General Description
The MD9100 is a
remote “All-in-One” Hot Metal Detector that combines the features of
various models of Hot Metal Detectors into one unit. The MD9100 utilizes a modular electronic
controller, flexible armored fiber optic leads and interchangeable
remote lenses.
The MD9100 detector
provides one electronic controller that can be standardized on
throughout the mill. Now there is no need to stock a detector for each
different trip level. Thus costly inventory of ordinary detectors can be
replaced with the single MD9100.
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 fiber optic leads, 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 and 1000°C can be mounted close to
the hot product. Various robust lens mounts are available including air
purged, air purged & air cooled, and air purged & water cooled.
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. Also
available is a high temperature Quartz Rod lens specifically for
mounting in exceptionally high ambient adjacent to furnaces, hot slabs
or billets. Withstands 1000°C radiant heat and provided in a robust lens
shroud with protective nozzle and air purge facility.
To accommodate
variation in product temperature and background Infrared radiation. Six specific
Infrared (I.R.) thresholds, from 300°C to 550°C, are selectable by an internal DIP
switch in 50°C steps. Further adjustment to the trip level down to 270°C
and up to 750°C can be accomplished via a threshold sensitivity
adjuster.
The MD9100 can be
operate from either 110VAC-50/60 Hz or 24VDC power input. Standard
output includes a relay with a 8A/250VAC SPNO volt free contact plus an
additional switch selectable PNP & NPN transistor output. A
supplementary 0-6VDC, non-linear, analog output that allows the user
to align the detector to a low energy target (i.e. a flashlight) that
would normally be insufficient to switch the detector. Also a remote
self check feature that is remotely initiated. When activated the
detector will switch and its performance checked.
We can provide
direct replacements for Hubbell / Euclid,
Type 9207 High Speed
Detectors,
Type 9800 Hot
Metal Detector and Type 9900 Hot Metal Detector,
Type 9700 Long Range
Proximity Switches, Type 9701 Pulse Type Long Range Proximity
Switches, Photo
Electric Switches and Optical Position Detectors.
