• Contactless temperature meas- urement at high ambient tem- • Robust and tight stainless steel • Measuring head is pluggable tactless temperature measurement at high ambient temperatures. This technology is very favourable near the measured object. No cool- In the system technology no open- ings and cross-flow blowers are required. This results in a signifi- cant cost reduction. The contact-free measuring princi- ple makes especially sense if the measured object either has a low heat conductivity or is in movement This results in a variety of applica- continuous furnaces for lacquer dry- ing, textile and paper drying etc. The quite small design of the measuring head permits the mount- ing even under extremely narrow space conditions A silicon window tightly seals the optical system against the environ- The connection cable of the sensor is also suitable for high ambient against damages by means of a corrugated pipe.
