SINGLE CHANNEL
PYROELECTRIC DETECTOR
Introduction
The Pyreos thin film pyroelectric gas
detectors offer exceptionally high
responsivity, low microphonics and class
leading thermal and electrical stability.
This high performance detector achieves a
signal to noise of ~10,000 and offers a
fast, stable response over a wide
operating frequency range. The sensor
element is built into a low noise circuit that
has an internal cmos op amp, with a 10 G
Ohm feedback resistor outputting an
industry standard voltage mode signal.
The standard pin-out makes it a simple
replacement for leading voltage mode
devices.
