Explain the function of a pressure sensor in a pneumatic system.

• A. To monitor system pressure and provide feedback to controls for regulation and safety.
• B. To regulate flow rate only
• C. To measure temperature of air
• D. To generate compressed air

Answer: (A)

In pneumatic systems, the pressure sensor provides the essential feedback needed to keep pressure where it should be. It measures the actual air pressure, converts that measurement into an electrical signal, and sends it to the control system. The controller then uses that information to adjust regulators or valves to reach and maintain the desired pressure, and to trigger alarms or safety interlocks if pressure goes outside safe limits. This feedback loop helps prevent both overpressure that could damage components and underpressure that could compromise performance. The other options don’t fit because regulating flow is done by valves or flow controllers, measuring air temperature is a temperature sensor task, and generating compressed air is the job of the compressor.
