Liquid Level Sensors

Liquid Level Sensors

  • Detect liquids regardless of conductivity, color, or specific gravity
  • Economical and compact—built-in solid-state switching electronics
  • One-unit installation—simply screws into the top or side of your tank

These dependable, electro-optic level sensors contain no moving parts to clog or wear. Sensors offer ±1 mm repeatability and are available in a wide variety of materials to meet even the most demanding applications.
Installation is simple and quick through the tank top, bottom, or side. The switches can be used for low-, intermediate-, or high-liquid level detection. Solid state switching ensures dependability over a long service life. Order controller separately.
