Article description



The CellaCrystal PX 45 has been developed for optical temperature measurement in high-temperature furnaces up to 3200 °C for crystal growing. The pyrometer, which is based on the quotient measuring method, is characterized by a very large measuring range with a consistently high resolution of < 0.1 K over the entire measuring range. Special signal processing ensures very high measuring accuracy. The device therefore meets the high requirements for long-term stability necessary for the production process. The pyrometer can be precisely aligned with the measuring point using the through-the-lens sight or the video camera.

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: Analog output and IO-Link 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 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).
