DigiPyro^™ Triple Channel
Quad Element Detector, PYQ 2898
World’s first digital Quad Element pyrodetector.
The new DigiPyro™ Triple Channel is making another step-change in digital motion detection.
Overview
The Triple Channel, PYQ 2898, is
the newest addition to the growing
DigiPyro™ family of digital pyro-
electric infrared detectors, brought to
you by PerkinElmer.
The Triple Channel Quad Element
detector is the high end version of
the DigiPyro family, with two pairs
of elements representing two chan-
nels and an additional temperature
reference channel. It is a quad ele-
ment configuration which is connec-
ted to a special integrated circuit.
It contains the analog-to-digital con-
verter, a temperature sensor, the
low-power oscillator and a serial
interface, all in a standard three-pin
TO-5 housing. It offers a 42 bit
”direct link” interface.
The move from analog to digital
technology enables the DigiPyro to
deliver a number of advantages
including space savings from fewer
components and significantly
improved EMI immunity.
The PYQ 2898’s fully digital, inte-
grated processing technology con-
tinues the high quality standard
tradition that customers have come
to rely upon with the Dual Element
PYD 1998 and all analog pyrodetec-
tors PerkinElmer offers.
With the addition of the PYQ 2898
to the DigiPyro family, PerkinElmer
is making another step-change in
digital motion detection, for the
first time enabling low-cost, quad
element systems.
