The total radiation sensor factory direct anti-radiation sensor solar irradiance sensor

The total radiation sensor FM-ZFS uses: This table is used to measure the spectral range of solar radiation 0.3-3μm, such as sensors for the measure under the reflected radiation, such as adding shade ring to measure the scattered radiation. Therefore, it can be widely used in solar energy, meteorology, agriculture, construction materials aging and atmospheric pollution and other departments to do the measurement of solar radiation energy. Structure and principle: This table thermoelectric effect principle, sensing element wound plating using multi-junction thermopile, its surface is coated with a black coating high absorption rate. Hot junction in the induction surface, and the cold junction is located in the body, hot and cold junction thermoelectric power generation. In the linear range, the output signal is proportional to the solar irradiance. To reduce the influence of temperature is equipped with a temperature compensation circuit, in order to prevent the environmental impact of its performance, use two layers of quartz glass, the cover is the result of precision optical cold ground into shape. Double glass in order to reduce the impact of air convection to radiation table. The inner cover to cover itself cut off infrared radiation of the word. Technical parameters: Sensitivity:. 7 ~ 14mv / kw.m-2 Response time: <30 seconds (99%) of the steady years: no more than ± 2% cosine response: no more than ± 7% (solar altitude 10 ° When) Temperature coefficient: less than ± 2% (- 25 ℃ ~ + 40 ℃) Spectral range: 0.3 ~ 3.2μm nonlinear: ± 2% weight: 2.5kg Signal output: 0 ~ 20mv use installation and maintenance.... : 1. Pyranometer is meteorological observation station radiation most commonly used instrument, the first consideration is the condition of the installation site, to make the glass dome cover half no obstructions so that the whole hemisphere of radiation comes from the sky, to ensure that barriers It was not shielded from the direct solar radiation, so the instrument due east and due west should have a good observing conditions. 2. The radiometers mounted horizontally on the observation platform so that the meter output plug north, leveled and fixed, then the summary table output lines connect the recorder. 3. Rain and hail should stop observing, wear protective cover. To ensure the data is accurate, observers should regularly clean the glass dust, silica gel desiccant found grain discoloration should be replaced.
