The scanning optical system, in association with state-of-the-art infrared photocell technology, is the optimal solution for accurate, fast and reliable detection of product, whatever its size and its temperature. The Scanning Hot Metal Detector Rota-Sonde DC works under adverse conditions such as water, steam, dust or scale. It is particularly well adapted to applications where the change of the process results in a significant variation of the temperature of the product or a variation of its emissivity factor.
The Rota-Sonde DC4500 is a scanning sensor, which is sensitive to the infrared radiation emitted by hot products.
It is a self-contained detector including:
An optoelectronic case with heavy duty connector.
A protecting hood with air purging.
A cooling plate with an adjustable mounting stand.
Thanks to its design and particularly its cast aluminium housing, the Rota-Sonde DC4500 is specially adapted for the harsh environment of the Steel Industry (shocks, vibrations, heat, vapour and dust).
High detection accuracy thanks to the narrow lateral field: independent of product temperature, size or position.
Reliable detection even in the presence of steam or dust thanks to the small analysing beam.
Easy alignment of the sensor with integrated laser line (model –LL) or laser pointer (model –LP).
Easy setup with integrated LED bar-graphs: signal amplitude and detection thresholds.
Extensive diagnostic features including display of alarm and low detection margin signals.
High sensitivity: 180 °C / 360 °F.
2 sensitivity ranges with on line selection.
Shutter with 2 fixed apertures: 2 mm for usual applications and 0.7 mm for high temperature applications.
Easy maintenance: very quick access to window glass, rapid exchange of the sensor.
Direct replacement of DELTA models Rota-Sonde DC3000 and DC4000.
Remote setting and diagnostic with optional junction box CR4500DC, when access to sensor is not easy.
Choice between relay output (DC45x0-xx) and static relay output (DC45x6-xx)
