Raytek’s compact temperature monitoring systems are
easy to both install and integrate into an existing process control
system. The centerpiece of this system is the 1/8 DIN Thermalert®
GP™ monitor which provides a standard interface for Raytek sensing
heads including the Thermalert GPR or GPM. If a separate monitor
is not required, the two-piece Thermalert MID sensor, or the integrated
Thermalert CI sensor, provides compact solutions to infrared temperature
monitoring.
When
panel space is tight, the GP 1/8 DIN monitor gives you the benefits
of non-contact infrared temperature measurement with no reduction
in accuracy. Combined with the GPR or GPM sensing heads, the GP
monitor system provides on-going temperature readings with a superior
1% accuracy. Adjustable offset and two adjustable setpoints with
alarm outputs for tight process control are features used in the
GP system along with being able to configure all monitor and sensor
functions from the front panel. The large, 4-digit, easy-to-read
display assists in taking readings at a glance.
This versatile GP system allows for the configuration of an infrared
temperature monitoring system that best matches the application.
If the sensor head is located near the measurement target, or
the target is large, the GPM or CI is appropriate. If the measurement
spot is small, or the sensor must be located further from the
target, the GPR with 35:1 optics is required. The GP sensing heads
range from the small to the miniature allowing you to place sensors
anywhere. With the prices as low as they are, enhanced monitoring
coverage can be accomplished by installing these sensors at multiple
points throughout the process.
As a low maintenance solution for thermocouples, the Thermalert
MID or CI may fit the bill. The two piece MID system with miniature
sensing head and separate electronics, features adjustable Emissivity
and selectable Peak Hold, Valley Hold and Averaging. The CI is
a compact, integrated unit with the same output impedance as a
thermocouple. It functions without offset error when used in tandem
with the thermocouple break-protection circuitry in most controllers,
displays and transmitters. Both the MID and the CI are encased
in rugged housings which ensure continuous, long-term performance
in environments with high ambient temperatures.
