Introduction

Direct solar radiation is radiation from the surface of the sun (about 0.5° viewing angle) and the narrow sky around the sun. Direct radiation plays an important role in meteorological research and solar resource utilization. The direct radiation meter is an instrument for measuring direct solar radiation. At present, China has a variety of direct radiation phenotypes, with the World Meteorological Organization and the State. There are still inconsistencies between the standard documents, which is not conducive to the unification of the measured values. This standard is specially formulated to regulate the production of direct radiation meters. And inspection. The direct radiation meter in this standard is an analog output instrument, which is connected to the electrical measuring instrument and installed on the automatic solar tracker. The amount is directly radiated. Direct radiation meter

1 Scope

This standard specifies the technical requirements, test methods, inspection rules, marking, packaging, transportation, storage and products of thermoelectric direct radiation meters. Complete sets and so on. This standard applies to the design, production and inspection of thermoelectric direct radiation meters.

3 Terms and definitions

The following terms and definitions apply to this document. 3.1 Direct radiation directradiation Direct solar radiation direct solar radiation; beamsolarradiation Radiation from a small solid angle around the sun and its surroundings. Note. In general, direct solar radiation is measured by an instrument with an angle of view of approximately 5°. Therefore, it includes part of the scattered radiation around the sun, that is, the ring radiation, and The field of view of the day itself is only about 0.5°. ......
