The Kemet QFC pyroelectric flame sensors provide accurate discrimination of flame sources in triple IR flame detection systems, through its excellent signal to noise characteristic at the signature 8 – 10 Hz flicker range of a flame. The sensor element is built into a low noise circuit that has an internal CMOS op amp with a 10 GO feedback resistor outputting a voltage signal centred around half the supply rail. Exceptional high responsivity, a wide field of view and rapid recovery from thermal and electrical shocks makes it the ideal solution for demanding flame detecting applications.
