The Raytek

MI3 is a powerful two-piece infrared temperature
measurement system with miniature sensing head and separate
communications electronics. The sensor is small enough to be installed
just about anywhere, yet it outperforms much larger systems. Available
in either a rugged cast metal electronics enclosure, an innovative multi­channel DIN mountable enclosure, or low cost OEM configurations, the
MI3 offers a host of advanced signal processing features you won’t
normally find in sensors costing much more.

The MI3 features a variety of sensing head options. High temperature
sensors with a measurement range of 250°C to 1800°C (482°F to
3272

°F), fast response (10 mSec), 1.0, 1.6 µm spectral response
sensors and laser sighted 100:1 optics provide an impressive solution
for your process needs. The rugged stainless steel sensing head ensures
reliable long term performance in the harshest industrial environments.
Although the MI3 sensor is small in size, it has all the performance you
need for the most demanding applications.

Standard features include adjustable Emissivity, Peak Hold, Valley Hold,
and Averaging functions. All sensor parameters are easily adjustable
on the built-in user interface keypad, or remotely with the Windows
7 compatible DataTemp software via the built-in USB interface.
Advanced features further extend the power of the MI3 and include
user configurable alarm output, digital “recipe” table inputs that can be
easily interfaced to an external control system, an external reset input for
signal processing, and external inputs for analog emissivity adjustment
or reflected energy compensation. Optional RS485, Modbus

®

, Profibus or
Analog output network interfaces simplify intergration with a factory or
machine control system.

The MI3’s miniature size and low cost per measurement point make
it ideal for installation at multiple points in your process. The MI3 is
accurate, rugged, affordable, easy-to-install and operate. With the MI3,
precision infrared temperature measurement is now an economical
alternative.
