Product Description

BGT CLASS B PV Monitoring solar radiation Detector Total Solar Irradiance Sensor for Photovoltaics Plants

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.
TBQ total radiation 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, so the sensor has high measurement accuracy.
The use of the TBQ total radiation sensor is very simple. You only need a high-precision voltmeter to read the measurement data. When calculating incident irradiance, the output voltage is divided by the sensitivity. Each sensor will provide corresponding sensitivity data when it leaves the factory. The TBQ total radiation sensor can be connected to most commonly used data acquisition systems. The TB total radiation sensor can be used for meteorological observations, building physics, climate and solar light collection experiments. A common application is as part of a weather station to measure outdoor solar radiation

Features

TBQ total radiation sensor uses the black coating on the sensor to absorb solar radiation. The radiation is converted into heat energy and enters the interior of the sensor, forming a temperature difference at both ends of the thermopile, thereby generating a voltage output signal proportional to the incident solar radiation.
 

Product Parameters

The TBQ series total radiation sensor is used to measure the solar radiation received by the horizontal plane from a solid angle of 2π steradians (hemispheric direction), in W/m2. The TBQ total radiation sensor adopts a completely passive working mode, using the black coating on the sensor surface to absorb incident solar radiation and convert it into heat energy, creating a temperature difference at both ends of the sensing device, thereby generating a radiation that is proportional to the amount of incident radiation. the output voltage.
