Typical Applications
- Detection
of Hot Metal or Hot Product in a Rod Mill, Bar Mall, Rolling Mill,
Plate Mill, Roughing Mill, Hot Strip Mill
or other Steel Mill and Industrial Applications.
The MD9207 Remote High Speed Hot Product Detector is
an electronic optical sensor built to meet the higher speed detection
requirements within the modern steel mill. Armored fiber optic leads
allow the lens to be installed close to the process line in high
ambient, while allowing the controller to be mounted in an accessible
area. The MD9207 provides a 0.5 msec “pulsed” N.O, PNP transistor output
and a “latched” N.O. PNP transistor output, initiated by the passing of
a hot leading edge. In addition two independent latched reed relay
outputs are also provided. The detector’s response time is virtually
independent of the target temperature. In addition, background radiation
is filtered out by processing the IR signal present in the field of view
of the lens through both a slow and fast amplifier channel. A
traditional threshold adjustment is not required.
A wide variety of remote lenses are available. Impervious to water or
steam and built to withstand the harshest environments. Used in
conjunction with flexible armored optic lead, these lenses provide a
high level of optical accuracy by allowing the selection of the ideal
lens arrangement for the installation. Robust lenses with temperature
ratings of 180°C, 400°C can be mounted close to the hot product. All
remote lenses incorporate filters to minimize sensitivity to extraneous
light. For general tracking, spot lenses are commonly used. Where high
accuracy is required or the product deviates about the center line (i.e.
Rod Mill) a ½° x 25° precision slit rectangular lens should be utilized.
This slit rectangular lens is also highly suited to Strip Mills. Various
robust lens mounts are available including air purged, air purged & air
cooled, and air purged & water cooled.
The MD9207 is provided with a remote self check feature that is remotely
initiated. When activated the detector will switch and its performance
checked.
