Photoelectric Pyranometer Application Areas and Technical Parameters

The Pyranometer(total solar radiation sensor) is an important ground meteorological observation instrument, but also an indispensable equipment in the field of solar energy resource census and photovoltaic power plant operation monitoring.

Common types of pyranometers are thermoelectric and photoelectric.

In order to meet the needs of customers, NiuBoL has designed two different types of solar radiation sensors, thermoelectric solar radiation sensors and photoelectric solar radiation sensors, so that customers can better choose to monitor the total solar radiation sensor according to their needs.

Photoelectric Pyranometer

NiuBoL Photoelectric Pyranometer (Model: NBL-W-HPRSL) adopts the principle of photoelectricity, which can be used to measure the solar radiation in the spectral range of 0.3~3μm. The Pyranometer adopts high-precision photoelectric sensing element, with wide spectral absorption, high absorption in the whole spectral range, and good stability; at the same time, it is equipped with a dust cover and high transparent dustproof cover, with a transmittance up to 95%, which are installed outside the sensing element. 

At the same time, the sensing element is equipped with a dust cover with a light transmission rate of up to 95%, a highly transparent dust cover with good sensitivity, and a special treatment of the dust cover to reduce the adsorption of dust and effectively prevent environmental factors from interfering with the internal elements, which enables it to accurately measure the amount of solar radiation. It also comes with a level and an adjustable handwheel, which is convenient for on-site adjustment.

The photoelectric Pyranometer adopts the standard Modbus-RTU 485 communication protocol, which can directly read the current solar radiation value, and the wiring is simple. Compact and beautiful appearance, occupies little installation space.
