| Abstract: | The mechansim of parallel connection mesurement is presented. Parallel sensors are chozen as the measurement method in liquid propellant rocket engine tests. Multiple sensors connections are analyzed and tested. The analysis and test results show that parallel connection measurement of thrust sensors can improve the measurement precision and eccentric load has little effect on the result. |
