ZHANG Gui-xiang, WANG Xiang-ling, HU Fang. Development of the non-contact flange torque measurement instrument[J]. 2010, 29(11): 98-100+103. DOI: 10.13873/j.1000-97872010.11.034.
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.
