What is the main purpose of a pressure gauge in a hydraulic system?

The primary function of a pressure gauge in a hydraulic system is to measure the pressure of hydraulic fluid. This measurement is crucial for several reasons, as it allows operators to monitor system performance and ensure that the pressure levels remain within safe and optimal ranges. If the pressure is too high, it could indicate a potential hazard; conversely, if it’s too low, it might signify issues with the hydraulic components that could lead to system failure or inefficiency.

In the context of hydraulic systems, consistent pressure readings help in diagnosing problems, maintaining system efficiency, and guiding maintenance activities. By providing this essential pressure information, the gauge ensures proper operation of hydraulic machinery and contributes to overall safety and reliability within the system.
