Pyrometer CellaTemp PX 28

Article description

Thanks to its high-intensity lens, a special sensor and patented signal evaluation, the CellaTemp® PX 28 is able to deliver precise measured values even with extremely low infrared radiation. This pyrometer is used to measure metals at very low temperatures.

Special features:
  • Measuring range 75 to 650 °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

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.
