Product Specification Model 5318B - Robertshaw …

1 Sales Manual Section 100. Product Specification Model 5318B . LEVEL-TEK. Model 5318B . GENERAL DESCRIPTION. The Robertshaw Model 5318B Level-Tek is a RF. capacitance point (On/Off) level switch, which 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 wide variety of products, including liquids, powders, granular, lump and flake materials. The Product can be either conductive or non-conductive.

2 Probe shown for illustration only. The Model 5318B is self-contained and uses Must be ordered separately. microprocessor based digital circuits to ensure long-term stability, reliability and reduced maintenance. Control signals are provided through the contacts of a DPDT. FEATURES AND BENEFITS. relay. The instrument features adjustable time-delays Versatile - Suits Many Applications- that are individually adjustable for both "Alarm" and Enclosure meets explosion-proof and weather-tight "Return-to-Normal". There are either fixed or adjustable requirements.

3 Choice of supply voltages. differential settings available. The unit is available for Adjustable time delays are standard. either AC or DC supply voltages. All Solid-State Construction - Use of digital solid-state circuits insures long-term stability, reliability, and reduced maintenance. PRICIPLE OF OPERATION Simplified Installation - The standard Model 5318B Level-Tek mounts directly on Self-contained unit may be oriented in any a Robertshaw Probe Assembly, which is installed in the position. Mounts directly on installed tank or other container.

4 A remote mount capability Robertshaw Probe Assembly, connected to probe (maximum 15 feet) exists. The Level-Tek unit senses element by rugged, and convenient, disconnect changes in Product level as a function of the "true" pin. capacitance change between the probe element and the Field Selectable Operational Modes - wall of the container. High Level Fail-Safe, HLFS, or Low Level Fail-Safe, LLFS, is user field selectable. Instrument setup and calibration are done using integral Ease of Calibration and Adjustment - pushbuttons and a 2-line by 8-character LCD display.

5 Built-in LCD display aids in calibration (no external Setpoint calibration can be done without requiring level meter required). changes in the vessel. Convenient Design for Wiring and Maintenance - Plug-in chassis assembly provides easy access The primary measuring circuit employs Robertshaw 's to wiring and terminal board. Heavy-duty patented Pulse Frequency Modulation, PFM, technology. relay. The 12 VDC and 24 VDC rated units accept voltages from 9 to 18V and 18 to 36V, respectively, while the Remote Mount Capability- universal input AC powered unit accepts 100 to 240V.
