The Onyx™-MC is a multi-channel, non-contact optical fiber temperature pyrometer. It measures infrared energy being emitted from an object and converts this into usable temperature data (degrees °F or °C) for process control in industrial manufacturing. The Onyx-MC can be configured in a variety of measurement wavelengths based on target materials, required process temperatures, and working distances spanning from 3.9 in (100 mm) to 118.1 in (3000 mm). Use up to four independent measurement channels, with separate optical sensors connected by fiber optic cables.


  • Provides precise temperature measurement, even under harsh operating conditions
  • Integrates with PLC/PAC for closed-loop control of critical thermal processes
  • Improves product quality by precisely controlling temperatures that affect material properties
  • Increases product throughput by increasing heat ramping efficiency and dwell times
  • Decreases energy costs by controlling energy use (fuel or electricity)


  • Available temperature ranges are: 1112°F (600°C) to 2912°F (1600°C)
  • Configurable wavelengths and temperature range, based on application and material requirements
  • Small, remote optical sensor and fiber optic cables for easier integration into enclosed spaces
  • Precise measurement for moving, rotating, or inaccessible work pieces, or when direct physical contact would damage the work product
  • Non-contact device, providing years of service without interruption and requiring minimal maintenance or re-calibration
