The
NQ - SS Ultrasonic Level Switch series is a compact, ultrasonic
level switch which activates when immersed in liquid. Glass
fibre reinforced nylon and 316 SS construction (in a NEMA
4X housing, of course!) make the NQ a tough performer in industrial
applications.|

KOBOLD Model DWU, DWS and DWP Paddle/Bellows Flow Meter and
Switches are based on the paddle, or static plate, principle.
This type of arrangement is ideal for use in applications
where dirt and solid grain contaminants are of concern. The
paddle-bellows arrangement offers large internal clearances
and mechanical insensitivity to a wide range of particulate
matter.|
KOBOLD's NWS - Vibrating Level Switches are compact, vibrating fork level switches which are 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 NWS - Vibrating Level Switches 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. >>> Learn More <<< |
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.
