ABSTRACT:
A thermoelectric sensor assembly 1 for use with a flamestrip 9 in a fuel gas burner. The sensor assembly may be in the form of a probe 2 having temperature sensors 5a,b,c,d downstream of the flamestrip 9 in and adjacent the flame region, and temperature sensors 6a,b,c upstream of the flamestrip. A voltage output signal from the sensor assembly is used as an indication of the aeration of the flame and/or of flame establishment and/or flame failure and/or flame lightback.
