Product Shipping Subject to Factory Availability Need Specifications? See PDF Section Below.
Robertshaw Model 5318B-A1-A 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-A1-A 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-A1-A 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 DC supply voltages.

GENERAL DESCRIPTION The Robertshaw Model 5318B-A1-A 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-A1-A 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 DC supply voltages.
PRINCIPLE OF OPERATION
The standard Model 5318B-A1-A Level-Tek mounts directly on a Robertshaw Probe Assembly, which is installed in the tank or other container. A remote mount option (maximum 15 feet) is available.
The Level-Tek unit senses changes in product level as a function of the ”true” capacitance change between the probe element and the wall of the container.
Instrument setup and calibration are done using pushbuttons and an integral, internal, 2-line by 8-character LCD display. Setpoint calibration can be done without requiring level changes in the vessel. The primary measuring circuit employs Robertshaw's patented Pulse Frequency Modulation, PFM, technology. The 24 VDC powered unit accepts voltages from 18 to 36V. No jumper, or switch, changes are required.
