Optical pyrometer CellaCast PA 83

LEDRS485USB

Product overview
The CellaCast PA 83 pyrometer is designed to measure the temperature of molten metals on automatic casting machines (plug and ladle casting). Its rectangular measuring field provides reliable readings even when the pouring stream shifts within the field.

Key features

• Measuring range: 650 to 1,700 °C (also available in other segments up to 2,400 °C)
• Wear-free, maintenance-free optical measuring system for pouring-stream temperature measurement
• Rectangular measuring field for reliable measurement with fluctuating stream position
• ATD function for automatic recording and monitoring of temperature per casting
• Two-colour measuring method for interference-free measurement in presence of dust and vapour
• Through-the-lens sighting or video camera option for alignment and monitoring
• Large, bright LED display
