PURPOSE
Measurement of the radiation balance of the surface under study in natural conditions, that is, the difference in the values of irradiance (radiation) created by the fluxes of solar and thermal radiation entering on its receiving surfaces. Operating principle of Net Radiometer is based on thermal-to-electrical energy conversion. Under the influence of solar and thermal radiation entering on the blackened receiving surfaces of the sensitive element, an electromotive force (hereinafter referred to as EMF) of direct current is generated in the thermobattery, which is proportional to the difference in the values of the irradiance of the receiving surfaces (i.e., the radiation balance). The analog signal from the radiation balance converter enters onto the input of the analog-to-digital converter of the electronic unit, is converted into digital form and then enters to the RS-485 interface converter connected to the PC. The information on PC is displayed by means of «Peleng Meteo» software. When using the electronic radiation balance converter, the digital signal via the RS-485 interface enters directly to the PC through the interface converter. The information on the PC is displayed by the “Peleng Meteo Actinometry” software.
