Presentation and operating principle
The Rota-Sonde DC2038 is a Hot Metal Detector for material at temperatures over 500 °C (932 °F). Thanks to its optical fiber it is able to detect products which are not in its direct field of view (due to physical obstructions, limited space, etc.), even in areas of high ambient temperature.
Because of its rugged design it withstands the severe environmental conditions of the steel industry.
The Rota-Sonde DC2038 is a self-contained sensor, complete with:
The infrared radiation emitted by the hot product is collected by the optical fiber cable and transmitted to the
photosensitive element. The photocell signal is processed by the electronic circuit which outputs the detection signal.
The sensor field of view is determined by the lens assembly attached to the optical fiber cable.
Detection temperature for different % of the field of view filled by hot product for 2 m, 3 m and 5 m fiber length. Sensor adjusted at max sensitivity (7).
