Pyrometer CellaTemp PK 51

Article description

The CellaTemp® PK 51 was developed especially for temperature measurements in flame heated furnaces. Thanks to the selective spectral range of 3.9 µm, water vapour and CO2 existing in the pyrometer´s field of vision have no effect on the measuring results, even when measuring from large distances. This allows precise measurements through flames and combustion gases. The new generation of the CellaTemp® PK pyrometer series is equipped with a smart function, the vitality indicator.
This is a self-monitoring, analysis and reporting technology (SMART), i.e. a function for self-monitoring, analysis and status reporting. The vitality monitor continuously records all relevant operating data. As part of preventive maintenance, this enables the pyrometer to autonomously signal the optimum time for a service check and calibration, depending on the operating conditions.

Special features:
  • Measuring range 400 to 1,400 °C
  • switching output universally configurable
  • high optical resolution due to precision lenses
  • IO-Link interface
  • all parameters can be set via pushbutton on the sensor or via interface from the plant control system
  • 2 x switching outputs PNP open collector
  • very simple mounting via M30 central thread
  • large and bright LED display

Pyrometer CellaTemp PK 51

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.
