Introduction
2.1
Appropriate use
The pyrometers ISR 12-LO/GS is a special foundry system for the measurement of the pouring
stream in foundries. This system is useful in automatic or semi automatic pouring machines and
displays the temperature after each single pouring process.
A ratio pyrometer is required for this application because
•
molten metal has a very low and fluctuating emissivity
•
the position of the pouring stream is moving so that the measuring spot of the
pyrometer is only partially filled
The pyrometer is equipped with a special pouring stream mode which calculates one average
temperature value for each single casting process. Temperature values in the beginning and the
end of the casting process can be eliminated which can affect the correct measurement. The
shape of the spot size of the optics is a line which guarantees that even a moving pouring
stream is always within the spot.
The pouring stream temperature of each single casting process and with that of each single
casted part can be recorded automatically with the ISR 12-LO/GS. The temperature value of each
finished casting process is displayed on the pyrometer and available as analog and digital
output. With that the casting can be con-trolled very accurately to achieve the high-quality
requirements of casted parts.
The measured values can be stored and displayed via analog and digital output.
Note:
If the pyrometer should be used in other applications, the pouring stream
mode can be switched off to use the pyrometer in standard 2-color or 1-color mode to
use like a conventional pyrometer. In this case the descriptions printed in grey color
have to be noticed.
