style="text-indent:25px">無線雷達料位計價格雷達料位計是基于時間行程原理的測量儀表，雷達波以光速運行，運行時間可以通過電子部件被轉(zhuǎn)換成物位信號。探頭發(fā)出高頻脈沖并沿纜繩傳播，當(dāng)脈沖遇到物料表面時反射回來被儀表內(nèi)的接-收-器接收，并將距離信號轉(zhuǎn)化為物位信號。雷達波是一種特殊形式的電磁波，雷達料位計利用了電磁波的特殊性能來進行料位檢測。電磁波的物理特性與可見光相似，傳播速度相當(dāng)于光速。其頻率為300MHz-3000GHz。電磁波可以穿透空間蒸汽、粉塵等干擾源，遇到障礙物易于被反射，被測介質(zhì)導(dǎo)電性越好或介電常數(shù)越大，回波信號的反射效果越好。遼寧無線雷達料位計價格電容式料位計適用于高溫高壓容器的物位測量，且測量值不受被測液體的溫度。</p><div

重錘式料位計機電重錘式料位計是連續(xù)測量料位計。由探測單元和控制器組成。常用于粉狀物料和粒狀物料的連續(xù)測量。探測單元安裝在料庫頂上，用鋼絲繩(鋼帶)的末端系一重錘。當(dāng)需要測量時，電動機帶動重錘下降，至料面時，鋼繩(帶)的張力松馳，電動機停轉(zhuǎn)并反轉(zhuǎn)，使重錘回到庫頂。檢測鋼繩(帶)位移的距離，得出庫內(nèi)料位?？刂品矫妫瑱z測重錘接觸物料從而控制電動機啟停有不同的方式。控制器通常遠離環(huán)境惡劣的現(xiàn)場，設(shè)置在控制室，可與上位機聯(lián)網(wǎng)。重錘料位計安裝、運行注意事項:1)測量點的選擇:如料庫為中心進料，探頭單元應(yīng)安裝在料庫半徑的1/2處，探頭與進料口的水平距離要>1m，應(yīng)遠離下料口。2)由于測量重錘上升時有擺動，故在重錘升降時以。3)庫內(nèi)裝料時，不進行測量，因為進料可能埋錘，易造成故障。4)定時檢查清理探頭單元、鋼繩(帶)、測量錘等并定時校驗控制器。重錘式料位計是接觸式測量，基本上不受庫內(nèi)溫度、濕度、粉塵的影響，計量精度較高而且國產(chǎn)設(shè)備的價格相對較低，有的產(chǎn)品還具有在線和離線調(diào)試的功能。但維修工作量較大，主要是因為錘頭和鋼繩(帶)易被粉料粘裹，受粉料沖刷，造成斷繩、掉錘頭事故。目前，重錘料位計在水泥廠仍占有一定市場。鎳鐵爐料倉料位計怎么樣</p><p
