Model MD85100 Digital Hot Metal Detector
The MD85100 is a fully digital “All-in-One” Hot metal Detector uniquely incorporating a bar display showing the % IR input signal relative to the pre-set threshold as well as programmable thresholds and response times via simple programming switch action. This and the universal connection format means it provides the user with one universal Detector that can be used throughout the mill. The MD85100 is the economical choice. Now there is no
need to stock various Detectors for each location. Costly multiple inventory can be replaced by one Detector.
The MD85100 Hot Metal Detector is a robust sensor activated by the infrared radiating from the hot product. Impervious to water or steam, it is built to withstand the harshest of environments. The product is detected via a highly stable InGaAs Photodiode to ensure detection regardless of heavy water and steam and incorporates filtering that removes the visible spectrum to minimize sensitivity to extraneous light. The precise 1ºx25º lens ensures accurate detection of strip and accommodates bar bounce. For general tracking or mounting the HMD at a long distance from the line various spot lenses are available.
This Detector is especially suitable where ambient temperatures are subject to large changes. In standard format, a large air cooled chamber vents via deflector in front of the lens to allow the use of non-instrument air and provides air purging. Alternatively, an optional sealed loop water coolant radiator accommodates tap pressure and a separate air purge inlet may be provided.
