Description
CDG-11B PYRANOMETER SENSOR
The CDG-11B is a precision solar pyranometer sensor. It works based on the thermopile principle. The sensing elements are made by winding thermopiles that have many contacts. We coat its surface with a black material that absorbs a lot of light.
Hot contacts are on the surface of the pyranometer. The cold junction is located inside the body. The temperature difference between the hot and cold junction makes an electromotive force.
This thermoelectric effect is linked to solar radiation. To lessen the impact of ambient temperature, a temperature compensation circuit is designed. This circuit helps reduce the effects on product properties.

MAINTAIN
Regularly clean the sensor surface with a soft, lint-free cloth to remove dust, dirt, bird droppings, and other contaminants that may block radiation and affect measurement accuracy.
Inspect the leveling bubble and mounting bracket periodically to ensure the sensor remains horizontally installed and firmly fixed.
Check cable connections, wiring terminals, and waterproof joints to avoid loose connections, water ingress, or signal interruption caused by corrosion.
Avoid long-term shading of the sensor by trees, buildings, or shelters; trim surrounding obstructions if necessary to ensure a wide field of view.
Calibrate the solar radiation sensor at regular intervals using standard reference instruments to guarantee long-term measurement stability and accuracy.
Protect the sensor from physical impact, scratches, and extreme harsh environments such as heavy hail to prevent damage to the diffuser and internal components.
Drain accumulated water or snow on the sensor surface in a timely manner during rainy or snowy weather to maintain normal operation.
