Noncontact Temperature
Measurement
Watlow offers a wide variety of
Raytek®infrared thermometers that
monitor and control temperature in
various manufacturing processes.
These thermometers measure
temperature of fast moving
processes quickly and efficiently.
They measure the temperature of the
product directly, instead of the oven
or the dryer. This allows you to
quickly adjust to process parameters
to ensure top product quality.
Infrared thermometers are easily
integrated into existing process
control systems and have the
following benefits:
• Non-destructive: the product is
never touched or contaminated
• Fast and reliable: moving objects
are measured accurately and
quickly
• Flexible: temperature
measurements can be made of a
large area or a small spot
Small Size, Big Features
These products may be compact,
but do not compromise on features.
Using advanced micro-fabrication
techniques, the cost and size of
these sensors remain small while
retaining sophisticated features such
as emissivity, signal conditioning
and t-ambient processing. The wide
temperature range in each model
allows you to detect process
variations and monitor start-up
performance.
Infrared Thermocouples
If you are looking for a low-
maintenance solution for infrared
thermocouples, consider the MI™ or
CI™. The MI™, a two-piece 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
accurately—without offset errors—
when used in conjunction with the
thermocouple break protection
circuitry in most controllers, displays
and transmitters.
Both the MI™ and CI™ have rugged
stainless steel housings to ensure
continuous, long-term performance,
even in environments with high
ambient temperatures.
An Affordable Solution for
Your Process
The miniature size and low cost of
the MI™ (shown above) make it an
ideal configuration for installation at
multiple points along your process.
The sensor is isolated from the
electronics box which allows it
to withstand ambient temperatures
up to 200°C (392°F) with cooling
accessories.
Whether you choose a modular system
based on the GP™ monitor, or the
MI™ or CI™, we have a compact,
value-priced infrared thermometer to
meet your needs. Cooling jackets, air
purge collars and other accessories
are available to ensure accurate
performance regardless of your
environment.
Raytek®Service Ensures Long
Use
With over 30 years experience,
Raytek®knows infrared temperature
measurement. Application
specialists are available to help
answer your technical questions.
Each product includes a two year
warranty. In addition, maintenance,
training, calibration and other
customized services are available to
ensure that you receive the
maximum benefits from your Raytek®
infrared, noncontact thermometer.

Raytek®GP™ Sensor
The GP™ sensor is 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 1⁄8DIN GP™ monitor
which provides advanced infrared
processing capabilities including
peak and valley hold, averaging
and a user-adjustable offset. The
rugged GPR sensor is available with
standard- or close-focus optics
and provides target temperature
readings with one percent accuracy.
Along with its large four-digit LED
display, the monitor provides a user-
defined 4-20mA or thermocouple
output. Two adjustable set points/
deadbands control 5V alarm outputs
or optional 3A mechanical relays.
The GP monitor accepts universal
110-220VÅ(ac) power and provides
a 24VÎ(dc)/50mA 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 when used
with the GPR™ infrared sensor. This
high performance, eight to 14 micron
infrared sensor with detachable
cable combines current loop driven
signals with 35:1 optics.
The GP™ monitor also works with
other Raytek®infrared sensors,
including the CI™ and MID™.

Raytek®GP™ Monitor
The GP™ monitor provides a
compact, easy-to-use interface and
display for process instruments.
This low-cost 1⁄8DIN digital panel
meter comes standard with features
which are optional on other panel
meters in this price range. The GP™
monitor accepts inputs from any
0-5V sensor, 4-20mA sensor or
thermocouple type J,K,E,N,R,S,T.
In addition, the monitor can be
used with many Raytek®noncontact,
infrared temperature sensors.
Along with it’s large four-digit LED
display, the monitor provides a
user-defined 4-20mA or thermo-
couple output. Two adjustable set
points/deadbands control 5V alarm
outputs or optional 3A mechanical
relays. The GP™
monitor accepts 110-220VÅ(ac)
power and provides a 24VÎ(dc)/50
mA excitation voltage, capable of
providing loop power to external
sensors.
For signal processing requirements,
the monitor provides peak hold,
valley hold and averaging and a
user adjustable offset. Best of all,
there are no internal jumpers used
for setup, as all monitor functions
are configured via the front panel.
Versatile. Compact. Value-priced.
All reasons to standardize on the
GP™ monitor for your process
monitoring requirements.

Raytek®MI™ Temperature
Measurement System
The MI™ product is a two-piece
infrared temperature measurement
system with miniature sensing head
and separate electronics. The
sensor is small enough to be
installed just about anywhere, yet
performs as well as much larger
systems. The MI™ electronics
include a host of signal processing
features which you won’t normally
find in systems in this price range,
including emissivity, peak hold,
valley hold and averaging, all of
which are adjustable on the five-digit
LCD interface.
Designed for applications where the
target temperature is in the -40 to
600°C (-40 to 1112°F) range, the
sensor is housed in a rugged
stainless steel enclosure to ensure
long term performance, even in
harsh industrial environments with
ambient temperatures up to 85°C
(185°F) without cooling.
Although the MI™ system is small in
size, it still has the features you
need, with one percent accuracy
and 10:1 optics, with user selectable
output signals. And the MI’s™
response time is as fast or faster
than many high-end systems.
The MI’s™ system’s miniature size
and low cost make it ideal for
installation at multiple points along
your process. Accurate. Easy to
install. Affordable. With the MI™
system, precision infrared
temperature measurement is now an
economical alternative.

Raytek®CI™ Sensor
The CI™ sensor provides the
advantages of infrared temperature
measurement in a compact, low cost
integrated sensor. Designed for easy
integration into a standard four-wire
system, the CI™ sensor can easily
replace traditional contact probes
with a Type J or Type K
thermocouple output, or with a 0-5
volt output if your application is
susceptible to noise or requires a
longer cable run.
The CI™ sensor is designed to
measure target temperatures ranging
from 0 to 500°C (32 to 932°F). The
CI’s™ onboard electronics are
protected by a rugged IP 65 (NEMA-
4) stainless steel housing and the
sensor can function in ambient
temperatures to 70°C (160°F) without
cooling. With water cooling, the CI™
sensor can withstand ambient
temperatures to 260°C (500°F).
Because the CI™ sensor has the
same 50 ohm output impedance as a
thermocouple, it functions
accurately—without offset errors—
when used in conjunction with the
thermocouple break protection
circuitry in most controllers, displays,
and transmitters.
Compact. Easy to install. Affordable.
The CI™ sensor is ideal for both
OEM and end-user applications.
