[ DIAS PYROSPOT 11 Series ]

The DIAS PYROSPOT 11 Series are digital infrared pyrometers with fibre optics and optical head enable that non-contact measurement for industrial applications from 150 °C to 3000 °C. The pyrometer’s parameters can be set directly on the device via keyboard and display or via the RS485 interface with the configuration and monitoring PYROSOFT Spot software. Applications include steel and metal industries, kiln engineering, hardening, welding, brazing and ceramics industries.

The digital ratio pyrometers PYROSPOT DSRF 11N utilize the 2-colour system which has the advantage of measurement widely independent from the emissivity in range from 700 °C to 3000 °C.

  • Measurement range from 150°C to 3000°C
  • Fibre optics and optical head for up to 250 °C ambient temperature
  • Short response time from 2ms
  • Measurement uncertainty from 0.5% (DGF 11N, DSR 11N, DSRF 11N) or 0.5% + 2°C (DGEF 11N)
  • 4 to 20mA (0 to 20mA) adjustable output
  • Display and keyboard, to adjust the ratio correction (DSR 10N) or the soot factor (DSR 10NF)
  • Keys and display to show the temperature and for adjusting the parameters
  • Various optics, with spot sizes from 0.7mm
  • Laser aiming light for sighting
  • Optional colour camera with video output
  • RS485-interface for pyrometer configuration and monitoring with PYROSOFT Spot software
  • Cast housing, 110 mm × 80 mm × 40 mm, degree of protection IP 65
