic torque sensor
and RF receiver circuit. Application of 2.4GHz RF
technology to the dynamic torque signals transmission is
better to achieve noncontact dynamic torque measure.
Compared with the traditional system whose signals are
transmitted by slip ring, the RF transmission system has
higher accuracy, longer service life and wider applications
in the future. The dynamic torque measure system based
on RF technology has a good application prospect.
