The LUS211 is a non-contact programmable sensor that is used to measure solid and liquid level in an enclosure. The sensor shows either the distance to the top of the material, the volume of material in the vessel, or the fill percentage of the vessel once the tank geometry is specified in the programming menu. The value is displayed on an integrated multi-color display while the outputs communicate critical process information to a control system via a simple switching or analog output or via IO-Link communication.
