HMD Hot Metal Detector
HMD Sensing System
The HMD Sensing System is a Hot Metal Detector for
material at temperatures over 500°C (932°F). Thanks
to its two parts design, it is able to detect products
which are not in its direct field of view (due to physical
obstructions, limited space, etc.), even in areas of high
Because of its rugged design it withstands the severe
environmental conditions of the steel industry.
Main HMD Unit HMD-01
This is main HMD system unit containing Electronic
Circuit which Process the signal collected by Sensor Unit
and produce the Output. The Electronic Circuit includes
the regulated power supply, detected signal amplifier
and relay output.
Sensor Unit Sensor S-01
Sensor unit receives power from the Main HMD Unit, HMD01, and detects the infra-red energy
emitted by the object, reconditions it suitably and send it to Main HMD Unit for further processing and generating the output.
Principal of operation
The infra-red radiation emitted by the hot product is collected by the photosensitive element
present in the Sensor unit S01. The photocell signal is processed by the electronic circuit present in the Main HMD Unit HMD01 which outputs the detection signal.
