兩線制電流變送器（上） </p> <p> 兩線制是指現(xiàn)場(chǎng)變送器與控制室儀表聯(lián)系*用兩根導(dǎo)線，這兩根線既是電源線，又是信號(hào)線。兩線制與三線制 (一根正電源線，兩根信號(hào)線,其中一根共GND) 和四線制(兩根正負(fù)電源線，兩根信號(hào)線,其中一根GND)相比，兩線制的優(yōu)點(diǎn)是： </p> <p> 1、不易受寄生熱電偶和沿電線電阻壓降和溫漂的影響，昆明JD6000生產(chǎn)廠商，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； </p> <p> 2、在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)線環(huán)路內(nèi)的電壓，昆明JD6000生產(chǎn)廠商，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。
