Hot Metal Detectors (HMD)
The HMD (Hot Metal Detector) is a photoelectric sensor of the radiation photo-detection type of the heat material that detects presence, and detects the position according to the receiving light of the infrared rays (heat ray) radiated from the heat material (scorching object). The transmitter is unnecessary.
It is a sensor that can be used under a severe use condition that heat, steam, and dust, etc. disperse like the ironworks and the heavy industry site, etc.. It is easy to handle this sensor in a small size, unnecessary cooling and using a fiber optic cable as receiver.
