Product Overview
Broadcom thin film pyroelectric infrared flame detectors offer exceptionally high responsivity and a wide field of view, typically 100. These current mode sensors provide rapid recovery from thermal and electrical shocks (typically <1 second downtime) and excellent signal-to-noise ratio at the characteristic 8-10 Hz flicker range of a flame. They are designed for accurate discrimination of flame sources in triple IR flame detection systems. The sensor element is integrated into a low-noise circuit featuring an internal CMOS op-amp with a 10G feedback resistor, outputting a voltage signal centered around half the supply rail.
