| Abstract: |
| A new developed computer system for data acquisition and analysis used in hydraulic relief valve performance test is introduced. This system can be used for the dynamic experiments of relief valve pressure response in flow step change, relieving load, establishing pressure characteristics and data acquisition. In addition, it can be used for the calibration of pressure trasducer, data inquiring and copy, as well as the analysis, display and printing of the results. |
