ABSTRACT:
A flame detecting device indicates the presence or absence of a flame. The detecting device includes both an IR detector for sensing the IR frequencies of the flame and a UV detector for sensing the UV intensity of the flame. Information is stored defining IR frequency and UV intensity standards. A microcomputer is operatively connected to the IR and UV detectors and compares the two detector outputs to the two respective standards in accordance with a program establishing defined conditions in terms of IR frequency and/or UV intensity that must be met for a flame present or flame absent signal to be rendered on a bar graph display.
