The VRFII-SG-F8 is a flush-mount, standard-capacitance level switch used to detect the presence or absence of dry bulk materials in bins, hoppers, or silos. It uses radio frequency (RF) capacitance technology to sense changes in material levels without moving parts, making it ideal for rugged industrial environments.
