Working Principle:

• Conductivity level limit switches are static rendered furnished devices with no moving parts.
• A low voltage sine-wave is provided into the liquid using a reference rod (or electrode).
• The electronics continuously scans the sense rod (or electrode) for the presence of sine-wave signal on it.
• As soon as liquid bridges the two electrodes, the signal appears on sense-electrode.
• Device gives the switching output by analyzing the received signal at sense electrode.
