Digital Torque And Rotational Speed Sensor And Its Application In The Turning Machine

本文介绍了JN338数字式转矩转速传感器,该传感器使用了两组带间隙特殊环形旋转变压器,实现了能源及信号的非接触传递,其信号输出为数字量,便于和微机接口。文中对传感器的工作原理及特性予以了详细介绍,并给出了在旋转动力装置机械参数测试中的一个典型应用示例。

The JN338 digital torque and rotational speed sensor are introduced. Using tow suits special circumrotating transformer with clearance, the sensor can transfer energy and signal without contact, and the digital signal output makes it easy to meet with microcomputer. The principle of work and characteristics of the sensor are particularly presented in this paper, and a typical appliance demonstration that the sensor was used to test the parameters of rotatory dynamical set is given.
