一、概述本仪器广泛适用于各种动力设备的非接触在线扭矩测量。例如,轮船螺旋浆、航空发动机推进器、石油钻机和各种机床主轴扭矩的测量等。该仪器由两大部分组成:一部分是一种新型的磁弹性传感器,这种传感器近年来在国外越来越受到重视并获得相当成功的应用。它的优点在于传感器做成空芯套简式,套筒的直径可视被测轴径尺寸而定。传感器直接套在测试轴件上(但不接触),进行非接触测量,在设备运行状态下可方便地获得扭矩参数。而国内目前生产的磁电式、光电 I. Overview This instrument is widely used in a variety of power equipment non-contact online torque measurement. For example, the ship propeller, aircraft engine thrusters, oil rigs and a variety of machine tool spindle torque measurement. The instrument consists of two parts: one is a new type of magnetoelastic sensor, which has gained more and more attention abroad in recent years and has been used successfully. Its advantage is that the sensor is made of hollow core sleeve, the diameter of the sleeve can be determined according to the diameter of the tested shaft. The sensor is placed directly on the test shaft (but not in contact) for non-contact measurement, allowing easy access to torque parameters while the unit is in operation. The current production of magnetoelectric type, photoelectric
