Filter noise to improve machine productivity 3

To improve the productivity of machines, designers and integrators look for ways to make them run smoother. But often real-world conditions pose problems along the way. For example, sensor feedback signals can be noisy, or the valves that are selected could pose a problem, making precise hydraulic control difficult. When the real world doesn’t “behave” smoothly, what do you do?

Working Under Pressure: Using a Motion Controller for Pressure Control

Closed-loop control methods control pressure more accurately than pressure relief valves or pressure regulators.

Closed-Loop Control Simplifies Cyclical Testing

Figure 1. Hydraulic leaf spring tester controls both position and force being exerted by the actuator. Fluid power often is the first choice whenever a predictable amount of force must be exerted, ...

Rotary encoders are good for your system

When working with high precision rotating machinery, like that in the lumber industry, encoders can make your life much easier.

The truth about problem valves

Choose and use your valves wisely to achieve precise control.

Accumulators: The unsung heroes of hydraulic motion control

Accumulators can conserve energy, make systems easier to control, and extend a machine's useful life, making them especially important for electrohydraulic motion control systems
