Digital 2-color pyrometer with fibre optic for non-contact temperature measurement of a cast iron pouring stream. Temperature ranges between 750 and 2500 °C.
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 has 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 pyrometers are equipped with a lens contamination monitoring system. If the signal strength is too low caused by contamination of the lens or a sighting window, a signal output switches an alarm transmitter.
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 controlled very accurately to achieve the high quality requirements of casted parts. The measured values can be stored and displayed via analog and digital output.
