<p>工業(yè)酸堿濃度計(jì)都有哪些技術(shù)特點(diǎn)呢？</p><p>酸堿濃度計(jì)是帶微處理器的水質(zhì)在線監(jiān)測(cè)儀。該儀表廣泛用于火電、化工、鋼鐵酸洗等行業(yè)，如電廠對(duì)離子交換樹脂的再生，化工化學(xué)工業(yè)過程等，對(duì)水溶液中的化學(xué)酸或堿濃度進(jìn)行連續(xù)檢測(cè)和控制。</p><p>酸堿濃度計(jì)工作原理：</p><p>測(cè)量原理：儀表采用電導(dǎo)電ji式傳感器進(jìn)行測(cè)量（濃度電電i材料采用鉑金），為避免電j電ji化，儀表產(chǎn)生高穩(wěn)定度的正弦波信號(hào)加在電ji上，流過電ji的電流與被測(cè)溶液的濃度成正比，由前置放大器測(cè)量流過電ji的電流并轉(zhuǎn)換為電壓信號(hào)，經(jīng)程控放大、相敏檢波和濾波后得到反映濃度值的電壓信號(hào)；微處理器通過開關(guān)切換，對(duì)溫度信號(hào)和濃度信號(hào)交替采樣，經(jīng)過運(yùn)算和溫度補(bǔ)償運(yùn)算后，轉(zhuǎn)換并顯示為25℃時(shí)被測(cè)量的濃度值和即時(shí)的溫度值。</p><p>自動(dòng)溫度補(bǔ)償原理：被測(cè)溶液的濃度與其電導(dǎo)率呈非線性正比，而溶液的電導(dǎo)率受溫度影響而變化，需要進(jìn)行溫度補(bǔ)償，各種溶液的溫度特性均不一樣，由微處理器來進(jìn)行相關(guān)的處理就變得既快又準(zhǔn)確，實(shí)現(xiàn)了自動(dòng)溫度補(bǔ)償?shù)墓δ堋?/p><p>特點(diǎn)：

</p><p>2.采用變頻勵(lì)磁電源和諧振電路及其*的信號(hào)采樣方式，取代單一頻率勵(lì)磁方式，使檢測(cè)變壓器的3.輸出電壓提高幾百倍。流通式傳感器采用了低溫磁結(jié)構(gòu)和鐵磁屏蔽，無零點(diǎn)漂移現(xiàn)象，大地改善了儀表的精度、靈敏度以及穩(wěn)定性 </p><p>4.使用微控制器（MCU)和接口集成電路，對(duì)檢測(cè)變壓器的輸出電壓和溫度傳感器輸出電流進(jìn)行全數(shù)字化采樣、計(jì)算、顯示、能夠?qū)崿F(xiàn)高精度的溫度補(bǔ)償以及濃度數(shù)值的就地顯示和遠(yuǎn)傳輸出.</p><p><br/></p> </div> <div id="popra85"
