Functionality

The operating principle of an analog level sensor with a reed chain in combination with a float leverages the upward and downward movement of a float according to the liquid level. The level sensor consists of a reed chain and a float. The reed chain is made up of multiple individual reed switches arranged at regular intervals along a flexible metal strip. Each reed switch comprises two ferromagnetic contacts separated by a glass enclosure.

The float is a buoyant body that rests on the liquid surface and moves up or down with the level. Equipped with a magnet, the float interacts with the vertically positioned reed chain inside the container. As the liquid level changes, the magnet moves along the reed chain. The individual reed switches respond to the magnetic field of the float. When the magnet approaches a reed switch, the contacts close, generating an electrical signal. This signal is then captured by a measurement device or evaluation unit and converted into a measurable value.

Applications

Lubrication and Cooling

Analog level sensors with reed chains are critical for monitoring fluid levels in cooling, hydraulic, and lubrication systems. They ensure precise control of coolant, oil, and lubricant levels, maintaining optimal performance of machinery and systems. These sensors provide early warnings of low levels or leaks, preventing damage, reducing wear, and extending the lifespan of machine components.

Water Treatment and Fuels

Analog level sensors are indispensable in water and wastewater industries as well as in combustion engine systems. They enable precise level measurement in water tanks, wastewater treatment plants, and fuel tanks. This ensures efficient operation, minimizes fuel loss, and reliably monitors water levels, guaranteeing system performance, safety, and uninterrupted operation.

Filling Systems and Chemicals

In the chemical, pharmaceutical, and food and beverage industries, precise level measurement is essential. Our analog level sensors enable accurate monitoring of chemicals, solvents, liquids like water, milk, and oils, as well as pharmaceutical products. They ensure efficient process control, optimize resource use, and contribute to consistent product quality and compliance with production standards.

Industries

Analog level sensors with reed chains have versatile applications across multiple industries. They are commonly used in water and wastewater management to precisely monitor tank levels. In the chemical and food industries, they ensure safe and hygienic processes. Additionally, they are employed in the oil and gas sector and maritime applications, where precise liquid level measurement is essential. These sensors also play a vital role in heating, ventilation, and air conditioning (HVAC) systems for efficient fluid level control and regulation.
