过去,一般采用通过听音棒或长柄旋凿之类的工具直接用人耳测听的方法,来检查机械的传动部分在运转中是否正常。但是,机械的振动通过这些物体的传递,其能量总要受到一定的损失;而且,这种测听方法的使用范围,也会受到一定客观环境的限制。半导体轴承侦听器能将机械振动信号进行转换和放大,并通过耳塞机发出音响信号。用 In the past, generally through the use of listening sticks or long-handled screwdriver and other tools directly audible listening method to check the mechanical transmission part of the operation is normal. However, the vibration of machinery through the transfer of these objects, the total energy will be subject to a certain loss; Moreover, the scope of use of this audiometry, will also be subject to some objective environmental constraints. Semiconductor bearing interceptors convert and amplify mechanical vibration signals and emit audible signals through the earbuds. use
