Reliable position feedback offers security

When high reliability and precision are demanded, hydraulic drives with integrated magnetostrictive linear position sensors are the first choice. Directly installed in the pressure area of the hydraulic cylinder, this system ensures precise actual value detection of the piston position.

The various interfaces allow you to select the system that is right for your application. And stroke lengths of from 25 to 7500 mm cover every possibility.

Our intelligent magnetic field positioning system is suitable for all non-magnetic cylinder types. This absolute positioning system continuously and highly accurately detects the current piston position through the cylinder wall. And it is easy to install, with no slot types to take into consideration.

Application examples

  • Measure positions in industrial hydraulics

    With BTL magnetostrictive linear position sensors

    Magnetostrictive linear position sensors from Balluff have become the standard for reliable, high-precision position measurement in industrial hydraulics. Their pressure rating of up to 1000 bar matches that of the hydraulic cylinder. The non-contact operating principle guarantees freedom from wear and virtually unlimited life expectancy. Our absolute systems also require no homing move. Their precise output signal is presented as an absolute signal when starting up.

    Features

    • Pressure rated to 1000 bar – expanded range of application
    • Analog, digital, fieldbus or Ethernet interfaces
    • Measuring lengths of up to 7620 mm
    • High shock and vibration resistance

  • Detect two positions at the same time in double piston drives

    With BTL magnetostrictive linear position sensors

    Do you need to detect two position with one system in a double piston drive? Now you can with the magnetostrictive linear position sensors from Balluff. The second piston position is detected with a magnet through the non-magnetic piston rod of Piston 1. In joining and fastening technology, for example, nothing more stands in the way of correct and precise clinching, riveting or crimping.

    Features

    • One system for two strokes, highly economical
    • Compact design, saves space
    Detect two positions

  • Detect position in mobile hydraulics

    With BTL magnetostrictive linear position sensors

    Sensors can be used to significantly extend the service life of mobile machinery. You can also use sensors to increase their safety. The BTL AR position sensor reliably detects the piston position on mobile hydraulic cylinders. The compact form factor of the sensor makes it ideal for use in narrow spherical bearings and swivel eye cylinders as well as in larger diameter cylinders.

    Features

    • EMC approvals enable interference-free use
    • E1 certified for mobile applications
    • Small housing for perfect integration
    • With clever click-plug system for simple installation

  • Piston position measured through block cylinder wall

    With BMP magnetic field positioning systems

    With the non-contact and wear-free BMP magnetic field positioning system you can turn your non-magnetic block cylinder into an IIoT-capable drive system.

    This absolute positioning system continuously and highly accurately detects the current piston position through the cylinder wall. And with IO-Link it opens up additional parameterization and diagnostic possibilities. In addition to the process data, you also obtain information about device status, operating temperature and current ambient conditions.

    Features

    • Flexibility with modular concept: for a variety of cylinders over a total stroke of from 32 to 256 mm
    • Ready for Industry 4.0: Condition monitoring and predictive maintenance
    • Easy installation
