Liquid level sensor with high-end featuresThe LevelPro Modular Series liquid level sensors offer high-end features without high prices. Interchangeable electronic modules allow simple field changes or repairs without fluid loss. This is desirable with expensive, pressurized or environmentally hazardous fluids like CFCs.

All LevelPro modular series liquid level sensors meet the following specifications:

  • Operating temperature -20°F and +230°F (non-freezing liquids).

  • Fluid compatibility is determined by seal and housing material selection.

  • Models with metric/unified threads will mate with SAE type fluid ports.

  • Maximum fluid pressure on prism face = 400 P.S.I. @ 70°F.
  • Maximum load current not to exceed 25 mA including inrush transient.
  • 22 AWG PVC jacketed cable with 24-inch length (red, green, black).
  • Select supply voltage from chart. Do not reverse polarity or damage to sensor may occur.

Modular "C" Series

Liquid level sensor with high-end featuresThe conduit feature permits shielded installations which protect the wiring and electronics from mechanical and environmental hazards.

All LevelPro modular "C" series sensors meet the following specifications:

  • Operating temperature -20°F and +230°F (non-freezing liquids).

  • Fluid compatibility is determined by seal and housing material selection.

  • Models with metric/unified threads will mate with SAE type fluid ports.

  • Maximum fluid pressure on prism face = 400 P.S.I. @ 70°F.
  • Maximum load current not to exceed 25 mA including inrush transient.
  • 22 AWG PVC jacketed cable with 24-inch length (red, green, black).
