The HMD (Hot Metal Detector) is a photoelectric sensor of the
radiation photodetection 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 by a small size, unnecessary cooling and using
a fiber optic cable as receiver. |

| The CMD (Cold Metal Detector) is composed of the transmitter
and receiver. It is used even if the object temperature is high and under strong
external light. |

 |
| The punch hall detection sensor (weld point detector) detects
the punch hall installed in the welding part of the coil (steel board) that runs
continuously between the transmitter and the receiver. |
