BinMaster Level Controls offers the standard VR-21 vibrating rod level sensor and solid extended VR-41 vibrating rod level sensor with approvals in the U.S. and Canada to 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/cu ft. 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. The VR-21 model has a standard 7.37-in. probe and can be used for low-, mid-, and high-level detection. The VR-41 is used for high-level detection and is mounted on the top of the bin. It features a rigid, extended probe that can be custom made in lengths up to 13 ft.
