Article description

The CellaTemp® PX 31 is a digital pyrometer with a fibre optic cable for measuring temperatures between 550 and 2,500 °C. The 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 600 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
