Cảm biến đo nhiệt độ bề mặt Campbell Scientific CS220-L
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.
Benefits and Features
- Well-suited for solar energy applications
- Thermocouple tolerance meets ASTM E230-ANSI MC 96.1 (reference junction at 0°C)
- Easy to install
- Compatible with most Campbell Scientific data loggers
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 consists of a stainless-steel overbraided cable and a thermocouple extension cable. Adhesive on one end of the overbraided cable secures the sensor to the solar panel. The mini connectors of the thermocouple extension and overbraided cables attach to each other. The pigtails of the extension cable connect to the data logger.
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.
The CS220 can be ordered with a cable length of zero feet to get the stainless-steel overbraided cable, but not the thermocouple extension cable.
