电阻应变式转矩转速测量仪

An Instrument with Resistant Sensor for Torque and Speed Measurement

本文详细介绍了电阻应变式转矩传感器的结构特点和工作原理。它采用旋转高频变压器为电桥和旋转电路供电，采用光电耦合元件传递转矩信号，克服了用滑环和电刷供电产生的困难，消除了用滑环和电刷传递信号造成的误差。利用单片机进行数据处理，使转矩转速测量更准确。

This paper presents the structure and working principle of a resistant torque measurement instrument. The data are processed with a single chip microcomputer, which makes the measurement more accurate, and makes it easy to realize automation of the measurement.
