Increase efficiency and reduce emissions

Energy efficiency and emissions reduction are two sides of the same coin: precisely controlled and efficient combustion.

Balluff's magnetostrictive linear position sensors provide precise position feedback on hydraulic actuators for gas supply valves and combustion air damper/regulators and gas turbine governors.

Application examples

  • Process-critical valve control

    Cylinder position sensors with multi-channel redundancy

    The solution

    Quick-action shutoff control valves are subject to stringent control reliability requirements. To ensure the integrity of position measurement signals, sensor redundancy is paramount. Balluff's double- or triple-redundant magnetostrictive linear position sensors provide two or three fully independent, redundant control signals from a single device.

    The features

    • Up to three fully independent position measurement systems in the same housing
    • Variety of popular analog and digital control interfaces
    • Suitable for long stroke valves up to 7620 mm
    • Compact, space-saving housing
    • Non-contact and wear-free for long service life
    • LED status indication for all channels

  • Controlling valves

    With BTL magnetostrictive linear position sensors

    The solution

    Quick acting control valves are subject to the highest requirements that often can only be met by a redundant system. Our BTL 7 magnetostrictive linear position sensor incorporates up to three independent measurement sections and three independent electronic systems in one rod. The robust, contact-free and absolute position measurement system is freely configurable. And: thanks to its compact dimensions, it can easily replace already installed, non-redundant position measuring systems. Startpoints and endpoints can be set comfortably with a computer. And parameter sets are easy to apply, making startup fast and uncomplicated.

    The features

    • 2 or 3 completely separate systems in one housing for maximum availability
    • With a measuring range of up to 7620 mm, it is also suitable for large valves
    • Compact, space-saving housing
    • Fast startup
    • Non-contact and wear-free
    • Monitoring of all channels via LEDs
    Use quick closing check valves

  • Reliable conveyor belt monitoring

    With BOS photoelectric sensors

    The solution

    Our photoelectric sensors with IP69K protection are ideal for withstanding the harsh conditions on the conveyors in a power plant. Protected in their rugged housing, they reliably monitor your conveyor lines. As an option, you can choose an air nozzle to keep the sensor optics from becoming contaminated.

    The features

    • Protection from heat, dust, moisture (IP69 K)
    • Optional air nozzle for cleaning
    • Optional air or water cooling
    • Also available as Ex-version

  • Fast switching operations

    With BML magnetic encoders

    The solution

    When it comes to power switches, it is important to get exact data on the time characteristics of the switching movement: for startup, maintenance work or in-process. Magnetic encoders handle this reliably. This allows you to detect damage early or even prevent it.

    The features

    • For high-dynamic processes
    • Absolute or incremental versions
    • Connection and guide elements available as accessories
    Ensure proper switching actuations
