日本橫河YOKOGAWA ZR202S一體式防爆型氧化鋯氧分析儀
ZR202S是一體型分析儀，集探頭和轉換器于一身。兩種氧化鋯氧分析儀都無需采樣設備，并可直接將探頭安裝在煙道壁或爐體中，以測量煙氣中的氧氣濃度。轉換器顯示鋯池溫度和鋯池電動勢，以及氧氣濃度。該分析儀最適用于監(jiān)視燃燒，并控制性環(huán)境下各種工業(yè)爐中的低氧燃燒，如煉油廠、石化廠和天然氣廠。
特性：
l 嵌入式探頭加熱設備可現(xiàn)場更換，降低了維護成本。
l 探頭采用使用壽命長、可靠性高的氧化鋯傳感器。
l 分體型轉換器ZR
l 一體型ZR202S集探頭和轉換器于一身，以減少配線、管道和安裝成本。ZR202S單元采用光學開關，易于現(xiàn)場操作。
l 使用數(shù)字通信(HART)進行遠程維護，降低維護成本。
說明: HART是HART通信基金會的注冊商標。
