兼容所有的Campbell Scientific数据采集器
概览
CS511为可浸入的、坚实耐用的、低维护的传感器，用于检测介质（通常为水体）中的溶解氧的多少。传感器生成的信号与当前氧气数量成比例，信号可以被我们的数据采集器所测量。
优势与特点
- In-line thermistor provides automatic temperature compensation
- Compatible with most Campbell Scientific dataloggers

技术说明
CS511含有一个自极化自发电池，生成与被测量介质（通常为水体）中含氧量成比例的毫伏信号。氧气通过渗透膜扩散到阴极，发生化学反应，生成电流，通过串联电阻将微安转换成毫伏信号；一个在线热敏电阻提供自动温度补偿。

当前，CS511为Sensorex’的DO6400/T型号；在2008年6月之前，CS511为Sensorex’的DO6200/T型号。这两种型号传感器的编程、接线和大多数技术规范都一样。不过，它们使用不同的附件，所以看起来有些不一样。老版本的DO6200/T的备件仍然可以订购（见订货信息）。 CS511使用说明书（右侧）含有DO6400/T 和 DO6200/T两者的图片，可以帮助您识别传感器。寻求更多信息请联系Campbell Scientific。 |

Additional Compatibility Information
DO Electrolyte
Because the CS511 is shipped dry, DO electrolyte needs to be added before using the sensor. DO electrolyte as well as spare membranes are included in the sensor’s shipping kit.

-
No. The cable is attached to the internal electronics. Removing them would be a violation of the warranty.
-
Yes. This probe is completely submersible.
-
If the probe will be shelved for a month or more, the electrode should be removed. When the sensor will be used again, use fresh electrolyte and a new membrane. Following these guidelines will enable the probe to be stored indefinitely.

The CS511-L is a galvanic dissolved-oxygen probe that is designed to work in water. As O2 passes through the semipermeable membrane, the oxygen reacts with the electrolyte solution in the probe. As more oxygen becomes available, an electro-chemical process occurs, so that an increase in the mV output is recorded. The source of the oxygen can be through the air, water, or a liquid slurry. Soil is not very homogeneous, so the dissolved oxygen is not able to move freely.
