Parameters

Description:

The total radiation sensor is based on the principle of thermoelectric effect. It adopts a winding electroplating multi-node thermopile with a black coating with high absorption rate. When there is light, the temperature difference between the hot and cold contacts is generated, which generates a potential difference, and then converts the light signal into an electrical signal output. Within the linear error range, the output signal is proportional to the solar radiation. The radiation meter has an integrated temperature compensation device, which can automatically compensate the output potential of the radiation meter by adjusting the temperature coefficient of the thermistor.
