The structure and basic theory of automatic inclinometer system was presented, which take advanced quartz servo-accelerometer as sense organ. Quartz inclinometer can be used to measure the vertical vector of gravitation g in axes using probe sensor in order to confirm the incline angle of probe axes relatively horizontal. Therefore uprightness displacement of probe axes relatively horizontal can be calculated based on this measuer principle. The paper presents the real-time measuring curve of quartz inclinometer. The result indicates that the system has many merits, such as high measure precision, better anti-jamming character, light mass, low power cost and it fits fieldwork for power supply by battery.
