Linear systems design and offer burner programmers, burner controllers and programmable sequence controllers which are preprogrammed to ensure the automatic working of gas/oil burners. They assist in managing safe start up of the burner and continuously monitor of the flame. These systems provide output for blower, ignition, solenoid valves etc. with prefixed timings for continuous flame supervision. Linear systems has burner sequence controllers for oil fired burners, gas fired either UV flame sensing burners or flame rod sensing. Burner controllers 107 M/S-FO/S-60/S-30/TU/P6 and LS-107 are from 100 series controllers that work for boilers or oil fired burners. Similarly 300 series controllers work for UV flame sensing gas burners. And 200 series is used for flame rod sensing gas burners.
