本文介绍的数字式扭矩仪由扭矩传感器和数字显示仪表组成,扭矩传感器是用磁电检测器检测扭轴的扭转变形的装置,数字显示仪表能对传感器输出的电信号进行处理,直接显示出扭矩读数。文中主要讲述这种扭矩仪的工作原理、结构特点及标定方法。 The digital torque meter introduced in this paper consists of a torque sensor and a digital display instrument. The torque sensor is a device that detects the torsional deformation of the torsion shaft by using a magnetoelectric detector. The digital display meter can process the electrical signal output by the sensor and directly display the torque reading. The paper mainly describes the working principle of this torque meter, structural characteristics and calibration methods.
