Linear Feedback Hydraulic Cylinders
Linear feedback devices can be internally or externally mounted to provide precise hydraulic cylinder positioning. Our customers use these cylinders for accurate positioning and velocity control of their system.
These hydraulic cylinders with linear feedback are custom designed to meet the specific requirements of our customers’ applications.
These cylinders include electro-hydraulic, SMART, and linear position (LVDT). HDM offers numerous communication protocols including CANopen and Safety SIL2. They are ideal for applications in agricultural spraying and cultivation equipment; motion control; cut-to-length operations for manufacturing aluminum, steel, and non-metallic materials; aviation deicing; and more.
Linear feedback hydraulic cylinders are specialized hydraulic actuators that integrate position feedback sensors, typically linear position transducers, within the cylinder itself. These sensors provide real-time data on the piston rod’s position, allowing for precise control of movement and positioning. The feedback loop enables the system to adjust hydraulic pressure and flow automatically to achieve the desired movement or force, even compensating for variations in load or speed.
Linear feedback cylinders enhance accuracy, repeatability, and efficiency in processes like material handling, machine tool positioning, and large-scale construction operations. Additionally, they help reduce downtime and maintenance needs by providing diagnostic information that can indicate issues before they cause failure.
