GP Temperature Monitor/Infrared Sensor

Brand: Raytek

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 4–20 mA or thermocouple output. Two adjustable setpoints/deadbands control 5 V alarm outputs or optional 3 A 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.
