Radiometers sensor locations

Thermopiles consist of very small fhermocouples joined fogefher in series. The heaf flows through the thermopiles and into a heat sink located just below. The difference in femperafure befween the sensor surface and heaf sink is a function of fhe heat being transferred and a function of the net absorbed heat flux [22]. The thermopile converts this flow of heat to an electrical signal that is then converted into a radiation level. Radiometers of this type do not require a power supply since the electrical output signal is generated by heat transfer. 

A set of at least two cubes are used to achieve the full capability of the instrument. The relative locations of the radiometer cubes and the flare, as well as the orientations of the cubes are determined prior to the flare test and entered into the computer to allow real-time tracking of key flare radiation parameters. Each radiometer on the cubes is connected to a data acquisition system. The data acquisition system collects the data from each sensor and performs trigonometric calculations using a complex set of equations. The results are real-time parameters of the flare radiation total radiation levels from both cubes, incidence angles, and the flare epicenter coordinates. This instrument has three main advantages over the handheld instrument ...
