的電氣性能
兩線運(yùn)行功率是直接從4到20 mA回路獲得，不需要單獨(dú)的輸入功率。這簡(jiǎn)化了現(xiàn)場(chǎng)布線和消除電力線路噪聲拾取的可能性。
隔離1500 V RMS（2100分）
這非常高的CMV評(píng)級(jí)從輸入到輸出的情況下或消除電氣接地回路的信號(hào)源和接收機(jī)之間的可能性。它還提供了對(duì)電氣危險(xiǎn)接收機(jī)高度的保護(hù)，如信號(hào)源和一個(gè)交流電源線之間的意外接觸。
量程比
調(diào)節(jié)比為零抑制除以跨度。異常高的10:1的量程比可能與tx1500系列表明，寬零偏移可以聯(lián)合窄信號(hào)跨在高增益的閉環(huán)控制。信號(hào)跨度也可以大批量操作控制，在很寬的范圍內(nèi)的信號(hào)水平可能在整個(gè)批處理周期中。
高過壓保護(hù)
120伏的電壓可以被施加在輸入或輸出引線1分鐘在所有型號(hào)的熱電偶輸入電壓或情況。反400分的極性，可以應(yīng)用于輸出引線下去。這些異常高電壓等級(jí)NMV進(jìn)一步防止可能的電氣故障和接線錯(cuò)誤。
