Hole Detector


Successor model of pinhole detector P100.
It provides brandnew HMI & maintenance functions.



  1. As a detection sensor, a photo-multiplier is adopted and minimum 15μm or more hole is detectable.
  2. A general-purpose sequence controller is adopted as a signal processing system, it increases maintainability.
  3. An attached computer performs calibration and displays of various status. It is connectable and operatable to both equipment cabinet and a detection unit.
