线性接近传感器的原理是属于金属感应的线性装置在接通电源时将在传感器的传感表面上产生交变磁场。当金属物体接近传感表面时,在金属中产生涡电流并且振荡被吸收。振荡器的能量线性地衰减振荡器输出的幅度,然后基于衰减的变化执行对象的非接触式检测的目的。
The principle of linear proximity sensor is that the linear device which belongs to metal induction will produce alternating magnetic field on the sensor surface when the power supply is switched on. When the metal object approaches the sensing surface, eddy current is generated in the metal and the oscillation is absorbed. The energy of the oscillator linearly attenuates the output amplitude of the oscillator, and then performs the non-contact detection of the object based on the attenuation variation.
接近传感器没有滑动接触,并且在操作期间不受诸如灰尘的非金属因素的影响。长寿命功耗可在各种恶劣条件下使用。
The proximity sensor has no sliding contact and is not affected by non-metallic factors such as dust during operation. Long life power consumption can be used in various harsh conditions.
