摘　　要：介绍了一种基于能量和信号无线传输的高精度扭矩测量仪的工作原理、方案设计和实验结果。通过一组紧耦合环形天线实现能源和信号无线传递,扭矩信号在数字PCM/FM传输基础上利用二次调频技术,显著提高测试精度。该扭矩仪以法兰结构连接,体积小、便于安装、抗干扰性强,实验结果证明:其精度高达0.2%FS。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.
