Pyrheliometer for measuring solar radiation

NiuBoL Pyrheliometer -- A tool for accurate measurement of direct solar radiation

Pyrheliometer Product Overview:

The NiuBoL Pyrheliometer, a professional-grade solar radiation measurement device, is designed for high-precision measurement of direct radiation from the vertical solar surface (viewing angle of about 0.5°) as well as scattered radiation from the narrow ring of sky around the sun, which is a crucial aspect in the fields of meteorology, solar energy research, and agricultural science.

With its excellent performance and stable measurement capability, this direct radiation meter is committed to providing accurate and reliable direct solar radiation data for scientific research, meteorology, environmental protection and other fields.

Pyrheliometer technical parameters:

I. Product Principle and Structural Features

The NiuBoL Pyrheliometer adopts advanced design concepts and precise manufacturing processes to ensure the high performance and stability of the product. Its core components are the optical cylinder and the automatic tracking device, both of which work together to realize the precise tracking of the sun's position and the efficient collection of radiation. The following are its core principles and structural features:

1. Precision structure: the instrument is mainly composed of optical cylinder and automatic tracking device, which contains seven light columns, inner cylinder, thermoelectric stack and desiccant cylinder and other components to effectively reduce internal reflections and ensure measurement accuracy.

2. High-efficiency sensing capability: The light cylinder is equipped with a fast-responding wire-wound electroplated thermopile inside, and the sensing parts coated with non-glossy black paint can accurately capture the solar radiation and generate an electric potential proportional to the intensity of the radiation.

3. Environmental adaptability: Adopting JGS3 quartz glass sheet, it can transmit radiated light with wavelengths of 0.27-3.2µm, adapting to the measurement of direct solar radiation in various environments. Built-in desiccant prevents water vapor condensation to ensure measurement accuracy.

4. Thermopile Sensing: As the core of the sensing component, the wire-wound plated thermopile is known for its fast response speed and accurate measurement capability. Its surface is coated with a non-glossy black paint to maximize the absorption of solar radiation. When sunlight hits the hot contact of the thermopile, the temperature rises and creates a temperature difference with the cold contact, which generates an electromotive force proportional to the intensity of the direct solar radiation, allowing for accurate quantification of the amount of radiation.

Pyrheliometer use and maintenance                              

1, Pyrheliometer compared with other radiation meter, not only the sensing parts to be sensitive, but also tracking accurate in order to obtain accurate direct radiation. It is not easy to keep tracking the sun constantly, accurately and reliably under any weather conditions all year round, so it is necessary to strictly follow the operating procedures.

2, the beginning of each day's work should check the light cylinder quartz glass window is clean, such as dust, water vapor condensation should be timely with the suction ear ball blowing or with a soft cloth, optics lens paper wipe clean.

3、Monthly work should check a tracking situation, 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, in order to avoid damage.

5, Pyrheliometer used for more than two years, its sensitivity must be recalibrated by the manufacturer or measurement department.

As a manufacturer of measuring instruments, NiuBoL has always been committed to providing customers with high-quality, cost-effective, high-precision measurement solutions.NiuBoL Pyrheliometer, with its excellent performance, stable measurement capability and wide applicability, will certainly play an important role in the field of solar radiation research, choose NiuBoL Pyrheliometer.
