D-GT 800 Flame sensor
D-GT 800 Flame sensor
D-GT 800 Flame sensor (flame scanner) for monitoring gas, oil and coal flames, primarily in single burner view applications.
With its combination of a highly sensitive photo element and sturdy design, the D-GT 800/801 flame sensors are ideal for use in harsh environments such as in gas turbines. The photodiode used can detect almost all blue burning flames, such as gas flames having only a low radiation component in the visible range. The D-GT 800/801 is available with different photo elements for optimal selectivity when using different fuels.
