Vibrating Rod Switches - 1

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. • Single rod design eliminates clogging Powders and bulk solids with maximum particle size of 1⁄2 inch (10 mm) including: • High temperature version up to +320° F (+160° C) • Self-clean cycle and polished probe minimize solids buildup • Plastic powders and pellets • Class I, Div. 2 and Class II, Div. 1 approval • Pulverized coal • Adjustable sensitivity allows easy calibration for various bulk densities • Extended rigid probes up to 100 inches (2540 mm) • Extended flexible lengths to 65 feet (20 meters) • Aerosil® (fume silica) • Wood chips and sawdust • Cement, lime
