HOT METAL SENSOR

Hot Metal Detector System

HOT METAL DETECTOR are specially designed to give long and failure free operation in harsh industrial environment and are absolutely maintenance free. It contains no moving parts and is made of quality and tested electronic components totally sealed to the protection class of IP – 65.

Operating Principle

The infrared radiation, received through the lens system, is transmitted to an IR detector. When the radiation exceeds trigger point, the electrical switching output is activated. The Hot Metal Detector electronic circuitry compensates for ambient temperature changes and component aging. Adjustment is therefore not necessary, thus providing higher operational safety and reliability.

Design Features

Hot Metal Detector are rugged infrared switches completely epoxy resin encapsulated in stainless steel housings.
Hot Metal Detector designed to be impervious to the effects of steam, water, dust, shock, vibration and oily conditions
associated with heavy industrial environments. They are temperature compensated for extreme ambient temperature conditions. The hot metal detector are designed to serve and operate anything from 300°c to 1200°c, however distance adjustments is required for each case so as to obtain proper IR radiations.

The sketch above indicates a typical application in a slab mill. The viewing angle determines the
scanned area.

Application

The hot metal detector is an infrared switch especially designed for fault-free operation in the harsh environments of heavy industry. For more than 15 years HMD have been successfully installed to monitor hot products
