DWYER VRLS vibrating rod level switch

FEATURES

• Probe design allows for self-cleaning, ensuring no build-up or bridging of material and accurate detection
• No mechanical moving parts with no routine maintenance required
• Sensitivity is adjustable for detection ranging from large granular material to small powders with low bulk densities
• The failsafe mode can be set for failure on high level or failure on low level using a selector switch in the enclosure
• Unaffected by the dielectric constant of the sensed material, making it superior to a capacitance level switch for applications where the dielectric constant is too low, where there is more than one material being used in one vessel, and when material moisture content can change
• Ideal for applications where the bulk density is too low for a rotating paddle level switch
