Model MD85100 Digital Hot
Metal Detector (HMD) Technical Info |
|
|
|
|
The following is
specifications and dimensional information on the housing for the Moduloc
Control Systems Model MD85100 of Self Contained “All-in-One”
Digital Hot Metal Detector.
|
|
Additional Technical Information
To accommodate variation in bar temperature and background IR, various
precise threshold are programmable via covered switches from
250°C
to 1,000°C ( 518°F to 1832°F) to ensure reliable switching with reference to both the
displayed background and product IR signal. Furthermore, response time
is programmable from 1ms to 250ms to accommodate black spots on the bar.
The
MD85100 incorporates a remote self-check facility remotely energized by
closed contacts that lights up an internal IR LED to switch the detector
and verify its' outputs operate correctly.
The
MD85100 will operate from either 80-240 VAC or 24VDC power input.
Standard outputs include a cradle relay, a fast reed relay and both NPN/PNP
transistor outputs. |

The model MD85100 is
shipped as standard with 0.5°
x 25° FOV lens. Other lenses, as listed in the table below, may be
chosen to accommodate the monitoring of both large and small product at
close proximity or substantial distance. Even product dramatically
deviating about the center of Field of View can be monitored with a slit
Field of View lens arrangement.
