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.

INSTALLATION IMPORTANT: Handle the instrument with great care, especially the probe. Any impact on the probe can damage the vibration system. • Ensure that the slope angle of the material is considered when positioning the probe in the vessel. • When using an extended version for low level alarm, mount the probe above the outlet of the vessel to avoid the probe being dragged along by the outflowing material. • Side mounted units are best installed at an angle. • Avoid mounting the sensor in a recess where buildup could dampen the vibration. • Observe the specifications for bending force(F), torque(M) and pull force(F) as indicated below: Standard: Extended Rigid: Extended Flexible: VXH F • A deflection plate is required when the probe is exposed to falling material or, in the case of a low level switch, when the drag force of the emptying material exceeds the specifications.
