Moll-Gorczynski Pyranometer (Kipp Solarimeter ...

· The Moll-Gorczynski pyranometer is a thermopile instrument, in which the receiving surface is covered by two concentric ground and polished glass hemispherical domes, 2 mm in thickness. The outer dome is removable and can be exchanged with filter domes. In the later models the necessary adjust­ments for cleaning and maintenance have been much facilitated.

Thermopile - Wikipedia

Thermopile infrared sensors are based on two physical effects: • Black body radiation: Any object with a temperature above 0 K emits electromagnetic radiation according Planck’s law. The integral over Planck’s curve is called the Stefan-Boltzmann-Law which gives the total emitted power:

DIGITAL THERMOPILE SENSORS

The thermopile infrared sensor consists of an absorber, which is thermally isolated from a frame and in series connected thermocouples. When the absorber is pointed towards an object with a temperature different from the absorber, then the power emitted by object and absorber differs as well. There is a netto radiative heat flow to/from the absorber which is heating/cooling the absorber. This ...

Thermopile Pyranometers – How Do They Work?

· The design, which was made up of several thermocouples, was by Dr. Moll of Utrecht University. Dr. Moll’s thermopile prototype drew the attention of several scientists in a meteorological conference at Utrecht in 1923. Following that, Professor L. Gorczynski of the Polish Meteorological Institute constructed a pyranometer and a pyrheliometer after modifying Moll-Gorczynski thermopiles.
