TBQ-2C pyranometer solar radiation sensor
The TBQ-2C pyranometer solar radiation sensor is an integrated Class 1 radiometer designed to measure total solar radiation in the 0.3–3.2 μm wavelength band. It employs a fast-response wire-wound thermopile as its core sensing element, with the sensing surface coated in 3M matte black paint. This configuration precisely converts the thermoelectric potential generated by solar radiation into electrical signals. Its dual-layer quartz glass dome structure effectively suppresses air convection interference. The inner and outer dome design minimizes self-radiation effects, ensuring stable and high-precision radiation measurements. This solar radiation is highly suitable for applications including meteorological monitoring, environmental observation, and photovoltaic assessment.

Introduction
The TBQ-2C Total Radiation Pyranometer is primarily used as a Class 1 instrument for measuring total solar radiation within the wavelength range of 0.3–3.2 micrometers. This pyranometer consists of a double-layer quartz glass cover, sensing elements, a sunshield, and a desiccant chamber within the housing. The following sections will illustrate its key structural components, providing a clearer understanding of the product’s internal construction and fundamental performance characteristics.
Structure of pyranometer solar radiation sensor
- Double-layer quartz glass cover: The outer cover minimizes temperature fluctuations caused by air convection, while the inner cover blocks infrared radiation emitted by the outer cover itself.
- Sensing Element: Utilizes a wire-wound, electroplated, fast-response thermopile. The sensing surface is coated with 3M matte black paint. When exposed to sunlight, the temperature rises, creating a thermoelectric potential difference with the cold junction on the opposite side. This potential difference is directly proportional to the intensity of solar radiation.
- Light shield: Used for periodic calibration and zero-point testing, it blocks incident radiation to ensure measurement accuracy.
- Desiccant in the housing: Maintains a dry internal environment, prevents fogging on the inner surface of the glass cover, and enhances long-term optical transmittance.

solar radiation sensor working principle
The weather station solar radiation sensor measures solar radiation intensity by absorbing sunlight and converting it into heat. An internal thermocouple then transforms the resulting temperature difference into an electrical signal. A double-layer quartz glass cover minimizes environmental interference, ensuring stable and reliable measurements. The following provides a concise overview of its operating principle to help you better understand the sensor’s functionality.
- Absorbing sunlight: The black coating on the sensor surface rapidly absorbs sunlight, converting light energy into heat.
- Generating a temperature difference: The sensing surface heats up while the opposite side remains cooler, creating a temperature gradient between them.
- Generating an electrical signal: The internal thermopile generates a weak voltage due to the temperature difference, with the voltage magnitude being directly proportional to the intensity of sunlight.
- Glass cover protects measurements: The double-layer quartz glass cover minimizes the effects of air convection and self-infrared radiation, ensuring more stable and accurate measurements.
- Outputting radiation values: The system calculates the total solar radiation intensity based on voltage changes, ultimately outputting stable and reliable data.
