Measuring level
Measuring level

Whether it's continuous fill level measurement, limit value detection or both combined: Balluff offers a wide range of solutions for process control, storage or protection. Depending on the installation situation, media properties and environmental conditions, we offer optimum sensors that only have one goal: Efficient processes.

You can choose between contact-free or with contact. Balluff sensor technology can also be used to measure the fill levels of liquid, paste-like and granular media through tank walls. Our sensors also satisfy the strict regulations of the food and pharmaceutical industries as well as medical technology.

  • Monitor blood levels in a heart-lung machine with smart level technology

    Individually applicable sensors for the oxygenator

    The solution

    The blood level in an oxygenator is monitored in two stages using a reference and minimum value. Our BCS capacitive sensor indicates when the blood level drops below the minimum value. It is attached using adhesive tape that has been applied to the blood reservoir. This allows it to be reused multiple times. It's position can be selected freely. Deposits are disregarded thanks to smart level technology. This makes it so that the actual blood level is monitored and the doctor can keep it at the right level.

    The features

    • Housing design in accordance with medical standards
    • Detect blood and other liquids non-contact while maintaining sterility
    • Reliably compensate for deposits and foam
    • Adhesive tape allows them to be reused multiple times and used individually
    Life science, individual and fully customized products, monitoring blood levels in a heart-lung machine with Smart Level technology

  • Monitor the fill levels of oil and coolant

    More reliability for your gearbox, hydraulic, and cooling systems

    The solution

    Optimum fill levels should always prevail in the expansion tanks of the cooling system and of the gearbox and hydraulic system. Our BCS capacitive sensors detect the maximum and minimum fill levels without direct contact – through the container wall or with the help of adapters. They are installed in the oil pan as a leak sensor and reliably report an oil loss there.

    The features

    • HALT tested capacitive sensors
    • Contact-free measurement through plastic walls
    • detect oil and water
    Energy, wind power, monitoring the fill levels of oil and coolant

  • Level monitoring of charges and coke

    Level monitoring of charges and coke

    The solution

    Extremely reliable and precise under extreme conditions: this is how BUS ultrasonic sensors from Balluff do their job. This makes them perfect for controlling the stack heights on conveyor belts as well as levels in silos. Unaffected by the harsh conditions in a steel plant, they detect objects made of many different materials and ensure you of reliable blast furnace charges even around the dust and dirt from burden material and coke.

    The features

    • Contactless detection
    • Irrespective of color, transparency, reflection properties and surface finish on the object
    Level monitoring of charges and coke

  • Monitor levels without contact on by-pass tubes

    Monitor levels without contact on by-pass tubes

    The solution

    You can also prevent overflow of tanks with aggressive chemical contents or too low a level by monitoring levels with the help of by-pass tubes. Install our compact capacitive sensors on the by-pass tube using cable ties. This is simple and inexpensive. To compensate for foam and build-up there are high-end versions for you which reliably detect highly conductive media such as lyes.

    The features

    • For acids, bases, ultrapure water and slurry
    • Smart Level technology for foam and build-up compensation

  • Detect process fluids with media contact

    Detect process fluids with media contact

    The solution

    When the container wall won’t allow detection from the outside, our capacitive sensors in the PTFE housing are the right choice. These detect the level of highly conductive media such as acids and bases directly in the process fluid. This means for example that etching or application of a resist, developing after lithography, or chemical-mechanical polishing and cleaning of the wafer can begin as planned.

    The features

    • PTFE housing for high chemical resistance
    • For acids, bases, ultrapure water and slurry
    • Smart level technology for foam and build-up compensation
