Waveguide type sensor



Microwave type not affected by vapor, disturbance light or smoke

Feature

  • 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.
