Item # 730-5133, VR-51

The VR-51 extended vibrating rod uses a steel-rope reinforced cable and allows for insertion lengths from 19 inches up to 19 feet. This vibrating rod with a flexible extension is custom manufactured to the desired length specification at the BinMaster factory. The VR-51 is intended for top mount applications and can be used to detect materials that are heavy, medium or light weight including those which are extremely light and fluffy.

Consistent in design with other BinMaster vibrating rods, the VR-51 features a unique single-rod probe design with a sword-shaped blade to help prevent the bridging of material, making it superior to typical “tuning fork” designs by allowing material to easily flow by and prevent build up on the blade. Other benefits include a self-cleaning sensor, switch selectable high/low fail-safe, and an auto sensing power supply which can accommodate 20 up to 250 volts AC/DC. Remote electronics via a point level alarm panel are available to alert to bin levels for four up to 24 individual sensors.
