Noncontact Temperature Measurement for Industrial Applications

Safe Smart Versatile

Fast Measurements

MI3 Series – Smart and Innovative

Infrared thermometers measure the energy
radiated from an object, without touching it.
This measurement technique is important in
applications where contact would damage or
alter the surface, such as a sheet of plastic
film; or contaminate the product, such as food
processing.

Unlike contact sensors, there is no delay while
the infrared thermometer reaches the correct
temperature. This makes it ideal for measuring
moving or discrete processes. The result
is fast, accurate noncontact temperature
measurement and tighter control of your
process.

Standard Features MI3

■

Extended temperature range up to 1650 °C
(3002 ºF)

■

Optical resolution up to 22:1

■

Dedicated close focus lens for spot sizes
down to 0.5 mm (0.02 in)

■

Short response time down to 20 ms

■

Industrial rugged cable: Silicone and Halogen

free, resistant against oil, bases, and acids

■

USB 2.0 interface as standard and

selectable field busses

■

Ambient temperatures up to 180 °C (356 °F)
without the need for costly cooling

Most IR temperature sensors on the market transfer
measurements from the sensing head to the electronics as
interference-prone analog signals in a very sensitive µV range,
the MI3 models allow calibrated, digital temperature output
directly from each sensor head.

MI3 – The World’s Smallest
Stand-alone Pyrometer

The Raytek® MI3 is a rugged, IP65 stainless steel miniature
pyrometer with integrated electronics that can measure a wide
range of temperatures. Just 14 mm (0.55 in) in diameter and

28 mm (1.1 in)
OEM version is the smallest fully
functional, stand-alone infrared

temperature sensor for fixed
installation on the market today. Designed for a wide range of
applications, 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 180 °C
(356 °F) without cooling. Cooling accessories not only add
installation costs, they can leak and contaminate products, or
condensation produced by cooling can obscure the sensor’s
field of view and interfere with measurement accuracy.

long, the single piece

For use with standard industrial outputs, the

MI3 sensor comes with the separate

communication box MI3COMM,

which provides all the functionality

of the proven MI series sensors
with numerous exciting new

features.

The multi-channel MI3MCOMM
communication box for multiple
sensing head applications with USB
interface as standard and a wide
range of network communication
interfaces is available in a convenient

DIN-rail mountable package.

4 sensing heads can be directly
connected to the MI3MCOMM box.

Multi-channel sensor interface box
for connecting up to 8 individually
addressable heads to the

communication box.

Highlights: MI3 Series

■

Lowest installation costs per
measurement point due to multiple
sensing head system design

■

Self diagnostic features: break of a head

wire, head internal temperature

■

Plug & Play exchangeability for sensing

heads (no heads parameter anymore;
Raytek patent)

■

Robust EMI immunity due to digital
head-to-box communication

■

No cable bending/moving effects, allowing
continuous reliable measurement in
moving installations (robotic arms, linear
drives, chains, etc.)

■

Optional network communication
interfaces: RS485, Profibus , Modbus ®,
Ethernet, Profinet

■

64 MB data logger for communication
boxes with Ethernet

■

Optional 4 analog outputs with galvanic
isolation

■

OEM version allows direct digital
communication with the host machine
controller without the need for an
additional communication box

The OEMMI3 version of all MI3 sensor models
allows direct digital connection to the host
machine controller. No communication
box is required. This is ideal for high
volume OEM applications requiring
MI3 performance with the best possible
value and minimum installation costs.

MI3100
High Temperature Sensor

The MI3100 high temperature sensing head represents a
further extension of performance and innovation in continuous
noncontact temperature monitoring for specific OEM applications
and high temperature manufacturing processes. The short
wavelength sensor delivers more accurate measurements vs.
long-wavelength units in case of emissivity changes (for example:
metals, ceramics).

The MI3100 is a rugged, IP65 stainless steel sensing
head to handle many applications in a wide
temperature range.

or by combustible dust. Explosions
can cause loss of life and serious
injuries, as well as significant damage.
If you are working in this hazardous
environment and need instruments
with special certification, Raytek MI3
ATEX/IECEx certified sensors can
be used safely to monitor the right
temperature of your process. All standard
MI3 and MI3100 heads can be ordered with
optional ATEX/IECEx certification. Raytek
