摘要
皮带运输机是矿山运输的重要设备,低速保护是其重要的保护指标之一。利用霍尔效应制作的霍尔开关元件无触点、无磨损、故障率低。与传统的测速机构相比,霍尔转速传感器制造简单,成本低,精度高、线性度好,经济性能好。
Belt-conveyer is the important equipment in mine transportation, and the lower-speed protection is one of its significant measures. The switch utilizing Hoer＇s domino effect has no crossing-dot, no abrasion and lower malfunction. Compared with the traditional speed-measure facilities, Hoer＇ s rev-sensor has the advantage of easiness in making, lower-cost, high precision, and excellence in linearity and economy.
