Article description

The CellaTemp® PX 20 is a digital pyrometer for measuring temperatures from 210 to 2,500 °C. Due to the very large measuring span, it can be used very universally for a variety of applications. A through-the-lens sighting or a laser pilot light is available for easy and precise sighting of the measuring object. Parameters such as emissivity, measuring range or smoothing constants can be set with the rear buttons. The changed parameters are shown on the LED display. In normal operation, the current measuring temperature is displayed.

Special features:
  • Measuring range 210 to 2,500 °C
  • modern IO-Link interface
  • focusable interchangeable lenses for exact adjustment of the measuring distance
  • broadband anti-reflective precision lenses
  • LED display can be read from a great distance
  • all parameters and functions adjustable via keyboard
  • test current output for the diagnostic function
  • 1 analogue output and 2 switching outputs
  • source freely configurable
  • ATD function for automatic temperature detection

Pyrometer CellaTemp PX 20

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.
