What is the signal range for pneumatics?

The appropriate signal range for pneumatics is typically understood to be 3-15 psi. This range is commonly used in control systems for pneumatic actuators and instrumentation. The lower limit of 3 psi serves as a baseline to ensure that there is a measurable pressure to indicate a "zero" or "off" status in a control scenario. The upper limit of 15 psi allows for adequate actuation force and response in pneumatic devices, providing a standard range for various applications in industrial settings.

This signal range allows for effective control of pneumatic systems, facilitating the smooth operation of valves, cylinders, and other pneumatic components. The design of control systems often utilizes this specific range because it aligns well with the characteristics of pneumatic components, ensuring reliable and consistent performance across various industrial applications.
