KOBOLD Instruments, Inc. NWP - Plastic Vibrating Fork Level Switches

Product Features All Plastic Construction Tolerates Foaming, Turbulence and Coatings Reliable Solid State Design No Wear Components NEMA 6 rating KOBOLD's 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. This cessation is detected by the electronics which activate the SPST relay. The robust vibrating fork technology provides a reliable switch for a multitude of tough applications and is suitable for use with foaming, turbulent and some coating media. The all solid-state design affords the user the ultimate in reliability. A chemically resistant all-plastic design makes it ideal for use with many aggressive liquids. Should your application require a higher power switching capability, a 10 amp relay output is available through use of the optional RL-5900 series power supply/relay module.
