Pyranometer for Photovoltaic System Solar Radiation Sensor RS485 for Weather Station

 TBQ total radiation sensor adopts the principle of thermoelectric induction and works with various radiation recorders or radiation ammeters to accurately measure TBQ total radiation, reflected radiation, scattered radiation, infrared radiation, visible radiation, ultraviolet radiation, and long-wave radiation from the sun.

The core sensing element of the meter, a wire-wound plated multi-contact thermopile, is coated with a high absorbance black coating. The hot contact is on the sensing surface, while the cold junction is located inside the body, and the hot and cold contacts produce a temperature difference potential. The output signal is proportional to the solar irradiance over a linear range.

The double-layer glass cover is designed to reduce the effect of air convection on the radiation meter, and the inner cover is provided to cut off the infrared radiation from the outer cover itself.

Pyranometer for Photovoltaic System Solar Radiation Sensor Usage:  

Pyranometer for Photovoltaic System Solar Radiation Sensor is used to measure the total solar TBQ radiation in the spectral range of 0.3-3μm, and can also be used to measure the solar radiation incident to the oblique surface, such as induction face down can measure the reflected radiation, such as adding a shading ring can measure the scattered radiation. Therefore, it can be widely used in solar energy utilization, meteorology, agriculture, building materials aging and atmospheric pollution and other departments to do solar radiation energy measurement.

The solar radiation meter is a short-wave total radiation sensor for solar radiation observation applications. It meets the latest ISO and WMO standards for "Class I" meter specifications, and the accuracy of the measurement is consistent with KIPP&ZONE's Class II standard radiation meter.

The solar radiation meter is usually mounted horizontally, but it can also be mounted at an angle or upside down. In all cases, the sensor measures the amount of radiation incident on a plane parallel to the sensor surface.

Solar radiation meter installation location should have a wide field of view, especially in the sunrise and sunset orientation in the year should not be greater than 5 ° of the shade, optional on the ground or the roof platform, set up a special column or platform. For the upper part of the column fixed a piece of metal plate than the solar radiation sensor base is slightly larger than the contact surface with the instrument has good insulation.

The column platform is about 1.50m from the ground, requiring firmness, even if subject to severe shock vibration (such as high winds, etc.), does not change the horizontal state of the instrument.

Installation, first remove the white shield of the solar radiation table, and then install the total radiation sensor on the platform, so that the direction of the instrument terminals facing north.

Use screws to fix the instrument initially on the mounting plate, then use the level bubble attached to the instrument, adjust the adjustment foot on the base, so that the induction surface of the solar radiation table is in the horizontal state, then fix the mounting screws, and finally put the white shield on.
