壓力變送器采用電流輸出的方式有很多優(yōu)勢(shì)：diyi、壓力變送器不易受寄生熱電偶和沿電線(xiàn)電阻壓降和溫漂的影響，常規(guī)導(dǎo)線(xiàn)就能滿(mǎn)足工況需求；可節(jié)省大量電纜線(xiàn)和安裝費(fèi)用。第二、當(dāng)壓力變送器電流源輸出電阻足夠大時(shí)，經(jīng)磁場(chǎng)耦合感應(yīng)到導(dǎo)線(xiàn)環(huán)路內(nèi)的電壓，不會(huì)產(chǎn)生明顯影響，因?yàn)楦蓴_源引起的電流極小，一般利用雙絞線(xiàn)就能降低干擾；三線(xiàn)制與四線(xiàn)制必須用屏蔽線(xiàn)，屏蔽線(xiàn)的屏蔽層要妥善接地。第三、電容性干擾會(huì)導(dǎo)致jieshouqi電阻產(chǎn)生有關(guān)誤差，對(duì)于4~ 20mA 兩線(xiàn)制環(huán)路， jieshouqi電阻通常為2508 （取樣Uou t=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(xiàn)長(zhǎng)度比電壓遙測(cè)系統(tǒng)更長(zhǎng)更遠(yuǎn)。第四、壓力變送器各個(gè)單臺(tái)示讀裝置或記錄裝置可以在電線(xiàn)長(zhǎng)度不等的不同通道間進(jìn)行換接，不因電線(xiàn)長(zhǎng)度的不等而造成精度的差異，從而實(shí)現(xiàn)分散采集、集中控制。第五、將4mA 用于零電平，使判斷開(kāi)路與短路或壓力變送器損壞（ 0mA 狀態(tài)）十分方便。第六、壓力變送器的兩線(xiàn)輸出口非常容易增設(shè)一兩只防雷防浪涌器件，有利于安全防雷防爆。 </p> <p> <br />

通用型壓力變送器采用壓阻式壓力傳感器。壓阻式傳感器是壓力式傳感器的一種。壓阻式壓力傳感器又稱(chēng)擴(kuò)散硅壓力傳感器。壓阻式壓力變送器,傳感器信號(hào)經(jīng)過(guò)信號(hào)處理電路后轉(zhuǎn)換為標(biāo)準(zhǔn)信號(hào)輸出，產(chǎn)品經(jīng)過(guò)了長(zhǎng)期老化及穩(wěn)定性考核等工藝嚴(yán)格篩選，性能穩(wěn)定可靠。應(yīng)用于環(huán)境比較惡劣的露天現(xiàn)場(chǎng)，同時(shí)要求能夠現(xiàn)場(chǎng)觀(guān)測(cè)壓力顯示、需要零點(diǎn)遷移和量程調(diào)節(jié)的場(chǎng)合。應(yīng)用領(lǐng)域：適用于石油、化工、冶金、電力、輕工、紡織、建材、水文地質(zhì)、食品、醫(yī)藥、環(huán)境控制等行業(yè)的過(guò)程控制和壓力測(cè)量。
