RS485 4-20MA 0-5V 0-10V 0.3-3μm SPECTRAL RANGE SENSOR TOTAL SOLAR RADIATION SENSORS
Product introduce
The total radiation sensor can be used to measure the total solar radiation in the spectral range of 0.3 to 3 μm (300 to 3000 nm). If the sensing surface is turned down to measure reflected radiation, the shading ring can also measure scattered radiation. The core device of the radiation sensor is a high-precision photosensitive element, which has good stability and high accuracy. At the same time, a precision-processed PTTE radiation cover is installed outside the sensing element, which effectively prevents environmental factors from affecting its performance.
Product Features
1. The sensor has a compact design, high measurement accuracy, fast response speed, and good interchangeability.
2. Suitable for all kinds of harsh environments.
3. Realize low cost and high performance.
4. The flange installation method is simple and convenient.
5. Reliable performance, ensure normal work and high data transmission efficiency.
Product Applications
This product is widely used in solar and wind power generation; solar water heaters and solar engineering; weather and climate research; agricultural and forestry ecological research; environmental science radiant energy balance research; polar, ocean, and glacier climate research; solar buildings, etc. that need to monitor solar radiation field.
