GENERAL DESCRIPTION
The Robertshaw Model 318A Level-Tek is an on/off all
solid state RF control instrument for detecting predetermined product
level changes in tanks, sumps, silos and other vessels or containers. The
Model 318A 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 318A is self-contained and uses integrated
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-delay which is selective
for time-delay on "Pull-In," "Drop-Out" or both. The unit is available
with any of three different supply voltages.
