Precise Temperature Measurement of the Casting Stream from 700
°C to 1800 °C
The casting stream measurement system is based on digital ratio
pyrometers of the PYROSPOT series, combined with a display and
evaluation unit and parameterizable software. It is specifi cally
designed for industrial purpose in foundries for temperature
measurements of the casting stream.
Depending on application conditions you can chose between a
pyrometer with fi ber optic cable and special optics (PYROCAST) and
a pyrometer with integrated video camera and a special rectangular
measurement fi eld (PYROCAST PRO).
The temperature linear output signal of 0/4 to 20 mA is
available. The measurement temperature can be viewed on a large LED
display.
The special optics guarantees an exact temperature measurement
even when the measurement fi eld is not fi lled completely or when
the casting stream is moving.
Easy access via Software at any timeThe special software allows
the adjustment of different parameters to the respective casting
process. For every casting process a relevant average value over
the temperature is output and occuring troubles, for example at the
sprue, are faded out. The controller is programmed via Ethernet
interface and it can be integrated into the remote maintenance. It
is possible to access to the device in a running process to
optimize settings and to solve a problem. The software is
multilingual. You can switch between English, German and Spanish.
Further languages are available on request.

The advantages of the PYROCAST Pyrometer System A reliable
temperature measurement even at very low or fl uctuating emissivity
The special optics compensate the movement of the casting stream
and need only a little fi lling of the measurement fi eld To avoid
dust effects the optics can be protected with an air purge unit and
a sighting tube The precise aiming og the pyrometer to the
measurement object is made with the integrated laser aiming light
or a video image in real-time
Webserver
The system is controlled via the integrated
web server. Even in a running process it is
possible to optimize settings in the web
browser that contains the temperature profile
and the value table.
The web server allows the adjustment of
different parameters to the respective casting
process. Besides the detection of a relevant
average value via whom signal variations
(e.g. at the sprue) can be faded out, the
beginning and the end of a casting process
can be detected automatically.
