Standard 7-Inch Vibrating Rod, piezoelectric driven vibration point level switch, Suitable for both top and side mount applications.
The VR-21 standard piezoelectric driven vibration point level switch has a unique single-rod probe design with a sword-shaped blade to prevent bridging of material by allowing material to easily flow by, protecting against buildup on the blade. Suitable for both top and side mount applications and ideal for a wide variety of dry and bulk powder materials, 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 features three sensitivity adjustments–high for light and fluffy materials, medium, and low for heavier materials or materials that may tend to cling to the vibrating rod.
