雷達(dá)液位計(jì)主要由電子元件和天線構(gòu)成，無可動部件，在使用中的故障極少使用中偶爾遇到的問題是，貯槽中有些易揮發(fā)的有機(jī)物會在雷達(dá)液位計(jì)的喇叭口或天線上結(jié)晶，對它們只要定期檢査和清理即可，維護(hù)量少。 </p> <p> 在日常維護(hù)中，可以用PC機(jī)遠(yuǎn)程觀察反射波曲線圖，對于后來可能新產(chǎn)生的干擾波，可以利用液位計(jì)有識別虛假波的功能，除去這些干擾反射波的影響，保證準(zhǔn)確測量 </p> <p> <br /> </p> <p> 雷達(dá)液位計(jì)屬于通用型雷達(dá)液位計(jì)， </p> <p> 它基于時(shí)間行程原理的測量儀表，雷達(dá)波以光速運(yùn)行，運(yùn)行時(shí)間可以通過電子部件被轉(zhuǎn)換成物位信號。探頭發(fā)出高頻脈沖在空間以光速傳播，當(dāng)脈沖遇到物料表面時(shí) </p> <p> 反射回來被儀表內(nèi)的***接收，并將距離信號轉(zhuǎn)化為物位信號。 </p> <p> <br /> </p><p> 測量原理 </p> <p> 雷達(dá)液位計(jì)是依據(jù)時(shí)域反射原理(TDR)為基礎(chǔ)的雷達(dá)液位計(jì)，雷達(dá)液位計(jì)的電磁脈沖以光速沿鋼纜或探棒傳播，當(dāng)遇到被測介質(zhì)表面時(shí)，雷達(dá)液位計(jì)的部分脈沖被反射形成回波并沿相同路徑返回到脈沖發(fā)射裝置，發(fā)射裝置與被測介質(zhì)表面的距離同脈沖在其間的傳播時(shí)間成正比，經(jīng)計(jì)算得出液位高度 </p> <p> <br /> </p> <p> 注意事項(xiàng) </p> <p> 1.測量范圍從波束觸及罐低的那一點(diǎn)開始計(jì)算，但在特殊情況下，若罐底為凹型或錐形，當(dāng)物位低于此點(diǎn)時(shí)無法進(jìn)行測量。 </p> <p> 2.若介質(zhì)為低介電常數(shù)當(dāng)其處于低液位時(shí)，罐底可見，此時(shí)為保證測量精度，建議將零點(diǎn)定在低高度為C 的位置。 </p> <p> 3.理論上測量達(dá)到天線前列的位置是可能的，但是考慮到腐蝕及粘附的影響，測量范圍的終值應(yīng)距離天線的前列至少100mm。 </p> <p> 4.對于過溢保護(hù)，可定義一段安全距離附加在盲區(qū)上。 </p> <p> 5.**小測量范圍與天線有關(guān) </p> <p> <br /> </p> <p> <br /> </p> <p> <br /> </p><div style="width:100%;text-align: center;"><img style="max-width: 640px;
