Mirion Technologies M704 User Manual
FEATURES
Camera and Pyrometer All-in-one•
The pyrometer shares the same optical path as the camera
video signal and provides an accuracy of ±1%. You can see
exactly where the temperature is being measured on a small
locator square displayed on the control room monitor. The
temperature value is shown on the M704 front panel LED
display and can be exported as an isolated analog 4-20mA
signal.
Colorization•
The M704 colorizes the incoming infrared black and white
video signal. Hot items appear as yellow or white while
cooler items appear as darker reds.
Contrast Expansion•
Independent operator control of the black and white
levels allow the maximum contrast range to be achieved.
Increased contrast expansion provides a better picture.

Viewing Pyrometer
Part of the IST-Quadtek M300 Bedbug
Range of Smelt Bed Imaging Systems
Pyrometers are great at measuring how hot your
process is, but you never know exactly where they are
pointing. The IST-Quadtek M704 Viewing Pyrometer
takes the guesswork out of it by showing you on the
monitor. The pyrometer temperature data is multiplexed
with the video signal and sent to the M704 unit. It
separates them and displays the video on a monitor
with a locator square on the screen which marks the
specic area that the pyrometer is measuring.
Under ideal conditions a camera system gives operators
an excellent view of the combustion process, but most
industrial processes are prone to conditions that make
it hard to see clearly. The M704 gives operators an
added advantage by overcoming these difcult imaging
problems by colorizing the image and providing contrast
expansion and custom shading control.
Shading Correction•
A ner degree of control is possible using the four shading
controls. This allows contrast to be adjusted over a portion
of the screen. Extremely useful when difcult imaging
conditions only affect part of the image.
Video Alarm Loss•
High output audible alarm sounds if video signal is lost.
Licensed Camera Initiation•
Provides automatic initialization (interlock) of special versions
of M300 Bedbug cameras using licensed camera cores.
Multiple Video Output Formats•
A choice of four types of video output to allow early
connection to most commercial monitors or large screen
displays.

SPECIFICATIONS AND PERFORMANCE
Figure A shows a typical video signal. The distance
between the white level (at the top) and the black level
(at the bottom) is the total range of contrast available.
Figure B shows that by dropping the black level, the
distance between the white and black levels gets bigger,
increasing the contrast range. By lowering the black
level, the darker objects get darker without changing
the white ones. Likewise is true when the white level is
raised, the white objects get whiter without changing the
dark ones.

Black Level
Shading correction is accomplished by applying
sawtooth and parabolic correction signals to the video
signal.
For example, when the video signal is combined with
the horizontal sawtooth signal, one side or the other of
the picture gets lighter while the other side darkens. The
horizontal parabolic signal lightens or darkens only the
edges of the picture. The vertical controls do the same
thing as the horizontal, only from top to bottom.
