The VR-41 vibrating rod level sensor is approved in the U.S. and Canada for CSA standards for Class II, Division I, Groups E, F and G for hazardous locations. Enclosure type certifications for these models include NEMA 4X, 5 and 12. This vibrating rod level switch is used to detect high-, mid- and/or low-level in bins, silos and hoppers containing powders or dry bulk solid materials. The single-rod probe design features a sword-shaped probe that resists bridging of material that can occur with tuning forks designs. This piezoelectric-driven vibrating rod has very low energy, so it won't "dig a hole" and cause a false alarm. It features three sensitivity settings and can reliably detect very light materials with bulk densities down to 1.25 lb/ft3. It has dual conduit entries for easy wiring, an LED status indicator light to indicate sensor status and a switch-selectable high/low fail-safe.
