The SPECTRA PRO's frequency discrimination feature allows it to filter out background radiation from hot, glowing boiler walls and also radiation interference from neighboring burners or pilots. This discrimination capability ensures that when a flame is extinguished, the relay trips immediately because there are no background radiation effects that could provide a false flame on condition.
All of the functionality of the SPECTRA PRO is easily programmable using AMETEK's AmFlame PC interface software. In addition to configuration, AmFlame provides real time monitoring of the flame sensor output and the condition of the three output relays. AmFlame will also keep track of all program setting, changes and can record sensor output data for analysis.
