Cole-Parmer 氯传感器，0到10 PPM，4至20 mA输出

Cole-Parmer® Free Chlorine Sensor, 0 to 10 ppm, 4 to 20 mA output

其他氯和二氧化氯传感器的经济型替代品
4至20 mA输出信号直接送入到大部分PLC，数据采集器，或图表记录仪
提供多范围
设计用于在水处理中的应用。传感器在线，实时测量，也可供两个量程pH值范围为4至11，用于检测ppm级的二氧化氯。传感器与臭氧有一些交叉灵敏度。三个层次的游离氯可以测量pH值5.5至8.0之间。传感器与臭氧反应，溴，二氧化氯有一定的交叉。
传感器具有内部ATC和信号调节器提供4至20 mA输出信号在测量范围。传感器和流通池，可用于新安装或替换其他4至20 mA输出传感器。安装在现有的环路供电系统或为了供电面板仪表94785-12 大多数应用中使用寿命超过一年。膜帽和填充液可更换传感器使其寿命最大化;单独订货。
An economical replacement for other chlorine and chlorine dioxide sensors
4 to 20 mA output signal feeds directly into most PLCs, dataloggers, or chart recorders
Multiple ranges available
Designed for use in water treatment applications. Sensors measure on-line, in real-time, and are available in two ranges for detecting ppm levels of chlorine dioxide within a pH range of 4 to 11. Sensors have some cross sensitivity with ozone. Three levels of free chlorine can be measured between pH 5.5 to 8.0. Sensors have some cross reactivity with ozone, bromine, and chlorine dioxide.
Sensors feature an internal ATC and signal conditioner to provide a 4 to 20 mA output signal over the measurement range. Sensors and flow cells can be used for new installations or as replacements for other 4 to 20 mA output sensors. Install in existing loop-powered systems or order powered panel meter 94785-12. 

Service life exceeds one year in most applications. Membrane caps and fill solution can be replaced to maximize sensor life; order separately.
