Solitel®
Vibrating Rod
Level Switch

D E S C R I P T I O N
Solitel® Vibrating Rod Level Switches provide reliable
level detection of powders and bulk solids. This compact, integral switch is suitable for high or low level
detection in hoppers or silos. It may also be used for
plugged chute detection.
The single-piece probe and the unique self-clean cycle
avoid problems of buildup. Sensitivity of the instrument
can be adjusted to detect a variety of solid materials
ranging from heavy granular materials to light powders
with bulk densities less than one pound per cubic foot.

T E C H N O L O G Y
The Solitel rod vibrates at a frequency of 350 Hz. When
in contact with the media, the vibration is dampened.
The attenuation of the vibration is detected by the integral mount electronics which change the state of the
relay. The unique self-clean feature is activated when
the vibration is dampened. The self-clean circuitry
increases the amplitude of the vibration to dislodge any
buildup which may have occurred.
