QFC Pyroelectric Flame Sensors

KEMET’s pyroelectric flame sensors provide a fast, stable response over a wide operating frequency range

Image of KEMET QFC Pyroelectric Flame SensorsKEMET's QFC pyroelectric flame sensors provide accurate discrimination of flame sources in triple IR flame detection systems, through their excellent signal-to-noise characteristic at the signature 8 Hz to 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 GΩ feedback resistor outputting a voltage signal centered around half the supply rail. Exceptionally high responsivity, a wide field-of-view, and rapid recovery from thermal and electrical shocks makes these sensors the ideal solution for demanding flame detection applications.
