QFC Pyroelectric Infrared Flame Sensors, Analog
Overview
Applications
KEMET’sꢀQFCꢀpyroelectricꢀflameꢀsensorsꢀprovideꢀaccurateꢀ
discriminationꢀofꢀflameꢀsourcesꢀinꢀtripleꢀIRꢀflameꢀdetectionꢀ
systems, through its excellent signal to noise characteristic
atꢀtheꢀsignatureꢀ8ꢀ–ꢀ10ꢀHzꢀflickerꢀrangeꢀofꢀaꢀflame.ꢀTheꢀ
sensor element is built into a low noise circuit that has
anꢀinternalꢀCMOSꢀopꢀampꢀwithꢀaꢀ10ꢀGΩꢀfeedbackꢀresistorꢀ
