PY-ITV-FLAME TO39(2+1) (REV. 5.0) Thin Film Pyroelectric Flame Sensor Introduction The Pyreos thin film pyroelectric 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). 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 10G feedback resistor outputting a voltage signal centred around half the supply rail.
