      With this type of flame supervision, the changes in infrared radiation are used to generate the flame signal. The flame-detecting element is an infrared-sensitive photoresistor whose spectral sensitivity covers the range of approximately 1...3 µm. The detector does not respond to constant radiation or radiation with mains frequency harmonics (e.g. 50 Hz or multiples thereof). The suppression of these radiation frequencies is made electronically, directly dependent on the current mains frequency at which the relevant burner control (e.g. LMV5...) is operated
