從2017年9月30日起，DP18系列將停產(chǎn)。作為升級(jí)替代品，請(qǐng)查看DP20系列了解詳細(xì)信息。

DP18系列采用模塊化設(shè)計(jì)，便于選擇和安裝選件和輸入?？砂惭b的信號(hào)調(diào)節(jié)器卡為大用戶或OEM提供了庫(kù)存選件和備用信號(hào)的能力用于轉(zhuǎn)換輸入類型、儀表功能或維修的調(diào)節(jié)器卡。對(duì)于需要靈活隨著要求越來(lái)越苛刻，DP18的現(xiàn)場(chǎng)安裝模擬量增加了選件輸出、繼電器和通信提供了一種經(jīng)濟(jì)的解決方案。

DP18系列是完整的面板儀表系列，帶有電壓、過(guò)程和溫度輸入卡測(cè)量和控制。電壓信號(hào)調(diào)節(jié)器將測(cè)量交流或直流電壓或真RMS。信號(hào)用于過(guò)程輸入的調(diào)節(jié)器接受低電平電壓或電流，這些電壓或電流可以根據(jù)工程設(shè)計(jì)進(jìn)行擴(kuò)展單位。溫度計(jì)將提供熱電偶或RTD的精準(zhǔn)測(cè)量。其他輸入包括差分過(guò)程、稱重傳感器或電位計(jì)。結(jié)合OMEGA的廣泛選擇傳感器，DP18系列是過(guò)程測(cè)量的單一解決方案。
