Foundries: Measurement of the Iron Stream temperature

forging application

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.

The whole system consist

- Digital ratio pyrometer with 10 mtr long fibre optic cable for temperature range from 800°C…2500°C.Two Color technology

overcomes the problems of incompletely filled measuring spots, supplied with accessories like air purge unit which minimizes the effect of dust and smoke on the proper working of the lens.

- Fibre optic Cable - Special Fibre optic cable and optical head can withstand high ambient temperature upto 250°C whereas pyrometer end(0°C…70°C).

Fibre optic system allows installing the pyrometer securely inside the control box and away from site which has high ambient conditions.

- Junction box with LED display

- Connection Cables of varying lengths available.

- Software Infrasoft: The software is useful for adjustments of parameters and parametrization.
