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 infra-red energy radiating from the hot
product. Impervious to water or steam it is built to withstand the
harshest of environments. The lens incorporates filtering that removes
the visible spectrum to minimize sensitivity to extraneous light. For
general tracking applications spot lenses are commonly the choice. For
applications where the bar bounces or there is strip to be detected, and
for precise detection is essential then the 1° x 25° lens should be
utilized.
This MD85100 Hot Metal Detector is especially suitable where
ambient temperatures are subject to large changes. In standard housing
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.
