Vibrating Fork

 NWP level switch works on the vibrating fork principle. The tuning fork vibrates at a frequency of 400 Hz in air. When the fork becomes immersed in liquid or slurry, the vibration ceases.

liquid level switch NWS is designed as a 2 and 3-wire switch and can be universally used in tanks and pipelines.

 NQ is a compact, ultrasonic level switch which activates when immersed in liquid. Its short intrusion length (1.42”) makes it the right choice for applications in which container size is limited.
