ROSEMOUNT传感器499ATRDO系列介绍
ROSEMOUNT499ATrDO 传感器是一种覆膜电流传感器，用于连续测定水中 ppb 级溶解氧。主要应用是蒸汽冷凝水和锅炉给水。
易于维护
· 通过简单的膜和电解质更换延长传感器寿命； 无需特殊工具。
· 带有集成Pt-100 电阻温度装置(RTD) 的自动温度校正。
· 轻松的空中校准。
· 快速下降时间； 开箱即用的罗斯蒙特 499ATrDO 传感器在投入使用后的 5 小时内精确到 1 ppb 水平。
· Variopol (VP6) 电缆连接器选项消除了电缆扭曲并允许快速更换传感器。
高性能设计
· 测量0.1 ppb 到20 ppm 之间的溶解氧。
· 在高达 122 °F (50 °C) 的过程温度下运行。
· 测量浓度低于 20 ppb 时，精度高达 ±1.0 ppb。
· 内部柔性气囊可实现自动压力平衡，从而将压力变化对传感器响应的影响降至最低。
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.
