摘要

介绍了一种用InSb-In共晶体薄膜磁阻元件制作而成的液体开关。此种液体开关是利用液体流动时的冲击力推动置于液体管道中的涡轮转动。该涡轮由磁钢材料制作

当转动的涡轮叶片靠近InSb-In共晶体薄膜磁阻元件时引起其阻值的变化

进而产生交变信号。经过对信号的处理

最后送入单片机进行计数

当脉冲频率低于某一设定值或高于某一设定值时

通过单片机输出高电平

起到报警的目的。本流量开关是基于四分管设计

其监测的流量范围为1.5

.4 L/min。

Abstract

A flow switch made by InSb-In eutectic film magneto resistor is introduced.When liquid flows in a pipe

the drag force will impulse the magnetic element to rotate.InSb-In eutectic film magneto resistor will change correspondently.At the same time

the AC signal also can be obtained and sent to a microprocessor.The microprocessor will output high level and give an alarm when pulse frequency exceeds the limitations.The detection range can be set freely between 1.5L/min and 8.4L/min.
