Article description



The CellaTemp® PX 41 is a digital two-colour pyrometer with a fibre optic cable for measuring temperatures between 700 and 3,000 °C. The two-colour pyrometer is equipped with a separate optical measuring head and a fibre optic cable. The fibre optic cable and measuring head are insensitive to interference from electromagnetic radiation and can be used in ambient temperatures up to 250 °C without cooling. The variant with separate optical measuring head has advantages especially in confined spaces.

Special features:
  • Measuring range 700 to 3,000 °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
  • measuring head and fibre optic cable heat resistant up to 250 °C

Pyrometer CellaTemp PX 41

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.
