Hokuyo MBX-301CA
Microwave type Close crane warning device
Microwave type not affected by vapor, disturbance light or smoke
- This is a microwave detector. It consists of an antenna as detecting part and control unit composed of oscillator, wave detector and amplifier, and these two components are coupled together by a wave guide. Since the antenna is free from any electronic part which may be affected by heat, it can be used in high temperature environment without being cooled by water.
This device is suitable for using under bad environment because microwave isn't affected by vapor, disturbance light,smoke etc.
This device is reflective type. It is possible to detect small pipe, too.
This device provides monitor output that is monitoring oscillation of microwave.
