Whether standard pneumatics is sufficient or a controlled solution makes sense depends on the actual process requirements. This guide outlines which selection criteria are key and when a deeper review of Controlled Pneumatics is worthwhile.

Standard pneumatics is suitable for simple, stable applications with clear end positions and consistent conditions.

1. Simple switching and motion tasks

Standard pneumatics is usually suitable in cases where when defined end positions suffice, pressure remains constant, no ongoing adjustment is required and processes are simple and repeatable.

2. Stable process conditions

Fixed settings are often sufficient for consistent workpieces, low load fluctuations, stable environmental conditions, large tolerances and infrequent product changes.

3. Moderate precision requirements

What matters is not the maximum possible accuracy, but the permissible deviation within the process.

4. When standard pneumatics is the better choice

Standard pneumatics is suitable when simple, stable functions are more important than continuous control, process data or the highest control quality.

Controlled Pneumatics becomes relevant when process variables not only need to be set, but also actively controlled during operation. The application is crucial, not the technology.

1. High requirements for precision and repeatability

A controlled solution is useful when tight tolerances, reproducible results and stable quality are required despite changing conditions. The required process accuracy is decisive.

2. Changing loads and disturbance variables

Controlled Pneumatics can actively compensate for deviations when process conditions change during operation. This applies, for example, to different workpieces, fluctuating material properties, varying loads or external influences such as changes in pressure and friction. Despite these variations, closed-loop control ensures that the desired process variables remain stable and consistent results are achieved.

3. Variable products and frequent changeovers

With frequent product changes, digitally adjustable parameters can reduce manual adjustments and errors. In this way, setup times can be reduced and processes can adapt more quickly to new requirements. The benefit strongly depends on the frequency of change and the current effort.

4. Continuous control requirements

A controlled solution is relevant when process parameters vary, intermediate values are required, or deviations need to be corrected automatically. The key question is: Is fixed open-loop control sufficient, or does the process have to respond?

5. Process data for more transparency

The available process data creates transparency and provides insights into the health status of applications and machines. Closed-loop control systems thereby support diagnostics, documentation and quality assurance. They are useful when process values and machine or system states need to be traceable, deviations should be identified early, or real process values are incorporated into the controller. True added value is created only when this data is actively analyzed and purposefully utilized.

Before a selection is made, the parameter that defines the process must be clear. Controlled Pneumatics can control pressure, flow rate or movement.

Pressure

Relevant when the pressure directly affects the force or quality. It is important to clarify the working range, permissible deviation, response time and potential disturbances.

Flow rate

Determines speed and supply. The volume flow rate, setpoint behavior, fluctuations and dynamics need to be clarified.

Movement

It is crucial to determine whether only end positions are relevant or whether intermediate values are as well. Examples include variable speeds, intermediate positions, different motion profiles or changing loads.

Standard pneumatics is ideal for stable, simple applications with clear conditions. Controlled Pneumatics becomes relevant when processes vary, need to be precisely controlled or have to adapt dynamically. The decision does not depend on the technology, but on how strongly and precisely the process needs to respond to changes.
