Measuring speed
Measuring speed

Our sensors detect speed when integrated in the drive or indirectly. Balluff sensor technology precisely measures the speed of gears and shafts regardless of the diameter – even at high and low speeds.

Application examples

  • Monitor rotor speed

    We reliably protect your wind turbines against overspeeds

    The solution

    Our BES inductive sensors measure the rotor speed in your wind power plants. Extremely reliable, even at temperatures up to –40 °C. Two inductive sensors aimed at the locking plate are sufficient for measuring the speed and detecting the direction of rotation of the rotor. Balluff thereby reliably protects your plant from overspeed.

    The features

    • High switching distance
    • Extended temperature range
    • Contactless detection
    • Insensitive to contamination
    Energy, wind power, monitoring rotor speed

  • Speed measurement

    Extremely accurate measurement of speed and detection of direction of rotation and lock position

    The solution

    Our BML magnetic encoder measures the speed of your rotors with extreme accuracy, even at low speeds. The magnetic tape measurement system is simply attached to the main shaft. This allows it to not only detects the direction of rotation, but also the correct position for the rotor lock using reference points. It does all this without contact and therefore without causing wear.

    The features

    • Extremely accurate, even at very low speeds
    • Wear and maintenance-free thanks to contact-free working
    • Approach of positions possible

  • Monitor generator speed

    Ensure optimum control quality for feed-in

    The solution

    Generator speed is an important parameter for controlling your plant. The Balluff BML magnetic encoder reads the pole on the magnetic ring without contact, thereby monitoring the generator speed extremely reliably. Our sensors can also be used on shafts with a large diameter, e.g. due to a variety of ring diameters or as tape solutions. Through maximum durability and precision, we guarantee you optimum control quality for feed-in.

    The features

    • Simple, space-saving installation
    • Maximum service life thanks to contact-free operation
    • High precision thanks to high resolution

  • Custom tailored feedback solutions for linear and rotary drives

    Custom tailored feedback solutions for linear and rotary drives

    The solution

    Magnetic distance and angle measurement systems are ideal for direct integration in linear and rotary drives. This is because they offer you a wide range of magnetic tapes which can be adapted to many different requirements. If standard versions don't fit your application, we can develop application-specific processing electronics for you or integrate a suitable circuit into the existing electronics design.

    The features

    • Can be directly integrated
    • Wide range of magnetic tapes

  • Absolute motor feedback in real time

    Absolute motor feedback in real time

    The solution

    With the compact version of the absolute encoder disc, a simple to integrate, highly precise absolute feedback solution is possible for detecting the actual position of motors and drives. The encoder disc system offers you a first-class alternative to traditional magnetic, inductive or optical solutions.

    The features

    • No time consuming reference point moves thanks to the absolute measuring system
    • Rapid startup: Generous distance between sensor and code disc
    • Insensitive to run-out tolerances, short installation times
    Absolute motor feedback in real time

  • Measure slow and fast speeds

    Measure slow and fast speeds

    The solution

    Magnetic encoders are also extremely precise at very slow speeds. They detect both the direction of rotation and the correct shaft position using reference points without contact and wear-free.

    The features

    • High system security: wide speed range
    • Fast commissioning using reference points
