Foundries: Measurement of the Iron Stream temperature

The temperature measurement of pouring iron stream is crucial for achieving high quality cast products.

A two color pyrometer with Fibre optics AST 450C FO/PL is recommended for this application due to conditions like very

low and fluctuating emissivity's along with the continuous moving and changing position of the of iron stream. The pyrometer is

specially designed for the reliable temperature measurement of Iron Stream in Cast houses.

Two color (Ratio) technique helps to overcome the inaccuracies due to atmospheric disturbances like water vapor, dust and contamination on lens etc.

  AST 450C FO/PL

Key Features

• Rugged mono fiber optics
• Wide temperature range
• Laser targeting light
• USB Output
• Small Spot sizes
• Analog output 0…20mA or 4…20mA or 0-10 V
• Digital interference RS 232 or RS 485
• Fiber optics and optical head withstand up to 250°C

Pyrometer has laser targeting light which can be turned ON/OFF which helps the user for precision targeting.

The digital output of the pyrometer is connected to temperature controller with parameterizer so that all the parameters of the pyrometer can be set

without the help of PC or laptop. Auxiliary output of 24VDC from P120 is used to power the pyrometer. Hence the system is standalone and user friendly.
