1.霍尔效应位置传感器这种传感器探头的端面是一个有相应外形的永久磁铁或电流激励的电磁铁。该端面拥有一个霍尔效应集成电路(HF-IC 电路或霍尔片)。当探头放置在一个铁磁体表面附近(即被测对象附近)时,由下列公式可获得一个霍尔电压:V_H=KI_cB/t=K_HI_cB(1)式中 t——霍尔片的厚度
1. Hall effect position sensor The end of this sensor probe is a corresponding shape permanent magnet or current excitation electromagnet. The end has a Hall-effect integrated circuit (HF-IC circuit or Hall film). When the probe is placed near a ferromagnetic surface (ie, near the measured object), a Hall voltage can be obtained by the following formula: V_H = KI_cB / t = K_HI_cB (1) where t--
