burkert8175型非接觸式液位變送器,BURKERT液位變送器
Burkert8175型為非接觸式液位變送器件的出現(xiàn)使這個(gè)問(wèn)題得到了較好地解決。我們以DH4-20變送模塊為核心設(shè)計(jì)了小型、價(jià)廉的穿孔型兩線制電流變送器。它具有低失調(diào)電壓（＜30 μV）、低電壓漂移（＜0.7μV/C°）、超低非線性度（＜0.01%）的特點(diǎn)。它把現(xiàn)場(chǎng)設(shè)備動(dòng)力線的電流隔離轉(zhuǎn)換成4～20 mA的按線性比例變化的標(biāo)準(zhǔn)電流信號(hào)輸出，然后通過(guò)對(duì)雙絞線送到監(jiān)測(cè)系統(tǒng)的輸入接口上，雙絞線同時(shí)也將位于監(jiān)測(cè)系統(tǒng)的24V工作電源送到電流變送器中。測(cè)量信號(hào)和電源在雙絞線上同時(shí)傳送，既省去了昂貴的傳輸電纜，而且信號(hào)是以電流的形式傳輸，抗干擾能力得到極大的加強(qiáng)。兩線制電流變送器原理如（圖1）所示。
