A solar pyranometer is a device specifically designed to measure solar irradiance or radiation from the sun. It is used in various fields such as climatology, weather monitoring, solar energy research, agriculture, and environmental monitoring. Pyranometers measure the total solar radiation received over a flat surface, including both direct and diffuse sunlight. They are calibrated to provide accurate measurements and can be used to analyze solar energy potential, monitor weather patterns, optimize irrigation scheduling in agriculture, and assess the environmental impact of solar radiation. Pyranometers are an essential tool for studying and harnessing the power of the sun.
Solar pyranometer troubleshooting #
① If the read value shows 0, check whether there is a light source, and check whether the product protective cover is removed
② The 485 bus is disconnected, or the A and B lines are reversed
③ Check whether the power supply conforms to the label
④ Equipment damage
⑤ Output or output error Reply frame
Solar pyranometer possible reason #
a. The wiring method is incorrect or the wiring sequence is wrong.
b. The power supply voltage is wrong (for the 0-10V type, the power supply is 24V).
c. The distance between the transmitter and the collector is too long, causing signal disorder.
d. The data acquisition port is damaged.
e. Equipment damage.
Solar pyranometer maintenance #
1. The dust cover needs to be kept clean and wiped with a soft cloth regularly
2. There should be no water in the dust cover. If it encounters heavy rain, snow, ice and other weather for a long time, it is recommended to cover it.
