PY-ITV-DUAL–T039(3+1)

DUAL 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
elements are 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.
With a standard pin out it makes it a
simple replacement for leading voltage
mode devices.
