General Description
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 a transistor switch or 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 RL-
5900 series power supply/relay module.
