Qwertour Integrated Rainfall Monitoring Station, Automatic Weather Station, Wireless Agricultural Meteorological Rainfall Observation Station
Working principle: The meter is based on the principle of thermoelectric effect. The sensing element adopts a wire-wound electroplating multi-contact thermopile, and its surface is coated with a black coating with high absorptivity. The hot junction is on the sensing surface, and the cold junction is located in the body, and the hot and cold junctions generate a thermoelectric potential. In the linear range, the output signal is proportional to the solar irradiance. In order to reduce the influence
In order to reduce the influence of temperature, it is equipped with a temperature compensation circuit. In order to prevent the influence of the environment on its performance, a two-layer quartz glass cover is used, which is made by a precision optical cold processing.
Instructions for use: The meter should be installed in an open surrounding area without any obstacles above the sensing surface. Then place the radiometer cable plug directly to the north, adjust the horizontal position, and fix it firmly, and then connect the total radiometer output cable with the recorder to observe. Fix the cable firmly on the mounting frame to reduce breakage or intermittent interruption on windy days.
Uses/applications: This meter is used to measure the total solar radiation with a spectral range of 0.3-3μm, and it can also be used to measure the solar radiation incident on the slope. If the sensing surface is facing down, it can measure the reflected radiation. If the light-shielding ring is added, it can measure the scattered radiation. . Therefore, it can be used in solar energy utilization, meteorology, agriculture, building material aging and air pollution, and other departments to measure
the environment on its performance, a two-layer quartz glass cover is used, which is made by a precision optical cold processing.
