D-VTA 200


The Video-based D-VTA 200 Thermography System is a modular system for monitoring industrial high temperature processes.

Intelligent sensors allow contactless, optical and thermal online analysis of processes in the combustion chamber.


  • Applications
  • Technical Data
  • Downloads
  • Detection of the Temperature Distribution in side combustion chambers; analysis of unbalanced combustion processes
  • Burning analysis and slag monitoring in power plants
  • Visualization of flame post combustion chambers and flame front monitoring in waste incineration plants
  • Monitoring ore calcination and hazardous waste disposal in the chemical industry
  • Annealing and pusher furnace monitoring in the steel industry
  • Scale formation and melting charge control in the glass industry.

The Thermography Analysis System additionally offers:


  • Temperature determination of each visible image point of the video sensor
  • Thermal analysis of the local temperature distribution
  • Temperature definition within freely definable measuring window and lines (ROI = Region of Interest / LOI = Line Of Interest).
  • Analysis of thermal samples to identify anomalies in the combustion process
