What hydraulic range is specified for pressure instrument testing?

• A. 0 to 150 PSI
• B. 150 PSI to 6000 PSI
• C. 28.5" Hg to 1000 PSI
• D. 300 PSI to 6000 PSI

Answer: (B)

The specified hydraulic range for pressure instrument testing is significant because it encompasses the pressures that pressure instruments are designed to handle effectively during calibration and verification processes. The range of 150 PSI to 6000 PSI indicates a broad spectrum suitable for a wide variety of applications in various industrial and laboratory settings. This range allows calibration technicians to test instruments that are used in both low-pressure environments, such as certain laboratory conditions or specific industrial processes, and high-pressure applications, which can be found in oil and gas, manufacturing, and other sectors that utilize hydraulic systems. In contrast, the other options are limited in their applicability. The first option, covering 0 to 150 PSI, does not meet the requirements for many high-pressure applications. The third option, which spans from 28.5" Hg (a measurement of vacuum) to 1000 PSI, includes a vacuum measurement that may not be relevant for standard pressure instrument testing. The fourth option, ranging from 300 PSI to 6000 PSI, while closer to the correct range, ultimately does not encompass the full range of lower pressures that many instruments may need for calibration. Therefore, the choice of 150 PSI to 6000 PSI is comprehensive, adequately addressing both lower and upper limits essential for
