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.

More MI3 features are available with the
USB or optional RS485 communications
and the DataTemp
including remote control and monitoring of
all sensor variables, an 8-position “recipe”
table that can be easily interfaced to an
external control system, and even external
inputs for analog emissivity adjustment or
reflected energy compensation.

Plot temperature values of multiple sensors
simultaneously. High and low alarms are
shown, making it easy to identify an out-of­range condition.

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.
