VR-21: 7-inch Vibrating Rod

The VR-21 standard piezoelectric driven vibration point level switch possesses a unique single-rod probe design with a sword-shaped blade, in order to prevent bridging of material. It does this by enabling material to easily flow by protecting against buildup on the blade.

Ideal for multiple dry and bulk powder materials, and suitable for both side and top mount applications, the VR-21 has optional hazardous location approvals to CSA standards for Class II, Division I, Groups E, F and G in the US and Canada.

It possesses three sensitivity adjustments: medium and low for materials that may tend to cling to the vibrating rod or heavier materials, and high for light and fluffy materials.

Applications

Detects materials with low dielectric constants and extremely light, fluffy materials

Can be used for low and high level indication, or plugged chute detection

Carbon black, fly ash, plastics, feed, food, chemicals, seed, grain and other materials

Materials densities from 1.25 lb./cu. ft.

Features

Switch selectable high/low fail-safe

Unique ‘blade’ probe design reduces false alarms as a result of buildup

Three sensitivity adjustments

Self-cleaning sensor

No calibration needed

Maintenance and wear free

No moving parts

Remote electronics available

Universal power supply
