一.什么是兩線制的電流變送器?
什么是兩線制?兩線制有什么優(yōu)點(diǎn)?
兩線制是指現(xiàn)場變送器與控制室儀表僅僅可以用兩根導(dǎo)線,這兩根線既是電源線,又是信號線。兩線制和三線制 (一根正電源線,兩根信號線,其中一根共GND) 與四線制(兩根正負(fù)電源線,兩根信號線,其中一根GND)相比,兩線制的優(yōu)點(diǎn)是:
1、不易受寄生熱電偶以及沿電線電阻壓降和溫漂的影響,可用非常便宜的更細(xì)的導(dǎo)線;可節(jié)省大量電纜線和安裝費(fèi)用;
2、在電流源輸出電阻足夠大時(shí),經(jīng)過磁場耦合感應(yīng)到導(dǎo)線環(huán)路內(nèi)的電壓,不會產(chǎn)生顯著影響,因?yàn)楦蓴_源引起的電流極小,一般利用雙絞線就能降低干擾;兩線制與三線制必須用屏蔽線,屏蔽線的屏蔽層要妥善接地。
3、電容性干擾會導(dǎo)致接收器電阻有關(guān)誤差,對于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)生顯著誤差,所以,可以允許的電線長度比電壓遙測系統(tǒng)更長更遠(yuǎn);
