Article description

The CellaTemp® PKL 38 has an integrated LED pilot light. Especially for small measuring objects from Ø1.2 mm, the pilot light is an indispensable aid for aligning the infrared thermometer with the hot zone and setting it to the correct focal distance. The LED pilot light is illuminated continuously and offers a high degree of operational safety due to the permanent control option. 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 500 to 2,500 °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
  • LED pilot light is permanently on as well as parallax-free and safe

Pyrometer CellaTemp PKL 38

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.
