基于ADμC812的专用超声波液位传感器

针对易燃、易爆化学物质储罐内液位及相关量难检测的问题,基于ADμC812 芯片设计了一套用于远距离、大量程、非接触检测的超声波液位传感器。该传感器具有自增益、可编程和扩展性能好等优点,可以检测所有沸点高于储存温度的介质液位,对其它同类传感器的远距离检测及智能化实现有良好的参考价值。

Abstract : According to difficult measurement of combustible explosive chemic2substance liquid2level and correla2 tive quantity ,a set of ultrasonic liquid2level sensor based on ADμC812 chip for far2distance ,large2range and non2 contact liquid2level measuring is designed. The sensor has the advantage of  elf2plus ,programmable ,fine expansi2
bility ,which can measure the liquid2level of all mediums whose boiling point is higher than deposited tempera2 ture. It has well referenced value on the intelligentized realization and far2distance measuring of other analogous sensor.
