General Description
The MSE-HMD85 Hot Metal Detector 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 MSE-HMD85 Hot Metal Detector 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 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.
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.
