Product Overview
The Broadcom Thin Film Pyroelectric Flame Sensor is a high-responsivity infrared flame detector designed for accurate flame source discrimination. It features a wide field of view (typically 100) and rapid recovery from thermal and electrical shocks (<1 second downtime). This current mode sensor offers excellent signal-to-noise ratio at the characteristic 8-10 Hz flicker range of flames, making it suitable for triple IR flame detection systems. The sensor integrates a low-noise circuit with an internal CMOS op-amp and a 10G feedback resistor, outputting a voltage signal centered around half the supply rail.
