Autonomous hydraulic compact drive
Autonomous hydraulic compact drive

Energy efficiency and high positioning accuracy

Modern hydraulic compact drives, a union of hydraulics and electronics, are the combination of intelligence and power. This reduces installation and maintenance costs. And saves up to 80 % energy consumption by the axes.

The compact drive consists of a closed fluid circuit with cylinder, pump, control block and accumulator as well as the servomotor for the pump, the control unit with interface, and the sensors for monitoring pressure, temperature and travel.

For integration in the closed fluid circuit of the compact drive, Balluff offers linear position sensors for reliable feedback to ensure high positioning accuracy. Also, Balluff offers compact intelligent sensors for pressure and temperature measurement. These report actual operating conditions and enable predictive maintenance. The data interfaces built into the drive – fieldbus, Ethernet, OPCUA or IO-Link – are used by the autonomous axis to communicate with the machine controller or directly to the cloud.

Application examples

  • Cylinder feedback for compact drives

    With BTL magnetostrictive linear position sensors

    Very small sensors are needed in compact cylinders. The BTL K compact magnetostrictive linear position sensor meets this requirement ideally. Its short housing of just 34 mm in length saves valuable space in and around the cylinder. The stainless steel housing with plug-in flange and rugged hex screw fastening means you will not need an additional protective housing.

    Features

    • Easy characteristic curve setting
    • IP67/68, shock and vibration proof
    • Optional pressure-rated housing, suitable for offshore
    • With analog signals, digital interfaces, fieldbuses or Ethernet

  • Monitor pressure in the complete drive system

    With BSP pressure sensors

    With our pressure sensors you monitor the pressure in the entire drive system. And benefit from easy handling and high accuracy. The large display and simple operating concept per VDMA means it is simple and quick to configure. At the same time the current system pressure is shown on the bright LED display. Since the display and electrical output can be turned into a position independent of the flange, Balluff pressure sensors can be installed flexibly while saving space.

    Features

    • Binary switching outputs or analog output signals
    • With IO-Link for thorough diagnostics
    • Available up to –40 °C for handling demanding environments
    Monitor pressure in the complete drive system

  • Continuously monitor oil temperature

    With BFT temperature sensors

    Media contacting temperature sensors allow the hydraulic fluid temperature to be reliably monitored in the hydraulic power unit. Since this takes place within the hydraulic circuit, our sensors ensure the proper viscosity of the fluid and thereby the performance capability of your machine.

    Critical process conditions such as a temperature limit can be controlled directly via the switching output. An analog output provides continuous measurement results. This assists with process stability.

    Features

    • M12 connector for simple installation
    • With rotating, easy to read display: flexible installation and operating convenience
    • Compact form factor and high resistance to vibration
    Continuously monitor oil temperature
