Flame detector is used to monitor the gas flame, yellow or blue fuel combustion flame and spark ignition of proofreading.

This type of flame detector monitoring gas or fuel flame signals generated by the UV radiation emitted by flame.

Radiation detector is a UV photocell with two electrodes, when it was the 190 ~ 190 nm range in spectrum of light will be lit, so start the flame detection of the current in the circuit.
