What role does a pressure gauge serve in hydraulic operations?

A pressure gauge plays a crucial role in hydraulic operations by providing information about hydraulic fluid pressure. This information is vital for several reasons: it ensures that the system is operating within the desired pressure range, which is critical for the efficient functioning of hydraulic components. Monitoring pressure helps to prevent both under-pressure and over-pressure situations, thus protecting the components from potential damage and ensuring safe operation.

Additionally, knowing the hydraulic fluid pressure allows operators to assess the performance of the hydraulic system and make necessary adjustments or maintenance decisions. These measurements can indicate if there is a leak in the system or if the pump is functioning properly, contributing to overall system diagnostics and performance evaluations.
