What role do sensors play in pneumatic systems?

Sensors play a critical role in pneumatic systems by monitoring various conditions such as pressure, temperature, and flow rates. They provide vital feedback to the control systems, allowing for real-time adjustments and improvements in system performance. By continuously collecting data about operating parameters, sensors enable operators to ensure that the system is functioning efficiently and safely. This monitoring capability is essential for optimizing performance, preventing malfunctions, and maintaining system reliability.

In contrast, other options do not accurately describe the function of sensors. Increasing air pressure and producing compressed air are tasks associated with compressors and regulators, not sensors. Reducing mechanical wear involves design features and materials used within the system rather than the function of sensors, which are primarily concerned with monitoring and providing information.
