常用的霍尔传感器有三种:常开型、常闭型、自锁型,这三种传感器不能混用.我厂生产的拉丝机,就使用霍尔传感器与计数器组合成计数器(见图1),以测量显示拉丝长度,实现自动停车.这里所用的霍尔传感器是常闭型的.常闭型霍尔传感器应用最为广泛.如果选用常开型的,虽然有计数器的计数功能,但易受外界干扰.其表现为;其它电器的闭合与关断,甚至电哦
Hall sensors commonly used in three ways: normally open, normally closed, self-locking type, these three sensors can not be mixed with my factory production of wire drawing machine, the use of Hall sensors and counters combined into a counter (see Figure 1) To measure the length of the wire drawing to achieve automatic parking. Hall sensors used here are normally closed. Normally closed Hall sensor is the most widely used. If you use the normally open type, although the counter counting function, but vulnerable to the outside world Interference. The performance of other electrical appliances closed and shut down, or even electricity oh
