Features: Measures direct solar irradiance from 300-4000 nm at normal incidence. A pyrheliometer consists of a radiation-sensing element enclosed in a casing (collimation tube) that has a small aperture through which only the direct solar rays enter. Date. The potential difference created in the thermopile owing to the temperature gradient between the two surfaces reveals information about the amount of solar radiation.

Commission for Instruments and Methods of Observation Fourteenth Session Geneva, 7 14 December 2006. Solar declination -23.4o. Principle: A steady wind speed, u, ... Laser Anemometer. These are also, commonly referred to as Parallel. Reference radiometers are maintained under an ISO 17025 accredited system of quality assurance. A pyrheliometer is an instrument used to measure the direct solar radiation at a given location. Solar declination -23.4o. strips are equal, the themocouple attached to the strips does not generate a current, since there is total compensation. The SHP1 has a response time under 2 seconds and individually tested polynomial temperature correction from -40°C to +70°C. The main working principle of this type of instruments is that, it senses the heat radiation from a targeted hot body and reads and records its temperature, depending upon the intensity of radiation. A thermopile consists of thermocouples, which are connected in series. AATS -14. Calibration. Sonic anemometers (10 30 m) ...
