56 型*的雙輸入分析儀

 56 型分析儀是線路供電分析儀，提供單傳感器或雙傳感器輸入，且雙測(cè)量可任意組合。 56 型分析儀可測(cè)量 pH 值、ORP、ISE、電導(dǎo)率、氯、溶解氧和氣態(tài)氧、溶解臭氧、溫度、濁度或流量，并將接受 4-20mA 電流輸入。設(shè)備的供電電源為 24VDC 或 115/230AC（ 自動(dòng)切換）。HART 數(shù)字通訊是標(biāo)準(zhǔn)功能。

該儀器支持 Rosemount Analytical 的智能 pH 傳感器。所有組態(tài)均滿足通用場(chǎng)所的 UL 認(rèn)證要求。

特殊功能

• 全彩顯示器： 高分辨率的全彩顯示器（480 x 272 像素）
• 就地操作員接口： 屏幕與計(jì)算機(jī)相似，便于查找本機(jī)組態(tài)和日常標(biāo)定。 
• 診斷：連續(xù)監(jiān)測(cè)分析儀和傳感器回路，了解故障和警告狀態(tài)。
• 數(shù)據(jù)記錄器： 連續(xù) 30 天每 30 秒記錄一次兩個(gè)通道的數(shù)據(jù)以及溫度
• 事件記錄器審計(jì)跟蹤：zui多可記錄 300 個(gè)重要事件
• PID 控制：比例、積分和微分設(shè)置，zui多可提供 4 個(gè)模擬電流輸出，用于連續(xù)調(diào)整控制設(shè)備
• 實(shí)時(shí)時(shí)鐘： 將時(shí)間/日期標(biāo)簽施加到所有過(guò)程數(shù)據(jù)和事件上
• USB 數(shù)據(jù)端口：傳輸本機(jī)的全部過(guò)程數(shù)據(jù)和事件，以便在計(jì)算機(jī)上對(duì)其進(jìn)行評(píng)估
• 計(jì)時(shí)器功能：時(shí)間比例控制，具有間隔計(jì)時(shí)器和 4 個(gè)特殊應(yīng)用計(jì)時(shí)器：排放和注入、天數(shù)和時(shí)間間隔計(jì)時(shí)器、延遲計(jì)時(shí)器和流量積算器。 
• 安全訪問(wèn)：雙重密碼訪問(wèn)
• 診斷： 連續(xù)監(jiān)測(cè)和記錄分析儀和傳感器的故障狀態(tài)
• 準(zhǔn)無(wú)線裝備： HART 信號(hào)可通過(guò)無(wú)線 THUM 適配器，在人員難以到達(dá)的位置，進(jìn)行過(guò)程變量和診斷信息的無(wú)線傳輸。
