Article description



The CellaFurnace PA 46 has been specifically developed for non-contact temperature measurement in vacuum, inert gas, and high-temperature furnaces.

Its innovative hybrid signal processing technology provides a consistently high temperature resolution of 0.1 K across the entire measuring range from 900 to 3200 °C. Combined with the use of a double diode in a sandwich construction without moving components, the pyrometer achieves outstanding measurement accuracy, repeatability, and long-term stability.

The proven two-color measurement method ensures reliable temperature measurement even under critical process conditions, such as contaminated observation windows.

Thanks to its focusable precision optics and extremely small spot size, the pyrometer is ideally suited for measurements through small viewing ports and furnace openings. For precise targeting of the measurement spot, the instrument can be equipped with either an optical through-the-lens sight or an integrated video camera.

As a result, the CellaFurnace PA 46 meets the demanding measurement and optical requirements of advanced high-temperature processes in the graphite, carbon, battery, semiconductor, and advanced materials industries.

Special features:
  • Wide continuous measuring range from 900 to 3200 °C
  • Designed for temperature measurement in vacuum, inert gas, and high-temperature furnaces with small sighting window
  • Hybrid signal processing for high temperature resolution
  • Excellent long-term stability
  • Focusable precision lens for accurate alignment and exact adjustment of the measuring distance
  • Standard features: analog output and USB/RS-485 interface
