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 buildup and requires minimal maintenance. The VR-90 is appropriate for a wide variety of processing industries and is used for high- or lowlevel detection in bulk solids or for detecting the level of sediment settled in a liquid. The VR-90 is suitable for unclassified areas and non-EX environments. It can also be manufactured to meet a wide range of hazardous location approvals. How the VR-90 Works The vibrating element is a polished, round rod made of 316L stainless steel. The vibrating rod of the VR-90 is energized by a piezo drive to vibrate at a set resonance frequency. When material covers the vibrating rod, the amplitude is dampened. The electronics detect this change and generate an alert indicating a full or empty condition. VR-90

Rugged Construction Suitable for Many Materials The VR-90 is typically used to prevent overfilling and for dry run protection. Due to its rugged construction and robust vibration measuring system, the VR-90 is virtually unaffected by the chemical and physical properties of the bulk solid being measured. The VR-90 will also work when subjected to strong external vibrations or when the stored material is changed. It is available in a stainless steel housing for use in food and pharmaceutical products. Simple Setup and Minimal Maintenance The VR-90 is easy to set up in an empty vessel without any...
