Mounting Location

Use vibrating rods to detect high levels by mounting them on the roof of the vessel. Alternatively, they can be mounted on the side for high, mid, or low-level alerts. Used in the cone of the bin or a hopper, they can detect when the vessel is almost empty.

Mounting Plates

Vibrating rods can be mounted on flat or sloped bin roofs. Powder-coated carbon steel mounting plates are available in 0°, 5°, 10°, and 30° angles. For mounting in the cone or on the side of the bin a 0° mounting plate is used.

Standard 7-inch

The VR-21 is the standard, in-stock model featuring a sword-shaped blade and a 7.37” insertion length. It is used for top and side mounted applications, plugged chute detection, or is installed in the cone of the vessel for low level detection of powders and solids.

Rigid Extended

The top-mounted VR-41 can be extended from 13” to 13’ using a galvanized, stainless steel or a sanitary pipe extension. It is used for level or plugged chute detection in heavy, medium, and light materials. It is sensitive enough to detect light fluffy materials with a dielectric as low as 1.25 lb./cu. ft.

Sediment Detection

The SED model is used to detect the level of settled sediment or solid materials in a tank of liquids. The sediment option is available for the standard-length VR-21 SED and VR-41 SED which can be extended with a rigid extension from 13” up to 13’.

Flexible Extended

The VR-51 features a steel-rope reinforced cable that can be extended from 19” to 19’ down into the vessel. The flexible extension resists damage from falling material. This top-mounted model is custom built to customer specifications.

Sanitary Environments

The VR-31 is designed for food or pharmaceutical use. This model features a 2” sanitary stainless-steel fitting for use with a tri-clamp for clean-in-place applications. It can be customized with an optional stainless-steel extension in lengths from 13” to 13’.

Round Rod for Coarse Solids

The VR-90 features a round, stainless steel rod suitable for coarse-grained solids and granules. It can also be used in food and pharmaceuticals when ordered with the stainless-steel enclosure option. The VR-90 is a good option for vessels where the material is changed often. It is available with hazardous location approvals should they be needed.

Vibrating rods work by using a piezoelectric element to vibrate the blade.

The blade vibrates when there is no material covering it. Once the blade is covered, the vibration is dampened.

This triggers an electronic circuit to force a relay switch that indicates a covered condition.

Conversely, when material falls away from the blade, vibration resumes, and the relay indicates an uncovered condition.
