A flueric nozzle-baffle combination for remotely measuring the surface temperature of either a stationary or moving object. The flueric nozzle opens to a sensing head which is preferably parallel to and opposed from the baffle surface of the object whose temperature is being measured. The back pressure of the fluid flowing through the nozzle is a function of the resistance to flow between the sensing head and the baffle which, in turn, is a function of temperature. If the distance between the sensing head and the baffle surface can be maintained constant, or can be measured by an auxiliary proximity sensor, the temperature may be computed as a linear function of sensed back pressure.
