Radiation heat loss detector.

摘要: Need for a simple to use device that gives good estimates of heat loss from building or machines exists. This uses radiation and convection detector answer this need. Radiation an extended surface area as at (22) is detected with sensor (40) having wide field view closely matching associated camera (24). By simultaneously photographing the interest detecting same (22), clear record in Fig. 2 provided future use. A band used. Compensation environmental made by first viewing environment holding sensed signal then subtracting flux when faces area. The date time are also recorded on photograph 2. sonar (42) positioned provides distance indication which, known view, allows determination total convective losses correction atmospheric absorption radiant energy.
