Industry Hot Metal Detection Sensor

Industry Hot Metal Detection Equipment

General Description

The MSE-HMD85 Hot Metal Detector is a robust sensor activated by the infra-red 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 0.5° x 25° lens ensures accurate detection of strip and accommodates bar bounce.

This MSE-HMD85 Hot Metal 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.

Air & Water Specifications

Air Pressure: 1 cu ft./min at 5 PSI for normal conditions

                    5 cu ft./min at 15 PSI for severe conditions

Water Pressure: 5 to 10 PSI, 40 PSI Maximum

Water Volume: Regulate between 0.2 - 0.3 liters/min.

Water Temp.:

For Ambient Temperature up to 70°C use ambient water below 20°C

For Ambient Temperature up to 80°C use water chilled up to 10°C

Additional Information

To accommodate variation in bar temperature and background IR, various precise threshold are programmable via covered switches from 270°C to ensure reliable switching with reference to both the displayed background and product IR signal. Furthermore, response time is programmable from 1 ms to 250ms to accommodate black spots on the hot material.

The MSE-HMD85 Hot Metal Detector 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 MSE-HMD85 Hot Metal Detector will operate with 80-240 VAC/50-60Hz or 24 VDC power input. Standard outputs include a cradle relay, a fast reed relay and both NPN/PNP transistor outputs.
