GENERAL DESCRIPTION

The Robertshaw Model 314B Level-Tek is an all solid state RF control instrument providing ON/OFF control with two independently adjustable setpoints each with its own output control relay. For use with a vertically mounted probe assembly, the independent and non-interacting control points may be adjusted throughout the length of the probe up to the limits of the capacitance range.

This true "duplex" or dual Level-Tek provides application versatility with cost and space savings not previously obtainable. Available by order in fail-safe control modes for "High" and "Low", "High" and "High-High", or "Low" and "Low-Low". The operational mode may be changed in the field by soldered jumper connections on the chassis assembly.

The Model 314B has two independent set-points, each with adjustable differential. The Set-point and Differential adjustments are by means of nominal 20 turn sealed potentiometers with light-emitting diodes on the chassis assembly to indicate relay operation as an aid in calibration.
