Reliable at high temperatures, with shocks and vibrations

Steel is produced under the most difficult conditions - at high temperatures, as well as with shocks and vibrations. On the one hand, this requires a reliable process with the best possible quality management, on the other hand it requires top quality systems. We offer you optimal, internationally approved sensors, as well as corresponding network and connection technology.

Application examples

  • Positioning the rollers

    Precise coil winding

    The solution

    Our BTL magnetostrictive linear position sensors wind up the metal coils with high precision. They guide the pressure roller as a function of the roll diameter for optimum steel strip bundles.

    The features

    • Absolute output signal
    • Extremely exact for precisely guiding pressure rollers
    • Also with IO-Link for easy wiring
    Positioning the rollers

  • Setting the roll gap

    Outstanding accuracy during hot or cold rolling

    The solution

    Our BTL magnetostrictive linear position sensor in IP69K ensures precise operation during hot or cold rolling: The linear position sensor maintains the set roll gap with high accuracy. It is vacuum-sealed and does not require any additional protection even when there is continuous water cooling of the rolling stand.

    The features

    • Outstanding accuracy for precise work
    • Stainless steel housing for tough applications
    • Vacuum sealed, even during constant water cooling

  • Controlling the slab guidance

    Precise positioning of slabs in rollers

    The solution

    Our BTL magnetostrictive linear position sensors in the hydraulic cylinder guide and position the slabs with precision. They check for the correct configuration of the lateral guides and accompany the slabs on their path through the rolling stand. In addition, the system safely compensates for the strong forces that occur during reshaping.

    The features

    • Rapid Replacement Module (RRM) for fast changes without interrupting the hydraulic circuit
    • Vibration and shock resistant

  • Monitoring ladle movements

    Reliable and safe casting process

    The solution

    Optimum control over the steel casting process and ensuring the addition of the correct amount of steel to the continuous casting line is only possible through precise casting ladle movements. Our BTL7 magnetostrictive linear position sensors (double and triple-redundant) provide absolute security and the best reliability for your continuous casting process.

    The features

    • Redundancy for absolute security
    • The highest availability through completely independent systems in one head
    • Easy to retrofit, since it is compatible with the standard BTL

  • Controlling the air and gas supply in blast furnaces

    Reliable control of the valves and flaps at the blast furnace

    The solution

    Our BTL magnetostrictive linear position sensors regulate the supply and return air in pig iron production by controlling valves and flaps at the blast furnace. In addition, a temperature sensor is integrated into the electronics head that correctly measures the system temperature, thereby increasing the safety of your system.

    The features

    • Temperature measurement integrated in the position measurement system
    • Explosion protection versions
    • Non-contact operating principle

  • Controlling coke oven movements

    Reliable control at high temperatures

    The solution

    Extremely high temperatures are not a problem for our BTL magnetostrictive linear position sensor integrated in the hydraulic cylinder: The system controls all movements of the coking plant machines up to 100 °C. The robust metal housing with IP67 and PTFE cables even permits the linear position sensor to be used at temperatures of up to 200 °C.

    The features

    • High-temperature resistant for use on the coke oven battery
    • Metal housing with IP67
    • Different interfaces
