The Rota-Sonde DC2000 is a scanning sensor, which is sensitive to the infrared radiation emitted by hot products.
It is a self-contained detector including :
Because of its design and particularly its cast aluminium case, the Rota-Sonde DC2000 is specially adapted for the harsh environment of the Steel Industry (vibrations, heat, vapour and dust).
The detection field is scanned by a rotating polygonal mirror which reflects the infrared radiation from the product to the photocell
Because of the exclusive optical scanning principle, the Rota-Sonde DC2000 offers the following advantages :
All these features give accurate and reliable detection, whatever the dimensions and the temperature of the product, or its distance and its position in the scanned field.
The Rota-Sonde DC2000 is fitted with a special photosensitive cell, the best compound for detection of metal, even at a temperature as low as 400 °C (750 °F).
The Rota-Sonde DC2000 is enclosed in a sealed cast aluminium case.
A hood for protecting the window glass is fitted with an air-jet facility to blow a vertical air curtain in front of this glass. The protective hood can be hinged down to clean the window.
The case is mounted on a cooling plate including a stainless steel pipe and fixed to a mounting stand, adjustable in two axes. The water and air purging connections are on the support plate. In this way it is possible to remove the sensor without first disconnecting the water and air supplies and without need of optical re-alignment.
