Pyrometer CellaCombustion PX 47

Article description

The CellaCombustion PX 47 is a special pyrometer for non-contact temperature measurement of sooty flames in coal-fired power stations and incineration plants. The measurement and signal processing, both based on the two-colour method, detect the heat radiation of the soot emitting particles of the flame in the near infrared range at two wavelengths. In order to correct the influence of the wavelength-dependent radiation properties of the soot particles and the optical density of flames, a special algorithm is used during the temperature determination. The flame temperature can be used to control the burnout in the furnace operation in order to reduce pollutant emissions and minimize slagging of the combustion chamber walls.

Special features:
  • Measuring range 700 to 1,700 °C
  • modern IO-Link interface
  • focusable lenses for exact adjustment of the measuring distance
  • broadband anti-reflective precision lens
  • LED display can be read from a great distance
  • test current output for the diagnostic function
  • 1 analogue output and 2 switching outputs
  • source freely configurable

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.
