Thin Film Pyroelectric Flame Sensor
Introduction
The Pyreos thin film pyroelectric flame sensors offer
exceptionally high responsivity, a wide field of view of
typically 100 degrees (*subject to filter band pass
specification) and class leading rapid recovery from thermal
and electrical shocks (<1 second downtime). This 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
internal cmos op amp provides enhanced stability and
reliability. It has an industry standard pin-out and voltage
mode output signal.
