工作原理:

超高溫型射頻導納料位開關是通過(guo)探(tan)(tan)頭(tou)感(gan)知其(qi)與(yu)儲(chu)罐(guan)體間(jian)(jian)電(dian)(dian)(dian)(dian)(dian)抗（容抗和阻(zu)抗）的(de)(de)(de)(de)(de)(de)變(bian)化(hua)(hua)實現物位(wei)測(ce)(ce)(ce)(ce)(ce)量(liang)(liang)和控制的(de)(de)(de)(de)(de)(de)。其(qi)內(nei)部電(dian)(dian)(dian)(dian)(dian)子單元，由(you)探(tan)(tan)頭(tou)測(ce)(ce)(ce)(ce)(ce)量(liang)(liang)極(ji)(ji)與(yu)空(kong)載(zai)罐(guan)體間(jian)(jian)的(de)(de)(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)抗共同構成(cheng)平衡(heng)電(dian)(dian)(dian)(dian)(dian)橋電(dian)(dian)(dian)(dian)(dian)路并(bing)產(chan)生(sheng)一(yi)(yi)個(ge)穩定振蕩信(xin)號。當(dang)(dang)被測(ce)(ce)(ce)(ce)(ce)介質覆蓋探(tan)(tan)頭(tou)測(ce)(ce)(ce)(ce)(ce)量(liang)(liang)極(ji)(ji)時(shi)，會(hui)(hui)引起(qi)探(tan)(tan)頭(tou)測(ce)(ce)(ce)(ce)(ce)量(liang)(liang)極(ji)(ji)與(yu)罐(guan)體間(jian)(jian)的(de)(de)(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)抗變(bian)化(hua)(hua)導致(zhi)電(dian)(dian)(dian)(dian)(dian)橋電(dian)(dian)(dian)(dian)(dian)路不平衡(heng)而(er)(er)停止產(chan)生(sheng)振蕩信(xin)號，后(hou)級電(dian)(dian)(dian)(dian)(dian)路檢測(ce)(ce)(ce)(ce)(ce)到這一(yi)(yi)變(bian)化(hua)(hua)從而(er)(er)輸出報警信(xin)號。該振蕩信(xin)號作為(wei)(wei)射(she)頻(pin)信(xin)號施(shi)加在(zai)探(tan)(tan)頭(tou)測(ce)(ce)(ce)(ce)(ce)量(liang)(liang)極(ji)(ji)的(de)(de)(de)(de)(de)(de)同時(shi)，還經過(guo)1：1的(de)(de)(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)壓跟隨器后(hou)送往探(tan)(tan)頭(tou)的(de)(de)(de)(de)(de)(de)保護極(ji)(ji)，測(ce)(ce)(ce)(ce)(ce)量(liang)(liang)極(ji)(ji)與(yu)保護極(ji)(ji)的(de)(de)(de)(de)(de)(de)射(she)頻(pin)信(xin)號具有(you)(you)等電(dian)(dian)(dian)(dian)(dian)位(wei)、同相位(wei)、同頻(pin)率又互相隔離。當(dang)(dang)探(tan)(tan)頭(tou)有(you)(you)掛(gua)料(liao)時(shi)，測(ce)(ce)(ce)(ce)(ce)量(liang)(liang)極(ji)(ji)與(yu)保護極(ji)(ji)之(zhi)間(jian)(jian)因為(wei)(wei)沒有(you)(you)電(dian)(dian)(dian)(dian)(dian)勢差而(er)(er)形(xing)成(cheng)電(dian)(dian)(dian)(dian)(dian)氣隔離確保保護極(ji)(ji)的(de)(de)(de)(de)(de)(de)信(xin)號變(bian)化(hua)(hua)不影響檢測(ce)(ce)(ce)(ce)(ce)，使探(tan)(tan)頭(tou)測(ce)(ce)(ce)(ce)(ce)量(liang)(liang)極(ji)(ji)上電(dian)(dian)(dian)(dian)(dian)抗的(de)(de)(de)(de)(de)(de)變(bian)化(hua)(hua)只能由(you)探(tan)(tan)頭(tou)測(ce)(ce)(ce)(ce)(ce)量(liang)(liang)極(ji)(ji)與(yu)罐(guan)體間(jian)(jian)的(de)(de)(de)(de)(de)(de)物料(liao)決定，從而(er)(er)使探(tan)(tan)頭(tou)上的(de)(de)(de)(de)(de)(de)掛(gua)料(liao)不會(hui)(hui)影響正(zheng)常檢測(ce)(ce)(ce)(ce)(ce)。
