Steel & Heavy Industry Sensors
HMD
The HMD (Hot Metal Detector) is a photoelectric radiation detection sensor that detects the presence or absence of hot materials according to the receiving light of infrared rays radiated from the material, therefore a transmitter is unnecessary.
It is a sensor that can be used under severe conditions like heat, steam, and dust, etc. It's compact size and fiberoptic design makes cooling unnecessary.
CMD
The CMD (Cold Metal Detector) is composed of a transmitter and receiver. It is used even if the object temperature is high and under strong external light.
