  • Safety Approvals - For hazardous locations

GENERAL DESCRIPTION

The Robertshaw Model 5318B Level-Tek is a RF capacitance point (On/Off) level switch, that employs all solid state electronics for detecting predetermined product level changes in tanks, sumps, silos and other vessels or containers. The Model 5318B is capable of detecting a variety of products, including liquids, powders, granular, lump and flake materials. The product can be conductive or non-conductive.

The Model 5318B is self-contained and uses microprocessor based digital circuits to ensure long-term stability, reliability and reduced maintenance. Control signals are provided through the contacts of a DPDT relay. The instrument features adjustable time-delays that are individually adjustable "Alarm" and "Return-to-Normal". There are either fixed or adjustable differential settings available. The unit is available for either AC or DC supply voltages.
