Vibrating Level Switches

The NWS - Vibrating Level Switches works on the
vibrating tuning-fork principle. A
piezoelectric crystal is matched to the
frequency of a tuning fork in air, and
used to set the fork vibrating.


KOBOLD's Series NWS is a compact, vibrating fork level switch which is suited for use with non-viscous and viscous liquids as well as many types of fine granular solids. The switch employs an forked probe which vibrates at approximately 1200 Hz. When the probe is immersed in a medium, the resonant frequency is dampened. This frequency shift is sensed by a detecting circuit and results in activation of a solid state switch or SPDT relay depending on the model.The Series NWS may be configured as either two-wire or three-wire controller and is switchable from a normally-open to normallyclosed (wet-on or dry-on) switch function. Its solid-state design uses no moving parts in the sensor or switch portions, making the switch exceptionally reliable

The NWS - Vibrating Level Switches is available in fitting sizes frm 2" 3/4" NPT NWS-5220
2" 1" NPT NWS-5225
