WebThis, of course, is undesirable, and monitoring this problem is necessary. When a heat flux sensor detects reduced heat flux, it signals to the user that the surface needs cleaning. Solar heat flux depends on the distance from the Sun, and it is approximately 426 Btu/h on Earth, and about 10,000 Btu/h in open space where the astronauts work ... A heat flux sensor is a transducer that generates an electrical signal proportional to the total heat rate applied to the surface of the sensor. The measured heat rate is divided by the surface area of the sensor to determine the heat flux. The heat flux can have different origins; in principle convective, radiative as well as … See more Heat flux sensors are used for a variety of applications. Common applications are studies of building envelope thermal resistance, studies of the effect of fire and flames or laser power measurements.
