ROSEMOUNT傳感器499ATRDO系列介紹
ROSEMOUNT499ATrDO 傳感器是一種覆膜電流傳感器，用于連續(xù)測定水中 ppb 級溶解氧。主要應用是蒸汽冷凝水和鍋爐給水。
易于維護
· 通過簡單的膜和電解質(zhì)更換延長傳感器壽命； 無需特殊工具。
· 帶有集成Pt-100 電阻溫度裝置(RTD) 的自動溫度校正。
· 輕松的空中校準。
· 快速下降時間； 開箱即用的羅斯蒙特 499ATrDO 傳感器在投入使用后的 5 小時內(nèi)精確到 1 ppb 水平。
· Variopol (VP6) 電纜連接器選項消除了電纜扭曲并允許快速更換傳感器。
高性能設計
· 測量0.1 ppb 到20 ppm 之間的溶解氧。
· 在高達 122 °F (50 °C) 的過程溫度下運行。
· 測量濃度低于 20 ppb 時，精度高達 ±1.0 ppb。
· 內(nèi)部柔性氣囊可實現(xiàn)自動壓力平衡，從而將壓力變化對傳感器響應的影響降至最低。
The Rosemount 499ATrDO sensor is a membrane-covered amperometric sensor for the continuous determination of ppb-level dissolved oxygen in water. The primary application is steam condensate and boiler feedwater.
Ease of maintenance
· Extend sensor life with simple membrane and electrolyte replacement; no special tools needed.
· Automatic temperature correction with integral Pt-100 resistance temperature device (RTD).
· Easy in-air calibration.
· Fast comedown time; an out-of-the-box Rosemount 499ATrDO sensor is accurate at the 1 ppb level within five hours after being placed in service.
· Variopol (VP6) cable connector option eliminates cable twisting and allows for quick sensor replacement.
High performance design
· Measures dissolved oxygen between 0.1 ppb and 20 ppm.
· Operates in process temperatures up to 122 °F (50 °C).
· High accuracy of ±1.0 ppb when measuring concentrations below 20 ppb.
· Internal flexible bladder allows automatic pressure equalization for minimal influence from pressure changes on sensor response.
