A heat-flow sensor based on ac resistance thermometry and utilizing synchronous detection is described. The sensor design permits large-area sensors to be constructed economically. Calibration of an initial 0.09 m/sup 2/ prototype yielded a linear response with a sensitivity of (37.610.01) mV(W/m/sup 2/)/sup -/1. The minimum detectable heat flux is no larger than 0.08 W/m/sup 2/.
