Broadcoms thin film pyroelectric infrared flame detectors offer exceptionally high responsivity, a wide field of view of typically 100° (*subject to filter band pass specification) and class leading rapid recovery from thermal and electrical shocks (<1 second downtime). The analog single detector AFBR-S6PY3200 is equipped with a 2.77 µm / 690 nm bandpass filter with typ. cut on wavelengths at 2.425 µm and typ. cut off wavelengths at 3.115 µm. This current mode sensor has excellent signal to noise at the signature 8-10 Hz flicker range of a flame, and can provide accurate discrimination of flame sources in triple IR flame detection systems. The sensor element is built into a low noise circuit that has an internal CMOS op amp with a 10GΩ feedback resistor outputting a voltage signal centered on half the supply rail.
