How does a technician compute differential pressure associated with a fluid power component?

• A. By adding the pressure of the input and the pressure of the output
• B. By subtracting the pressure at the output from the pressure of the input
• C. By subtracting when the fluid is flowing from the pressure when the fluid is not flowing
• D. By dividing the input pressure from the output pressure

Answer: (B)

Differential pressure is a critical concept in fluid power systems, as it indicates the pressure difference across a component, such as a valve, filter, or pump. To accurately compute this differential pressure, the technician needs to assess two key pressures: the pressure at the input of the component and the pressure at the output. Computing the differential pressure involves subtracting the output pressure from the input pressure. This calculation provides insight into how much pressure is being lost as fluid moves through the component, which can signify how effectively the component is operating. A higher differential pressure may indicate restrictions or blockages, which could necessitate maintenance or replacement of the component. In practical applications, a technician would typically measure the input and output pressures using pressure gauges or sensors and then apply the appropriate subtraction to find the differential pressure. This understanding allows technicians to diagnose issues within fluid power systems effectively.
