Pyranometer sensor

Pyranometer Sensor product overview:

A pyranometer sensor is a device used to measure solar radiation, specifically the total hemispherical radiation received from the sun. It is commonly used in meteorology, climatology, and solar energy applications. The word "pyranometer" is derived from the Greek words "pyr" (meaning fire or heat) and "ano" (meaning above or sky), indicating its purpose of measuring solar heat from the sky.

The sensor consists of a thermopile, which is a group of thermocouples connected in series. When solar radiation hits the surface of the sensor, it generates a temperature difference across the thermopile, creating a small voltage signal. This voltage signal is proportional to the solar radiation intensity and can be measured and recorded for various purposes.

Pyranometers are typically calibrated to provide accurate measurements of global horizontal irradiance, which represents the total solar radiation received from the entire hemisphere above a horizontal plane. Some advanced pyranometers may also provide additional measurements such as diffuse radiation and direct normal irradiance. These measurements are essential for assessing solar energy potential, studying climate patterns, and monitoring environmental conditions.

I. Pyranometer Sensor Product Principle and Features

Working Principle of Pyranometer Sensor

The Pyranometer Sensor is based on the thermoelectric induction principle, and its core sensing element is a wire-wound electroplated multi-contact thermopile. The surface of the thermopile is coated with a highly absorbent black coating to ensure maximum capture of solar radiation. When solar radiation hits the hot contacts of the thermopile, their temperature rises, creating a temperature difference with the cold contacts located inside the body, which in turn generates a temperature difference potential proportional to the intensity of the radiation. This electrical signal is then converted into a readable radiation intensity value.

The NiuBoL Pyranometer Sensor has the following distinctive features:

1. Efficient Measurement: The core of the sensor is a wire-wound plated multi-contact thermopile with a highly absorbent black coating to ensure efficient capture of solar radiation. The hot contact is located on the sensing surface and the cold contact is located inside the device, the temperature difference between the two produces an electrical signal proportional to the solar irradiance.

2. Stable and Reliable: The double glass cover design reduces the influence of air convection, and the inner glass cover effectively cuts off the infrared radiation from the outer glass to ensure the stability of the measurement results.

3. Multi-purpose applications: Pyranometer Sensor is suitable for measuring total solar radiation in the spectral range of 0.3-3μm, and can also be used for the measurement of oblique radiation, reflected radiation and scattered radiation.

4. Multiple output forms: It supports current, voltage and RS485 communication interface and other output methods, which is convenient to interface with various data acquisition systems.

5. Strong environmental adaptability: able to work stably in a wide range of temperatures and adapt to various climatic conditions.

Pyranometer sensors have an important role and value, especially in the fields of meteorology, climatology and solar energy applications. The following are their main roles and values:

1. Measurement of solar radiation: Pyranometer sensors are used to measure the total radiation from the sun, i.e. the solar radiation received from the entire hemispheric direction. This is important for understanding the intensity of solar radiation and how it varies.

2. Evaluation of solar potential: By measuring solar radiation, the solar potential of an area can be evaluated. This is of key importance in the design and planning of solar energy systems to ensure optimal energy yield.

3. Studying climate patterns: Solar radiation is an important component of the climate system. By using a pyranometer sensor, scientists can monitor changes in solar radiation and use this data for research and improvement of climate models.

4. Monitoring environmental conditions: Solar radiation is one of the most important factors affecting the environment and climate. By installing a network of pyranometer sensors, solar radiation levels in different areas can be monitored in real time, providing valuable data for environmental monitoring and weather forecasting.

5. Solar system performance evaluation: For systems installed with solar panels, pyranometer sensors can be used to monitor solar radiation levels and evaluate the actual performance of the solar system. This helps in determining system efficiency, troubleshooting and maintenance programs.
