The GP Series is a versatile, two-piece
temperature monitoring system that combines
a compact, value-priced monitor with an
infrared sensing head. The heart of the
system is the 1/8 DIN GP monitor which
provides advanced infrared processing
capabilities including peak and valley hold,
averaging, and a user-adjustable offset. The
rugged Thermalert GPR sensor is available
with standard or close focus optics, and
provides target temperature readings with
1% accuracy.
Along with its large 4-digit LED display, the
monitor provides a user-defined 4–20mA
or thermocouple output. Two adjustable
setpoints/deadbands control 5V alarm
outputs or optional 3A mechanical relays.
The GP monitor accepts universal 110–220
VAC power, and provides a 24 VDC/50 mA
excitation voltage for loop power to external
sensors. All monitor functions are configured
via the front panel, including °C/°F switching.
The GP monitor provides adjustable emissivity
and ambient compensation when used with
the GPR/GPS infrared sensors. These high
performance, 8–14 micron sensors, combine
current loop driven signals with high
resolution optics.
The GP monitor also works with other
Raytek infrared sensors, including the
CI, TX, MI and Marathon Series sensors.
