Pyrometer CellaCrystal PX 45

Article description

The CellaCrystal PX 45 has been developed for optical temperature measurement in high-temperature furnaces for crystal growing up to 3200 °C. The pyrometer, which is based on the two-colour measurement principle, is characterised by a very large measuring range with a consistently high resolution of < 0.1 K over the entire measuring range. A special signal processing ensures very high measuring accuracy. Therefore, the device fulfils the high requirements for long-term stability necessary for the production process. With the help of the through-the-lens sighting or the video camera, the pyrometer can be precisely aligned to the measuring point.

Special features:
  • Measuring range 900 to 3200 °C
  • particularly suitable for the production of crystals at very high process temperatures
  • Hybrid signal evaluation for high metrological resolution
  • High long-term stability due to minimal self-heating
  • Focusable optics for precise adjustment of the measuring distance
  • Narrow field of view enables measurement through small furnace openings
  • Standard features: analogue output and USB/RS 485 interface

Pyrometer CellaCrystal PX 45

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.
