LZ Cable Float Level Switch

A. Product Overview

The Baumer LZ Cable Float Level Switch is a simple and durable liquid level switch used to detect high level, low level and switch differential levels in tanks and reservoirs. It is designed with a hermetically sealed and moulded body, making it suitable for regular industrial and utility applications where dependable liquid level control is required.

The float and counter weight are made from polypropylene, which helps protect the switch from corrosion in water and similar liquid applications. The standard version comes with a PVC cable, IP68 enclosure protection, vertical mounting and SPDT switch output. It is commonly used in storage tanks, reservoirs, sewage treatment plants, water treatment plants and automatic pump control systems.

Key features include:

• Hermetically sealed and moulded construction
• Adjustable counter weight
• Micro switch operated design
• Easy installation
• Non toxic material
• Polypropylene float and counter weight
• PVC cable
• IP68 enclosure
• SPDT switch type
• 16 A 250 VAC electrical rating
• Maximum operating pressure up to 4 bar
• Maximum operating temperature up to 60°C
• Available cable lengths such as 3 meter, 5 meter, 10 meter and 20 meter

B. Working Principle

The Baumer LZ Cable Float Level Switch works on a float tilt mechanism. The float is installed inside the tank with its cable and counter weight. As the liquid level rises or falls, the float moves with the liquid surface.

When the float tilts due to the change in liquid level, the internal micro switch changes its contact position. This allows the switch to operate from Normally Open to Normally Closed or from Normally Closed to Normally Open depending on the wiring and application requirement.

This switching action can be used to start or stop a pump, trigger a high level alarm, activate a low level alarm or control filling and emptying operations. The same switch can also be used as a multi point level switch in suitable tank control applications.

C. Why It Is Used

The Baumer LZ Cable Float Level Switch is used because it provides a simple, reliable and cost-effective method for liquid level detection. It does not require complex programming or advanced electronics, making it easy to install and maintain.

It is mainly used for:

• Detecting high liquid level in tanks
• Detecting low liquid level in tanks
• Automatic pump start and stop control
• Preventing pump dry run
• Preventing tank overflow
• Controlling filling and emptying operations
• Monitoring water levels in reservoirs
• Level switching in sewage and water treatment plants

The polypropylene construction helps reduce corrosion problems, while the IP68 enclosure makes it suitable for demanding tank environments. Its SPDT contact output allows flexible connection with pumps, alarms, control panels and automation systems.
