Pyrheliometer

A Pyrheliometer is an instrument used to measure the intensity of solar radiation, especially direct solar radiation received at the Earth's surface. This device is commonly used in areas such as climate research, meteorological monitoring, solar energy efficiency assessment and environmental science.

Pyrheliometer technical parameters：

The pyrheliometer is an instrument for measuring direct solar radiation, which is mainly used in the fields of meteorological observation, solar resource assessment and scientific research. The following is the introduction of the pyrheliometer's product introduction, working principle and application scenarios: 

Pyrheliometer product introduction:

The pyrheliometer is a high-precision radiometric instrument for measuring direct solar radiation, which usually includes a sophisticated optical system and a radiation detector. The instrument can accurately measure the intensity and changes of solar radiation, providing important data support for solar energy use, weather forecasting and scientific research.

 How the pyrheliometer works:

The principle of operation of the pyrheliometer is based on receiving solar radiation and converting it into an electrical signal for measurement. By means of a sophisticated sundial device or tracking system, the pyrheliometer can keep the receiver and the direct sun rays in the same plane, so as to accurately measure the intensity of direct solar radiation.

 Introduction to pyrheliometer application scenarios:

1. Solar Resource Assessment: The pyrheliometer can be used to assess the solar resource of a specific area, providing important data support for the siting and design of solar power stations.

2. Meteorological Observation: pyrheliometers are used to monitor solar radiation at meteorological stations, climate research institutes and environmental monitoring stations to help understand climate change and insolation conditions.

3. Solar Radiation Research: pyrheliometers are used by scientific research organisations to study the patterns of change in solar radiation, geographical differences, and the impact on the Earth's environment and climate.

4. Performance evaluation of solar energy systems: For solar thermal power stations and photovoltaic power systems, the pyrheliometer can be used to evaluate the performance and efficiency of the system and guide operational adjustments.

In summary, the pyrheliometer, as a measuring instrument for direct solar radiation, has important application value in the solar energy field, meteorological observation and scientific research, providing users with key solar radiation data support.

Use and maintenance ：

1, direct Pyranometer compared with other Pyranometer, not only sensitive induction parts, but also accurate tracking, in order to obtain accurate direct radiation. It is not easy to keep constant, accurate and reliable tracking of the sun in any weather conditions all year round, so strict operating procedures should be followed.

2、The quartz glass window of the optical cylinder should be checked for cleanliness at the beginning of each day's work. If there is dust or water vapour condensation, it should be blown with an ear-sucking ball or wiped clean with a soft cloth or optical lens paper in time.

3、The work should be checked once a month for tracking and timely adjustment (to the light point).

4, the instrument is a precision instrument, in strict accordance with the operating procedures for debugging, never use excessive force, careful and light, reduce vibration, so as not to damage.

5, Pyranometer used for more than two years, its sensitivity must be re-calibrated by the manufacturer or measurement department.
