1.1溫度變送器工作原理：一體化溫度變送器一般由測溫探頭（熱電偶或熱電阻傳感器）和兩線制固體電子單元組成。采用固體模塊形式將測溫探頭直接安裝在接線盒內(nèi)，從而形成一體化的變送器。一體化溫度變送器一般分為熱電阻和熱電偶型兩種類型。 </p> <p> 熱電阻溫度變送器是由基準(zhǔn)單元、R/V轉(zhuǎn)換單元、線性電路、反接保護、限流保護、V/I轉(zhuǎn)換單元等組成。測溫?zé)犭娮栊盘栟D(zhuǎn)換放大后，再由線性電路對溫度與電阻的非線性關(guān)系進行補償，經(jīng)V/I轉(zhuǎn)換電路后輸出一個與被測溫度成線性關(guān)系的4～20mA的恒流信號。浙江轉(zhuǎn)速變送器誠信經(jīng)營可對旋轉(zhuǎn)機械的轉(zhuǎn)速進行實時監(jiān)測。主要用于汽輪機、水泵、風(fēng)機等旋轉(zhuǎn)機械的轉(zhuǎn)速測量。</p><div

通用型接近傳感器的工作原理：振蕩電路中的線圈L產(chǎn)生一個高頻磁場。當(dāng)目標(biāo)物接近磁場時，由于電磁感應(yīng)在目標(biāo)物中產(chǎn)生一個感應(yīng)電流(渦電流)。隨著目標(biāo)物接近傳感器，感應(yīng)電流增強，引起振蕩電路中的負(fù)載加大。然后，振蕩減弱直至停止。傳感器利用振幅檢測電路檢測到振蕩狀態(tài)的變化，并輸出檢測信號。 <p> 接近傳感器的選型： </p> <p> 對于不同的材質(zhì)的檢測體和不同的檢測距離，應(yīng)選用不同類型的接近傳感器，以使其在系統(tǒng)中具有高的性能價格比 </p> </p> <p> <br /> </p> <p> <br /> </p>按照頻閃原理，當(dāng)高速閃光的頻率和目標(biāo)的rpm轉(zhuǎn)速（移動）同步時，在觀察者的眼中，目標(biāo)是靜靜止的。同其它的測量方法如機械法或光學(xué)傳感器法直比，頻閃原理的優(yōu)點顯而易見：這種方法可以用于測量小型目標(biāo)或不便觸及部位的rpm，而不需要在待測目標(biāo)上固定反射條。例如，如用于生產(chǎn)過程測量時，便不需中止。測量范圍：100至20000rpm。除了測量rpm轉(zhuǎn)速外，頻閃測量法還可用于振動分析和動作監(jiān)控。 <p> 目前，在以光電編碼器構(gòu)成的測速系統(tǒng)中，常用的數(shù)字式轉(zhuǎn)速測量方法主要有三種，分別是M法（頻率法）、T法（周期法）、M/T法（頻率／周期法）。M法是在既定的檢測時間內(nèi)，測量所產(chǎn)生的轉(zhuǎn)速脈沖信號的個數(shù)來確定轉(zhuǎn)速，比較適 </p> <p> <br />
