Vibrating Rod for Hazardous Locations
The VR-90 is a vibrating rod used for level indication in granular and coarse-grained bulk solids contained in bins, tanks, silos, and hoppers. It features a round, stainless steel rod that resists build-up and requires minimal maintenance. The VR-90 is appropriate for a wide variety of processing industries and is used for high- or low-level detection in bulk solids or for detecting the level of sediment settled in a liquid. The VR-90 is suitable for unclassified areas or can also be manufactured to meet a wide range of hazardous location approvals.
