Compact Series CI

The CI Series Compact Infrared Sensors
accurately and repeatably measure the amount
of heat energy emitted from an object and
convert the energy into a measurable electrical
signal. The CI measures target temperatures
ranging from 0 to 500°C (32 to 932°F).
The onboard electronics are protected by
a rugged IP 65 (NEMA-4) stainless steel
housing, allowing the sensor to function
in ambient temperatures to 70°C (160°F)
without cooling. With water cooling, the
CI can withstand ambient temperatures up
to 260°C (500°F).
Features:
Type J or K, or 0-5 V output
Two models cover temperature ranges from
0ºC to 500°C (32ºF to 932°F)

Compact Series MID

The MID is a two-piece infrared temperature
measurement system with a miniature sensing
head and separate electronics. The sensor,
small enough to be installed just about
anywhere, performs as well as much larger
systems. The MID signal processing electronics
include Emissivity, Peak Hold, Valley Hold,
and Averaging functions, that you adjust
on the 5-digit LCD user interface.
Features:
Temperature ranges:
- Model LT -40 to 600°C(-40 to 1112°F)
- Ambient operating range to 85°C(185°F)
without cooling
- Small sensing head fits where other sensors
can't - 5-digit backlit LCD user interface
- 1% accuracy
- 10:1 optical resolution
- Powered by 12-24 VDC at =100 mA
- Accessories for cooling and air purging
- Remote electronics box
- NEW! Standard RS-232
communications for remote setup and monitoring
- Optional RS-485 communications for remote
setup and monitoring of multidrop network
- supports up to 32 sensors

MID
Compact Series GP

The GP Series is a versatile, two-piece
temperature monitoring system that combines
a compact monitor and an infrared sensing
head. The heart of the system, the 1/8 DIN
GP monitor, provides advanced infrared processing
capabilities including peak and valley hold,
averaging, and a user-adjustable offset.
The rugged Thermalert GPR/GPS sensors are
available with standard or close focus optics,
and provide target temperature readings
with 1% accuracy. The Thermalert GPM is
available with preinstalled cable.
Features:
- Temperature range from -18 to 538°C
(0 to 1000°F)
- NEW! GPS Laser Sighted
Head (Click here to learn more about this
feature)
- Compact 1/8 DIN digital monitor with large
4-digit display
- Monitor and sensor functions configured
on front panel
- Signal processing capabilities typically
found on much larger systems
- Adjustable emissivity and t-ambient parameters
- Universal 110-220 VAC power included
- User-defined 4-20 mA or thermocouple output
(J, K, E, N, R, S, T)
- Adjustable dual setpoints and deadband
alarm outputs
- Choice of sensing head to match application
requirements
- Standard and close focus optics available
- Accessories for cooling and air purging
- Field interchangeable sensing heads

ST Series™ - Noncontact
Portable IR Thermometers

The professional's diagnostic tool.
With a broader temperature range and improved
optics for measuring temperatures from a
greater distance or measuring smaller objects
from the same distance, the STPro series
offers a combination of accuracy and value
for professionals. Standard features also
include a rugged rubber overmolding and
a durable plastic storage case. Special
models include: AutoPro for automotive applications
and ST80 XB-IS for hazardous environments
applications.
The ST models feature the Extra Bright
Single Point laser sighting system. The
Extra Bright laser sighting system concentrates
all of the laser energy in a single point,
showing the center point of the measurement
area more visibly in all conditions, especially,
outdoors.
Suggested Applications:
Plant/General Maintenance Applications
HVAC/R Applications
Transportation/Automotive Applications (AutoPro
Model)
Hazardous Environments Applications (ST80
XB-IS Model)
Optional accessories include a soft pouch
and RTD probe (ST60 XB, ST80 XB, ST80 XB-IS).
