BGT CLASS B PV Monitoring Total Solar Irradiance Sensor
The TBQ total radiation sensor is a short-wave total radiation sensor used for solar radiation observation. It is a first-class total radiation sensor that complies with the latest ISO9060 and WMO technical standards.
This sensor is used to measure the solar radiation received by the horizontal plane from a solid angle of 2π steradians (hemispheric direction). The unit is W/m². The TBQ total radiation sensor operates completely passively, using a thermopile sensor to generate an output voltage proportional to the incident radiation flux. Due to the use of two spherical glass covers, measurement errors, especially thermal offset, are reduced, ensuring high measurement accuracy.
The sensor utilizes a specialized black coating to absorb solar radiation. This radiation is efficiently converted into heat energy, creating a temperature difference at both ends of the thermopile. This process generates a voltage output signal directly proportional to the incident solar radiation, allowing for precise measurement in PV monitoring and meteorological applications.
