Bamo NIVASWITCH Vibrating Fork Level Detector

Bamo NIVASWITCH Vibrating Fork Level Detector is easy to use and can detect most liquids. It works independently of electric conductivity, clogging, turbulence, flow-rate and air bubbles. The trigger point depends of the immersion depth.

Robust and compact, NIVASWITCH may be mounted vertically or horizontally Easy to install, it does not require maintenance. Status of output is indicated by a bi-color (LED) and a function test is performed with a magnet The alternative current output or digital output (NPN or PNP) can be connected to a PLC. As an option, the relays PKK or LC1, allow to convert the output as a potential free contact signal.

Bamo NIVASWITCH Features

  • Detection of level for liquids
  • Continuous monitoring
  • Operating even with turbulence
  • Unnecessary calibration routine
  • Operating even with suspended solids


NIVASWITCH is a liquid level detector. It is mainly used for overfill protection, leak detection or dry run protection of pumps.
