How does a solar radiometer work
WebJun 14, 2024 · A pyranometer is a sensor that converts the global solar radiation it receives into an electrical signal that can be measured. Pyranometers measure a portion of the solar spectrum. As an example, the CMP21 Pyranometer measures wavelengths from 0.285 to 2.8 µm. A pyranometer does not respond to long-wave radiation. WebNov 25, 2014 · Give your Radiometer a gently but firm tap with two fingers directly on the very top of the bulb. Do not tap too hard as the bulb is made of thin glass. If the cup has simply dislodged itself from the needle this gentle impact may cause it to reset itself.
