Industrial Hot Metal Detector used in Rod Mill

INDUSTRIAL HOT METAL DETECTOR USER IN ROD MILL

1. 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.

2. Rear Bar Display 

The rear bar display allows the user to clearly establish the amount of received IR both from the background metalwork and the bar being detected and thereby establishing the correct trip level required. This display also allows the user to align the Detector from a low energy source such as a flashlight, which normally would be insufficient to switch the Detector. Adjustment of both the threshold and the response time is also clearly defined by this bar.
