Liquid Level Switch NWS

The KOBOLD liquid level switch NWS is designed as a 2 and 3-wire switch and can be universally used in vessels and pipelines. The NWS operates on the tuning fork principle in air at resonance frequency. A piezoelectric crystal is used for excitation of oscillations and for monitoring the actual oscillation frequency. When the fork is immersed in liquid, the frequency changes: this change is detected electronically and the output signal is changed. The NWS operates as a 2-wire switch in series with the load. The simple electronic switch is operated by the liquid. The NWS can also be connected to a PLC through a third terminal.
 

Features & Benefits

  • NWS has an output state indicator with an LED that can be seen though a lens in the cover
  • The KOBOLD NWS is ideal for hygienic and sterile applications and for CIP cycles up to 150 °C.
  • The NWS can be set as upper or lower limiter with a mode selector.
