Pyrometer CellaCast PA 83

Article description

The CellaCast PA 83 was specially developed for measuring the temperature of liquid metals on automatic casting machines for plug and ladle casting. When measuring on an automatic casting machine, the position of the pouring stream can change depending on the outlet or the tilt angle of the ladle. The special feature of the CellaCast PA 83 is the rectangular measuring field. As long as the pouring stream remains within the measuring field, a reliable measured value is determined.

Special features:
  • Measuring range 650 to 1,700 °C
  • wear-free and maintenance-free measuring system for temperature measurement of the pouring stream on automatic casting machines
  • lens with rectangular measuring field for reliable measurement even with fluctuating position of the pouring stream
  • ATD function for automatic recording and monitoring of the temperature for each casting
  • two-colour measuring method for interference-free measurement in dust and vapour
  • through-the-lens sighting or video camera for correct alignment and monitoring of the measuring field
  • very large and bright LED display

Pyrometer CellaCast PA 83

Emissivity calculator

The correct emissivity to be set on the pyrometer is calculated from the measured value displayed on the pyrometer, the true object temperature, the emissivity preset on the pyrometer and the ambient temperature (necessary for some types).
From the true object temperature, the emissivity of the measurement object, the emissivity set on the pyrometer and the ambient temperature (required for types), the measured value calculated by the pyrometer is displayed.
