I have tried several optic flame sensors, but none of them work because the intensity of the light emitted by the flame is to small. The sensors I have tried work with an orange flame but not the small blue flame. I have been
thinking about using bare thermocouple wire and a temp control that can be configured to give a discrete output on temp rise. Anyone know of any device that will do this? I could amplify the thermocouple signal and go to an analog card, but that would require a PLC upgrade. Looking for a cheaper, easier solution.
