RF Level Switch
Level Switch

Babbitt RF Level Switches have many advantages over other technologies used for level sensing:

  • Ideal for use in both liquids and bulk solids.
  • Rugged construction for the roughest industrial applications. These products perform in high temperature, high pressure, high vibration, dirt and sludge and many other applications requiring sturdy, high-quality design.
  • Solid-state electronic sensing has no moving parts.
  • RF technology ignores significant product build-up on the probe.
  • Simple installation and calibration.
  • The probe length is easily modified.
  • The modular electronics are easily serviced.
  • Explosion-proof housing is standard.
  • Customizable for extreme applications.
  • Custom probe assemblies have been made for high temp (2000 deg F), high pressure (2500 psi), shielding for excessive EMI, hot-removal (remove probe while vessel is pressurized), rail-car loading, and many others.

These switches employ a radio frequency (RF) balanced impedence bridge circuit to detect if the probe is in contact with the material that is to be sensed. A high-frequency/low-power radio signal is emitted by the electronics in the head of the level switch. The probe serves as an antenna to detect the frequency. Calibration is done when material is not in contact with the probe. The bridge is balanced by turning the adjustment pot to find the bridge balance threshold. When material comes in contact with the probe, the bridge becomes unbalanced and the comparing circuit realizes the change. This causes a relay output to change state.
This relay output may be used for high or low level alarming, or to control level by turning pumps on or off or by opening and closing valves.

Typical Applications: These level switches may be widely applied for liquids, dry/solids and slurries. They may also be used in interface applications such as foam/liquid and oil/water.

  • Liquids: Water/Wastewater Fuels Petroleum Products, Acids, Caustics
  • Interface: Oil/Water, Crude/Brine, Foam/Liquid
  • Dry/Bulk Solids: Fly Ash, Cement, Plastics, Flour, Powders, Sand, Grain, Carbon Black, Wood Chips
