对旋转机械的转轴进行在线监测,一般都采用非接触式位移传感器。非接触式位移传感器是基于电涡流原理设计制造的,整个系统是由探头、延伸电缆和前置器组成的一次仪表测量系统。最近,德国申克公司推出了一种新型传感器VIBRONECS,其设计思想是采用混合集成电路的方法,把延伸电缆和前置器的功能用一块电子线路板代替,和探头线圈封装在一起,
On the rotary shaft of the rotating machinery for online monitoring, are generally used non-contact displacement sensor. The non-contact displacement sensor is designed and manufactured based on the principle of eddy current. The whole system is an instrument measuring system composed of a probe, an extension cable and a front device. Recently, Germany Schenck introduced a new type of sensor VIBRONECS, the design idea is the use of hybrid integrated circuit method, the extension cable and the pre-function with an electronic circuit board instead, and the probe coil package together,
