Robertshaw Model 5318B

The Robertshaw Model 5318B Level-Tek is a RF capacitance point (On/Off) level switch, used to detect level changes in liquids and solids. Bare Probes can be used for non-conductive liquids while the TFE coated probes can be used for conductive liquids and powders. The Model 5318B is capable of detecting the level in a wide variety of products, including liquids, powders, granular, lump and flake materials in tanks, sumps, silos and in cooling tower applications.

All the models have a DPDT relay, fixed & adjustable differential and adjustable time delays and are in explosion proof, weather tight enclosures. Capacitance Probes are ordered separately depending on the application. In most cases the existing probes will work with the 5318B.

The most common model configurations have a ½ NPT Probe Hub and are painted in Nitro Blue.

Common Model Configurations

MODEL 5318B-B1-A Supply Voltage: 85 to 265 VAC

MODEL 5318B-A1-A Supply Voltage: 18 to 36 VDC

MODEL 5318B-C1-A Supply Voltage: 9 to 18 VDC


The 5318B is also available with Grey Epoxy paint and ¾ NPT Probe Hub.

FEATURES AND BENEFITS

    5318B Capacitance level Controller and display
  • Versatile - Suits Many Applications- Enclosure meets explosion-proof and weather-tight requirements. Choice of supply voltages. Adjustable time delays are standard.
  • All Solid-State Construction - Use of digital solid-state circuits insures long-term stability, reliability, and reduced maintenance.

REMOTE MOUNT OPTIONS

For remote mount of 5318B (maximum 15 feet) select cable/probe conduit outlet box assemblies below. Coaxial cables are used with standard units/probes

COAXIAL CABLE ASSEMBLIES:
[032KX050-XX] - Coaxial Cable, Teflon Insulated, with explosion proof/NEMA 4 probe conduit outlet box. Maximum temperature 350º F
[032KX080-XX] -Coaxial Cable, Teflon Insulated, with explosion proof/NEMA 4X (Gray Epoxy painted) probe conduit outlet box.
REMOTE CALIBRATION
[909GM201] - Remote Calibration Kit – includes Software CD and Cable

NOTES

  1. The remote mount cable is not UL/c-UL certified. Use of the remote mount cable with the 5318B voids the UL/c-UL certification/explosion proof rating of the instrument.
  2. Maximum length on any cable is 15 feet.
  3. Cable/probe conduit outlet box must be used with remote mounted 5318B Level-Tek
  4. Length pricing per foot or any portion thereof.
