Description

Application

With over 6 million Liquiphant point level switches installed globally, this device has proven its daily reliability in the field. Thanks to its active sensor technology, you can always be confident that the device is operating correctly. Additionally, it requires no adjustments when switching between different media.

This point level switch comes with an extension tube and is designed for use with all types of liquids.

  • Process connections: Available in threaded, flanged, and hygienic options (e.g., Tri-Clamp)
  • Temperature range: -40 to +150°C (-40 to +302°F)
  • Pressure range: -1 to +40bar (-14.5 to +580psi)
  • Sensor material: 316L stainless steel
  • Certified for international explosion protection and WHG compliance

 

 


 

Benefits

  • A single measurement solution for any liquid, with easy plug-and-play functionality powered by active sensor technology.
  • Enhanced long-term stability compared to float switches, as there are no mechanical moving parts.
  • Consistent and reliable switching point performance.
  • Versatile application in all pumpable liquids.
  • Maintenance-free operation.
