Detail intruduction

AWG SERIES heat flux sensor is a Gardon-type heat flux gauge with a circular constantan foil coated with absorbing coating attached to a copper heat sink. When the Gardon gauge is used to measure radiation flux, the thermal radiation is uniformly incident onto the gauge foil surface, and there is a temperature gradient in the radial direction so that the metal leads attached to the foil center and the edge form a thermocouple joint. The voltage output of the Gardon gauge from this thermocouple joint is linearly proportional to the incident heat flux in the steady-state heat flux conditions. The ratio of the voltage output to the measured heat flux is defined as the measurement sensitivity of the heat flux gauge。
