工業(yè)生產(chǎn)中，測(cè)量元件將壓力，溫度，流量，液位等參數(shù)檢測(cè)出來之后，需要由變送器將測(cè)量元件的信號(hào)統(tǒng)一轉(zhuǎn)換為標(biāo)準(zhǔn)的信號(hào)源（如4~20mA直流電源），送往顯示儀表或調(diào)節(jié)儀表進(jìn)行顯示，記錄或者調(diào)節(jié)。因此說，變送器既是一種轉(zhuǎn)換介質(zhì)，更是一種媒介。 </p> <p> 變送器強(qiáng)在哪 </p> <p> 由于調(diào)節(jié)器一般都在距離相對(duì)較遠(yuǎn)的控制室中，變送器就成了信號(hào)產(chǎn)生和傳輸線驅(qū)動(dòng)這兩個(gè)功能的復(fù)合體，成為了整個(gè)控制裝置中的心臟，有了它，才使得控制端和測(cè)量端聯(lián)系起來，構(gòu)成了整套控制系統(tǒng)。 </p><p> 轉(zhuǎn)速變送器 </p> <p> 采用霍爾效應(yīng)原理，當(dāng)金屬齒經(jīng)過霍爾傳感器前端時(shí)，引起磁場(chǎng)變化，霍爾元件檢測(cè)到磁場(chǎng)變化，并轉(zhuǎn)換成一個(gè)交變電信號(hào)，傳感器內(nèi)置電路對(duì)該信號(hào)進(jìn)行放大、整形，輸出良好的矩形脈沖信號(hào)，測(cè)量頻率范圍更寬，可以測(cè)量0轉(zhuǎn)速，輸出信號(hào)也更精確穩(wěn)定，并且安裝簡(jiǎn)單，廣泛應(yīng)用于車輛，電機(jī)，風(fēng)機(jī)，汽輪機(jī)的轉(zhuǎn)速測(cè)量。

1）通電情況下，嚴(yán)禁打開電子單元蓋和端子蓋，允許進(jìn)行外觀檢查：檢查變送器，配管配線的腐蝕、損壞程度以及其它機(jī)械結(jié)構(gòu)件的檢查。 </p> <p> 2）零點(diǎn)和滿度調(diào)整：禁止在現(xiàn)場(chǎng)打開端子蓋和視窗，只許在控制室內(nèi)用手持通訊器進(jìn)行調(diào)整。 </p> <p> 3）擱爆變送器的修理必須斷電后在安全場(chǎng)所進(jìn)行。或開關(guān)量信號(hào)等，送給PLC、DCS或DEH系統(tǒng)等。它的主要特點(diǎn)是體積小，安裝方便。上海轉(zhuǎn)速變送器誠(chéng)信經(jīng)營(yíng)</p><p
