| Abstract: |
| Objective To improve the qualified rate of pressure switch in low pressure test. Methods Low pressure test methods of pressure switches to be used to tethered balloons were researched. Defects of traditional low pressure test methods were analyzed and a new low pressure test method was proposed. Contrast test on two test methods were carried out. Results The pass rate of pressure switches was 40% when the test was carried according to the traditional method. The new low pressure test method could improve the pass rate of pressure switches significantly. Conclusion The new low pressure test method can improve the pass rate of pressure switches and reflect actual conditions of pressure switches more objectively. |
