Level detection with optical sensors

• Chemical resistance
  • Sensor housings made of polysulfone or stainless steel to resist specific liquids
• Media recognition
  • Liquid detection by optical light which allows for detection of diverse, even non-conductive liquids
  • In leakage control, just 1 ml leaking fluid suffices to trigger an alarm
• Easy commissioning
  • No configuration required in sensors with integrated electronics.  Fiber-optic sensors are configured a fiber optics
• Hazardous environments
  • The intrinsically safe fiber optic variant with PFA coating is suited for huse in hazardous environments
• Fail-safe behavior
  • The integrated fail-safe behavior will trigger an alarm in the event of leakage, cable break, sensor error or sensor detachment 

Sensor capabilities in chemical resistance open up versatile application fields:

• Level control of liquids such acetone, acid, lye, mineral oil, milk and any non-conductive fluid
• Non-contact level detection in (semi-)transparent tubes and ascending pipes
• Minimum and maximum limit detection in troughs and tanks
• Leakage control in oil troughs or lubricant tanks
• Liquid leakage control in dispensers and other liquid handling systems
