針對易燃、易爆化學物質儲罐內液位及相關量難檢測的問題,基于ADμC812 芯片設計了一套用于遠距離、大量程、非接觸檢測的超聲波液位傳感器。該傳感器具有自增益、可編程和擴展性能好等優點,可以檢測所有沸點高于儲存溫度的介質液位,對其它同類傳感器的遠距離檢測及智能化實現有良好的參考價值。

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.
Key words : liquid2level sensor ; ultrasonic ; far2distance measuring ; large2range
