Features & Benefits

FEATURES

  • Designed for applications requiring a robust metal housing and larger threads for external mounting
  • Reverse polarity, ESD and transient over-voltage protected
  • Wide supply voltage ranges
  • N and P type output configurations, capable of sinking or sourcing up to 800mA, can directly drive loads
  • Standard and extended temperature ranges available
  • Stainless steel housing with Polysulfone sensing tip
  • Choice of terminations
  • High operating pressure

BENEFITS

  • Solid state so no moving parts to cause unreliability
  • Fast response time
  • Repeatable switching point
  • Built-in output delays available on request for applications where sloshing causes intermittent switching
  • Very robust construction permitting use in a wide range of demanding applications
  • Compatible with most fluids and chemicals

OPERATING PRINCIPLE

Liquid sensing 001_450

When in air the infrared light is reflected back to the detector

 

Liquid sensing 002_450

When in liquid the infrared light is refracted and the output switches
