                                                          秒準（Mayzum）MAY-2001/MAY-2001H-JQ
                                                                         在線甲醛溶液濃度在線監(jiān)控儀

一、工作原理：MAY-2001-JQ在工作時，通過內置的電機產生的高頻振動在不同密度濃度的液體介質中產生的振動頻率不同，振動的頻率通過一個壓電晶體檢測出來，通過移相和放大電路，再由微處理器轉換成密度濃度數(shù)字信號；通常情況下不同濃度的液體，其密度與濃度會呈現(xiàn)一定的數(shù)學關系。
二、適用國標：符合工業(yè)用甲醛溶液甲醇溶液濃度測試標準。
三、特點描述：
1、即插即用，免維護：安裝方式靈活（安裝于管道、槽體、反應釜、儲罐…）、體積小巧，安裝方式多樣化，可選卡箍/法蘭/螺紋安裝；
 
2、擁有強大的數(shù)據(jù)庫，內置0-80℃溫度補償數(shù)據(jù)，克服了單片機內存小，溫度補償范圍受限制的缺點。溫度傳感器與密度探頭集成，緊貼測量介質，保證溫度補償及時、準確、可靠；
 
3、不受介質顏色變化影響，不易受振動、壓力變化的影響；
 
4、出廠附帶標定證書，無需現(xiàn)場校準，也不需要定期校準；
5、用戶自定義上下限報警，觸屏輸入，操作簡單易懂，現(xiàn)場可接報警燈；
 
6、標配多組信號模擬輸出：可選4-20mA、RS485/232數(shù)字量、開關量（異常報警,上下限2路輸出），便于客戶集成控制，提高自動化程度，提高生產效率；
 
7、采用4.3寸觸屏人機交互界面，顯示內容更詳細，彩色界面，操作便利，可拓展性強，可按用戶需求定制界面和功能；
 
8、數(shù)據(jù)自動保存，便于查詢：歷史數(shù)據(jù)查詢、生成歷史數(shù)據(jù)曲線，快捷查詢、導出EXCEL，自動數(shù)據(jù)分析與匯總，數(shù)據(jù)保存周期12個月，便于溯源（需選配MAY-LST歷史數(shù)據(jù)存儲功能）；
 
9、支持sqlite數(shù)據(jù)庫，可存儲高達16G的歷史數(shù)據(jù)，數(shù)據(jù)可通過U盤導出到電腦或者通過無線遠傳功能實時遠傳至PLC、PC、DCS等上位機系統(tǒng)；通過PC遠程查看實時狀態(tài)與報警。（需選配MAY-LOT數(shù)據(jù)遠傳模塊）
 
10、連續(xù)測量，迅速反饋，消除人工檢測誤差，不再需要人工頻繁取樣檢測，節(jié)省大量人力財力，保證數(shù)據(jù)一致性，提升產品質量；
 
11、采用智能化芯片，運行無需試劑耗材，功耗低，穩(wěn)定性高，使用壽命長。
四、規(guī)格參數(shù)選型表：
五、顯示界面參考圖：
