一、传感器的简单原理电磁式速度传感器(图1)由线圈和永久磁铁组成。当线圈与气隙磁场发生相对运动时,线圈切割磁力线而产生出运动电势,线圈的运动通过线圈连接端部的小球头与胶粘在振动体被测点上球头座,由两端带弹簧卡头的连杆把这两者相连,使传感器直接感受振动,引起线圈的上下运动,感应量为振动速度。线圈在磁场
First, the simple principle of the sensor Electromagnetic speed sensor (Figure 1) consists of a coil and a permanent magnet. When the coil and the air gap magnetic field relative movement occurs, the coil cutting magnetic lines and produce a moving potential, the coil movement through the coil connecting the end of the small ball head and the adhesive in the vibrating body ball point seat measured by the two ends of the belt The connecting rod of the spring chuck connects the two so that the sensor can directly sense the vibration, causing the coil to move up and down, and the sensing amount is the vibration speed.
