D-VTA 200


The D-VTA 200 video and ­thermography system is a modular system specially developed for use in the cement industry, to monitor the clinker manufacturing process.

Intelligent sensors allow contactless, optical and thermal online analysis of processes in the sinter zone in rotary kilns and in clinker coolers.
