TheThermalert®
GP'"Series
A versatile, two-piece temperature
monitoring system which 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 Lm 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 voltagefor 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 infrared sensor. This high performance, 8 to 14
micron infrared sensor with detachable cable combines
current loop driven signals with 35:1 optics. The GPM
sensor i s a miniature stainless steel sensing head
with 2:1 or 10:1 optics. The GP monitor also works with
other Raytek infrared sensors, including the Thermalert
CI.
