<p>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.</p> |
