Pyrometer CellaCast PA 80

Article description

The CellaCast PA 80 was specially developed for measuring the temperature of liquid metals in the casting channels of blast furnaces and cupola furnaces. Furthermore, the pyrometer is used when transferring the metal from the melting or holding furnace into the transport ladle or casting ladle.

Special features:
  • Measuring range 750 to 2
  • 400 °C -- wear-free and maintenance-free measuring system for temperature measurement in melting and holding furnaces as well as cupolas and blast furnaces -- ATD function for filtering the temperature of the slag-free and oxide-free metal surface -- two-colour measuring method for interference-free measurement in the presence of dust and vapour -- high-resolution lens for reliable measurement even from a great distance -- through-the-lens sighting or laser pilot light or video camera for correct alignment and monitoring of the measuring field

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 at the pyrometer and the ambient temperature (required for some instrument types).
The value displayed by the pyrometer is calculated from the true object temperature, the emissivity of the measurement object, the emissivity set on the pyrometer and the ambient temperature (required for some instrument types).
