针对在电火花加工放电位置检测仪中传感器系统设计方面存在霍尔传感器输出的原始信号幅值微弱的问题,采用将霍尔传感器嵌入在长方体铁氧体材料中组成传感器系统的方法,使原始微弱信号幅值增大了1000倍。 Aiming at the weak original signal amplitude of the Hall sensor output in the design of the sensor system in EDM discharge position detector, the method of embedding the Hall sensor in the rectangular ferrite material to form the sensor system is adopted to make the original weak Signal amplitude increased 1000 times.
