~A level switch that detects the interface by the difference in transparency as you can see~

ModelOPT Type 

Main application

  • Interface detection of sewage treatment tanks in chemical factories and food factories, liquid sediments in water treatment facilities, activated sludge, etc
  • Interface detection of two liquids with different transparency
  • Detection of powder with low specific gravity at a level (0.1 or less) that cannot be detected by mechanical or electrical methods
    Example: Fine powder of plastic

Features

  • Both liquids are conductive, there is no difference in specific gravity, and even if the electrical resistance value is the same, the interface can be detected if there is a difference in transparency.
  • With sensitivity adjustment function
  • Easy to change the interface setting position
  • Since it uses an infrared pulse modulation method, it is not easily affected by ambient light.
  • Since the detection part is covered with FEP pipe, it has excellent chemical resistance and is not affected by deposits
  • Cheaper than ultrasonic type level switches

Specification
