Vibrating Rod Level Sensor Includes Three Sensitivity Settings
BinMaster Level Controls’ standard VR-21 vibrating rod level sensor and solid extended VR-41 vibrating rod level sensor have been approved in the U.S. and Canada to CSA standards for Class II, Division I and 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 detects high-level, midlevel and /or low-level in bins, silos and hoppers containing powders or dry bulk solid materials.
BinMaster’s 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 detect very light materials with bulk densities down to 1.25 lb./ft.3. It has dual-conduit entries, 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-inch probe and can be used for low-level, midlevel and high-level detection. The VR-41 handles 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 feet.
