style="text-indent:25px">壓力變送器的主要作用把壓力信號(hào)傳到電子設(shè)備，進(jìn)而在計(jì)算機(jī)顯示壓力其原理大致是：將水壓這種壓力的力學(xué)信號(hào)轉(zhuǎn)變成電流（4-20mA）這樣的電子信號(hào)壓力和電壓或電流大小成線性關(guān)系，一般是正比關(guān)系。所以，變送器輸出的電壓或電流隨壓力增大而增大由此得出一個(gè)壓力和電壓或電流的關(guān)系式壓力變送器的被測介質(zhì)的兩種壓力通入高、低兩壓力室，低壓室壓力采用大氣壓或真空，作用在δ元（即敏感元件）的兩側(cè)隔離膜片上，通過隔離片和元件內(nèi)的填充液傳送到測量膜片兩側(cè)。壓力變送器是由測量膜片與兩側(cè)絕緣片上的電極各組成一個(gè)電容器。當(dāng)兩側(cè)壓力不一致時(shí)，致使測量膜片產(chǎn)生位移，其位移量和壓力差成正比，故兩側(cè)電容量就不等，通過振蕩和解調(diào)環(huán)節(jié)，轉(zhuǎn)換成與壓力成正比的信號(hào)。</p><p style="text-indent:25px">電導(dǎo)變送器由于電解質(zhì)溶液與金屬導(dǎo)體一樣的電的良導(dǎo)體，因此電流流過電解質(zhì)溶液時(shí)必有電阻作用，且符合歐姆定律。但液體的電阻溫度特性與金屬導(dǎo)體相反，具有負(fù)向溫度特性。為區(qū)別于金屬導(dǎo)體，電解質(zhì)溶液的導(dǎo)電能力用電導(dǎo)（電阻的倒數(shù)）或電導(dǎo)率（電阻率的倒數(shù)）來表示。當(dāng)兩個(gè)互相絕緣的電極組成電導(dǎo)池時(shí)，若在其中間放置待測溶液，并通以恒壓交變電流，就形成了電流回路。如果將電壓大小和電極尺寸固定，則回路電流與電導(dǎo)率就存在一定的函數(shù)關(guān)系。這樣，測了待測溶液中流過的電流，就能測出待測溶液的電導(dǎo)率。傳感器及變送器在使用中應(yīng)按行業(yè)規(guī)定進(jìn)行周期檢定。</p><div

style="text-indent:25px">顧名思義，差壓變送器所測量的結(jié)果是壓強(qiáng)差，即△P=ρg△h。而由于油罐往往是圓柱形，其截面圓的面積S是不變的，那么，重力G=△P·S=ρg△h·S，S不變，G與△P成正比關(guān)系。即只要準(zhǔn)確地檢測出△P值，與液位高度h成反比，與高度差△h成正比，在溫度變化時(shí)，雖然油品體積膨脹或縮小，實(shí)際液位升高或降低，所檢測到的壓力始終是保持不變的。如果用戶需要顯示實(shí)際液位，也可以引入介質(zhì)溫度補(bǔ)償予以解決。正負(fù)遷移：零點(diǎn)經(jīng)過正遷移或負(fù)遷移后，量程、測量范圍的上限值和下限值的相對(duì)值，均不能超過測量范圍上限的100%。(智能型：量程比15：1)比較大的正遷移量為較小調(diào)校量程的500%；比較大的負(fù)遷移量為較小調(diào)校量程的600%。電導(dǎo)變送器它是通過測量溶液的電導(dǎo)值來間接測量離子濃度的流程儀表。合肥變送器價(jià)錢</p><p

style="text-indent:25px">變送器的種類很多，按工作能源分，有氣動(dòng)變送器、電動(dòng)變送器；按被測參數(shù)分，有差壓、壓力、流量、溫度、液位等變送器。變送器在儀器、儀表和工業(yè)自動(dòng)化領(lǐng)域中起著舉足輕重的作用。與傳感器不同，變送器除了能將非電量轉(zhuǎn)換成可測量的電量外，一般還具有一定的放大作用。壓力變送器也稱差變送器，主要由測壓元件傳感器、模塊電路、顯示表頭、表殼和過程連接件等組成。它能將接收的氣體、液體等壓力信號(hào)轉(zhuǎn)變成標(biāo)準(zhǔn)的電流電壓信號(hào)，以供給指示報(bào)警儀、記錄儀、調(diào)節(jié)器等二次儀表進(jìn)行測量、指示和過程調(diào)節(jié)。合肥變送器價(jià)錢</p></p><br
