Ideal for monitoring solar panel temperatures
概述
The CS220 thermocouple measures the temperature of a surface by direct contact. It typically monitors the temperature of a solar panel, but can also monitor the temperature of other devices. Panel temperature is an important measurement in solar energy applications because the solar panel output is affected by its temperature. As the solar panel temperature increases, the output decreases.

Detailed Description
The CS220 uses a 24-AWG, twisted pair, shielded, fast response type E thermocouple. Type E thermocouples consist of a chromel wire and a constantan wire joined at a measurement junction. A voltage potential is generated when the measurement end of the thermocouple is at a different temperature than the reference end of the thermocouple. The magnitude of the voltage potential is related to the temperature difference. Therefore, temperature can be determined by measuring the differences in potential created at the junction of the two wires.
A reference temperature measurement is required for thermocouple measurements. The temperature sensor built into many of our data loggers' wiring panel typically provides this measurement.

The CS220 can provide the temperature on the back of a solar panel, which is an important measurement in solar energy applications. The output of a solar panel is affected by its temperature. As the temperature of the solar panel increases, its output decreases.
Replacement SensorThe CS220 can be ordered with a cable length of zero feet to get the stainless-steel overbraided cable, but not the thermocouple extension cable. |

其他兼容性信息
Installation
The CS220 usually adheres in the center of the back panel of a solar module. Once the mounting location is determined, clean the back panel surface. Use extreme caution removing the masking paper from the measurement end of the thermocouple; damage can occur if masking paper is not removed carefully. Once masking paper is removed, firmly press thermocouple to the panel. Adhere the cable strain relief 2 to 3 in. from the end. Connect the mini connector on the stainless-steel overbraided cable to the mini connector on the thermocouple extension cable. Wire the pigtails of the thermocouple extension cable to the data logger, as determined by the data logger program/wiring table.
Multiplexers
If large numbers of CS220s need to be measured, the AM25T Thermocouple Multiplexer is recommended.
Data Logger Considerations
每个探针需要一个差分通道；还需要数据记录器处的热电偶参考连接。
Programming
The CS220 is measured by the TCDiff instruction in CRBasic and by Instruction 14 (Differential Thermocouple) in Edlog. The CR200(X)-series, CR500, and CR510 dataloggers do not have thermocouple measurement instructions and are therefore not compatible with the CS220.
参考温度测量
需要参考温度测量。测量参考温度的选项包括：
- CR800，CR850，CR1000，CR3000或CR5000接线面板内置的热敏电阻
- prt内置在CR9050或
- CR9051E CR9000X测量和控制Datalogger的输入模块
- CR7 23T输入卡的接线面板中内置的PRT，用于CR7测量和控制Datalogger
- 连接到CR10X接线面板的CR10XTCR热敏电阻

Campbell Scientific建议大约100欧姆循环阻力。这意味着，使用E型热电偶，基于24个AWG线，最大值约为100英尺。可能会超出该距离，但不建议使用。OMEGA provides a “Resistance vs. Wire Diameter” table that displays the resistance per double foot. See第H-8页this PDF. Using this table, it is easy to determine how many feet can be run with any particular gauge.
-
The response time is 0.15 s. The CS220-L can be used as a self-adhering thermocouple for temperatures from -40° to +260°C.
-
Magnetic fields do affect thermocouples, but Campbell Scientific data loggers are designed for thermocouple measurements and have built-in tools to make the best measurements possible.
Some suggestions for better measurements:
- 使用与屏蔽层绑在数据记录端的盾牌的热电偶。
- Use theTCDiff()和tcse（）指示。在这些说明中，可以使用50和60 Hz的噪声过滤器。
- 切勿在与交流电压相同的导管中运行热电偶电线。
