Which component helps to synchronize the hydraulic system?

The correct choice for this question is the hydraulic pressure gauge, which is essential for synchronizing the hydraulic system. A hydraulic pressure gauge, specifically the BAK-12 in this context, measures the pressure within the hydraulic system. This measurement is crucial because it allows operators to monitor the performance and functionality of the hydraulic system in real-time.

When working with hydraulic systems, maintaining the right pressure levels is vital to ensure that all components operate efficiently and effectively. By using a hydraulic pressure gauge, operators can make informed decisions about whether adjustments need to be made to maintain optimal pressure. If the pressures in different parts of the system are not aligned, it could lead to inefficiencies or even mechanical failure.

In contrast, the other components listed, such as pressure regulators, hydraulic accumulators, and fluid reservoirs, while important to the overall operation of a hydraulic system, do not specifically serve the purpose of synchronizing the system. Pressure regulators manage the pressure within the system, accumulators store hydraulic fluid under pressure, and fluid reservoirs hold the hydraulic fluid. None of them provide the direct feedback necessary for synchronization that a pressure gauge does.
