The PLOP series overpressure test bench utilizes liquids (such as water or oil) as the testing medium and can be custom-configured to meet the specific testing requirements of the instruments under test. Test parameters are set via computer software or a PLC controller; once the target pressure is reached, the system performs overpressure and leak tests. Upon completion of the holding period, the system automatically evaluates the test results. Key features include a high degree of automation, precise and stable output pressure, ease of operation, and reliable performance.
