數(shù)字變送器主要特點(diǎn)1、數(shù)字量輸出，采用光纖傳輸，可有效避免傳輸過(guò)程的損耗和電磁干擾；2、雙通道測(cè)量，可以是一路電壓、一路電流或兩路電壓或兩路電流的組合。每個(gè)通道的量程可配置。電壓、電流組合可以實(shí)現(xiàn)功率測(cè)量，兩個(gè)相同屬性通道可用于實(shí)現(xiàn)微差測(cè)量；3、同一個(gè)測(cè)量通道即可測(cè)量模擬量，又可測(cè)量脈沖量。

mA，通過(guò)250 Ω的精密電阻轉(zhuǎn)換成1～5 V或2-10V的模擬電壓信號(hào).轉(zhuǎn)換成數(shù)字信號(hào)有多種方法，系統(tǒng)的輸入模塊采用壓頻轉(zhuǎn)換器件LM231將模擬電壓信號(hào)轉(zhuǎn)換成頻率信號(hào)，用光電耦合器件TL117進(jìn)行模擬量與數(shù)字量的隔離。同時(shí)模擬信號(hào)處理電路與數(shù)字信號(hào)處理電路分別使用兩組**的電源，模擬地與數(shù)字地相互分開(kāi)，這樣可提高系統(tǒng)工作的安全性。利用壓頻轉(zhuǎn)換器件LM231也有一定的抗高頻干擾的作用。JD6000、單功能變送器功能，昆明英派爾科技有限公司。</p><div

3、電容性干擾會(huì)導(dǎo)致接收器電阻有關(guān)誤差，對(duì)于4～20mA兩線制環(huán)路，接收器電阻通常為250Ω（取樣Uout=1～5V）這個(gè)電阻小到不足以產(chǎn)生明顯誤差，因此，可以允許的電線長(zhǎng)度比電壓遙測(cè)系統(tǒng)更長(zhǎng)更遠(yuǎn)； </p> <p> 4、各個(gè)單臺(tái)示讀裝置或記錄裝置可以在電線長(zhǎng)度不等的不同通道間進(jìn)行換接，不因電線長(zhǎng)度的不等而造成精度的差異，實(shí)現(xiàn)分散采集，分散式采集的好處就是：分散采集，集中控制.... </p> <p> 5、將4mA用于零電平，使判斷開(kāi)路與短路或傳感器損壞（0mA狀態(tài)）十分方便。 </p> <p>
