What is the role of a pressure gauge in a pneumatic system?

The role of a pressure gauge in a pneumatic system is to measure the pressure of the compressed air. This measurement is crucial because it allows operators to monitor the system's performance and ensure it is functioning within the desired pressure range. Maintaining the correct pressure is essential for the proper operation of pneumatic components, as too high or too low pressure can lead to inefficiencies, potential equipment failure, or safety hazards. By providing real-time pressure readings, a pressure gauge enables timely adjustments to be made, ensuring that the pneumatic system operates effectively and reliably.
