Analog pyrometer CellaCast PA 80

RS485USB0-10 V

Product overview
The CellaCast PA 80 is an infrared pyrometer designed for non-contact temperature measurement of molten metals in casting channels, transfer ladles and during metal transfer operations. It is suited to continuous casting and high-temperature metallurgical processes.

Key features

• Measuring range: 750 to 2400 °C
• Two-colour measurement for interference-free readings in presence of dust and vapour
• ATD function to filter measurements of slag-free and oxide-free metal surfaces
• Wear-free, maintenance-free sensor system for harsh metallurgical environments
• High-resolution optics for reliable long-distance measurement
• Sighting via through-the-lens, laser pilot light or optional video camera
