Technologies to ensure proper chemistry levels

Balluff offers the broadest portfolio of sensors in the market to solve applications with technologies that fit and perform reliably and consistently. These sensors can withstand and accurately detect the harsh chemistries used in the semiconductor industry.

Balluff sensors not only precisely turn on when levels are present but they turn off when levels are absent. With a patented hybrid capacitive technology, detecting acids bases and other water-based conductive liquids is assured. These sensors ignore moisture, foaming, material buildup and filming. This ensures that your processes take place not only reliably, but also efficiently and economically.

Application examples

  • Indirect liquid level detection

    Liquid level detection through nonmetallic container walls

    The solution

    The semiconductor industry utilizes a wide variety of liquids and chemistries. These liquids can be highly conductive acids, bases, and deionized water. Balluff's unsurpassed industry leading capacitive technology reliably detects these liquids when present and accurately turns off when absent. Offering a patented hybrid capacitive technology, these liquids can be detected through nonmetallic walls up to 10 mm thick. In addition, they are not affected by moisture, foaming, filming and material buildup.

    The features

    • Reliably detects various chemistries
    • Nonmetallic container walls up to 10mm thick are ignored
    • Moisture, humidity, filming, foaming and material buildup are
    Contact-free fill level detection in the semiconductor industry

  • Accurate noninvasive point level detection

    Reliable level detection through sight glass

    The solution

    Balluff capacitive sensors detect fill levels of acids, bases or deionized water without contact through sight-glasses. Balluff's hybrid capacitive technology compensates for moisture, and foaming. Block style sensors can be installed quickly and easily with cable ties or sight-glass mounts are available for tubular style sensors.

    The features

    • Detection of acids, bases and deionized water
    • Foam and deposit compensation using hybrid technology
    • Fast, easy and cost-effective mounting
    • IO-Link variant on request
    Contact-free fill level sensing at bypass pipes

  • Invasive or direct level detection

    Level detection in direct contact to media

    The solution

    In the semiconductor industry level detection in direct contact with media is not a preferred method. However in waste tank level applications direct contact is not an issue. Balluff offers the widest variety of capacitive sensors and mounting methods in the market. Complete Teflon (PTFE) sensors with Teflon switch wells would be the ideal solution for this application. Balluff's hybrid capacitive technology offers the most reliable solution as it would ignore the filming and material build up on the sensor and switch well.

    The features

    • Hybrid capacitive technology
    • Housings available in Teflon
    • Filming and material buildup compensation
    Reliably detect highly conductive process fluids

  • Fill level measurement in tanks

    Continuous and highly accurate level detection

    The solution

    Balluff's magnetostrictive linear position sensors detect the fill level of your tanks with high precision and micrometer resolutions. The measurement section is protected by a pressure-rated stainless steel tube. Balluff thereby guarantees you absolute reliability and measurement results of the highest possible quality.

    The features

    • Absolute level measurement A
    • bility to measure separating layers
    • Stainless steel magnetostrictive linear position sensor
    Continuous and highly accurate detection of the fill level in tanks

  • Leak monitoring of overflow chambers Liquid leakage monitoring

    Reliable leakage detection with standard capacitive sensors

    The solution

    Spills and leaks of liquids are easily detected with Balluff's line of capacitive sensors using standard capacitive technology. Recently redesigned block style capacitive sensors with integral mounting bracket make detecting leaks easy and simple. Many other housing styles are available that will provide other mounting options to quickly detect minute leaks. These sensors are available with either potentiometer or remote teach capabilities for quick easy setup.

    The features

    • Reliable and industry leading capacitive technology
    • Multiple mounting methods
    • Easy teach and setup to detect the smallest leaks
    Reliable leak monitoring of overflow chambers
