A pyranometer is a device used to measure the total solar radiation received from the sun. It is specifically designed to measure the intensity of solar radiation in watts per square meter (W/m²). A pyranometer consists of a flat, circular sensor that is sensitive to the full spectrum of solar radiation. It is typically mounted horizontally and calibrated to measure both direct and diffuse solar radiation. Pyranometers are commonly used in meteorology, solar energy research, agriculture, and environmental monitoring to understand solar energy availability and its impact on various processes.
Pyranometer installation Precautions #
- When the customer receives the product, please confirm the product model, etc.
- Do not wire with power on, and power on can only be done after the wiring is checked and correct
- The sensor is a precision device, please do not disassemble the glass cover at will
Pyranometer Troubleshooting #
- If the read value shows 0, check whether the protective cover of the product is removed and whether there is sunlight
- Please check if the 485 wiring is correct
- Check whether the power supply meets the mark
- Equipment damage
Pyranometer Maintenance #
a.The glass cover needs to be kept clean, and it is often wiped with a soft cloth or fur.
b.There should be no water in the glass cover. If it encounters heavy rain, snow, ice and other weather for a long time, it is recommended to cover it.
c.It is recommended to check whether the desiccant in the dryer becomes damp at regular intervals. The specific performance is orange to dark. If this happens, replace the desiccant in time, or remove the desiccant and put it back for use.
d.If the equipment has been used for more than two years, the sensitivity must be re-calibrated by the manufacturer or the measurement department.
FAQ #
Which level should i install a Pyranometer ? #
The recommended installation height of SEM228T is slightly higher than the ground plane, and the specific height depends on the site conditions.
Why does the Pyranometer photosphere have water or condensation? Why is the desiccant purple? #
Water or condensation occurs because the product is installed upside down. It should be installed horizontally with the ball facing up.
It is recommended to check whether the desiccant in the dryer becomes damp at regular intervals. The specific performance is orange to dark. If this happens, replace the desiccant in time, or remove and dry the desiccant before putting it back into use
