Description

The LFL2-CK-U-PVC5 Float Switch operates on a mechanical principle where a polypropylene float, containing a micro-switch with a switching ball, activates when the float’s orientation moves beyond a specific horizontal switching angle. This action opens or closes the electrical circuit, providing a clear signal for high or low liquid level detection. The device is engineered for stable performance in demanding industrial environments.

Its construction is suited for integration into process automation systems, PLCs, and control panels. The 5-meter PVC cable offers installation flexibility, allowing the sensor to be positioned at the required level within a tank. The switch’s specifications ensure compatibility with common industrial control voltages and its robust design handles a variety of liquid media.

Key Features

  • Cylinder-type float switch with a compact 29.2mm outer diameter for installation in confined spaces.
  • Micro-switch mechanism ensures high repeatability and long operational life for limit value signaling.
  • PVC-jacketed, highly flexible 5-meter cable simplifies routing and connection to control systems.
  • Polypropylene float material provides chemical resistance against water, wastewater, and many aggressive liquids.
  • Rated for pressures up to 3 bar, suitable for use in pressurized vessels and pipelines.
  • Broad operating temperature range from -20°C to +70°C ensures reliability in varied climatic conditions.
  • Designed for tool-free side mounting via a standard G1 threaded tap hole.

Applications

  • High- or low-level limit detection in industrial water storage and processing tanks.
  • Level monitoring in wastewater treatment plants and chemical holding vessels.
  • Overflow protection and pump control in agricultural irrigation and drainage systems.
  • Liquid level signaling in food & beverage processing equipment.
  • Safety interlock for fluid levels in machinery coolant systems and industrial boilers.

Frequently Asked Questions

What is the maximum voltage and current this float switch can handle?

The Pepperl+Fuchs LFL2-CK-U-PVC5 float switch is rated for a switching voltage of up to 250 volts AC or 250 volts DC. The maximum switching current it can handle is 3 amps. These ratings make it suitable for direct interfacing with industrial relays, contactors, and PLC digital input modules without requiring additional signal conditioning.

How do I install this float switch and what are the mounting requirements?

This cylinder-type float switch is designed for side mounting through a standard G1 threaded tap hole. The installation is tool-free; you simply thread the sensor's body into the prepared hole. For top mounting, additional accessory kits may be required. Ensure the float has free vertical movement and is not obstructed by tank internals for accurate level detection.

What types of liquids is this sensor compatible with?

The sensor is designed for use with a wide range of liquids, including water, wastewater, and many aggressive fluids. The polypropylene float material offers good chemical resistance. However, for specific aggressive chemicals or solvents, you should verify the chemical compatibility of polypropylene and PVC with your medium to ensure long-term sensor integrity.

What is the pressure and temperature operating range?

The float switch has a pressure rating of up to 3 bar (approximately 43.5 psi), allowing it to function in pressurized vessels. Its operating temperature range is from -20°C to +70°C, providing stable performance in both cold and moderately hot industrial environments without risk of damage to the internal micro-switch or sealing.
