Pneumatic signals operate within which pressure range?

Pneumatic signals are typically used in various control systems and instrumentation, relying on compressed air or gas to transmit signals or control actions. The standard operational pressure range for pneumatic systems generally falls between 20 to 100 kPa. This range is optimal because it allows for effective signal transmission with adequate responsiveness while also ensuring safety and reliability in operations.

Operating within this pressure range helps to minimize the risk of leakage and maintain a clear and stable signal for control processes. Higher pressure levels might introduce complications, such as noise or malfunctioning components, which is why 20 to 100 kPa is the most widely adopted standard for pneumatic signaling. Equipment designed for pneumatic control is often calibrated within this range to ensure optimal performance and responsiveness.
