The invention relates to the field of horizontal attitude sensors, in particular to a horizontal attitude sensor using a quartz force sensitive resonator as a sensitive component. The horizontal attitude sensor comprises the sensitive component, a circuit board, a sensitive mass block, a base, a tray, an overload protecting frame, a seat and a housing, wherein the sensitive component is composed of two pieces of six-electrode quartz sensitive components, the two six-electrode quartz sensitive components are parallely arranged in front and back, the bottoms of the two six-electrode quartz sensitive components are fixedly connected with the base, and the tops are fixedly connected with the sensitive mass block. According to the corresponding six-electrode quartz sensitive component, each sensitive component can obtain 15 difference-frequency signals through combination, the difference-frequency signals are accumulated and summed, and the obtained force frequency conversion coefficient can reach the scale of n*103 Hz / N. The two sensitive components operate simultaneously, and if the difference-frequency signals of the two sensitive components are accumulated one more time, the ultimate force frequency conversion coefficient can reach the scale of 2n*103 Hz / N.
Description
technical field [0001] The invention relates to the field of horizontal attitude sensors, in particular to a horizontal attitude sensor using a quartz force sensitive resonator as a sensitive element. Background technique [0002] The existing quartz attitude sensors usually use two independent single-substrate single-electrode quartz resonators with basically the same temperature characteristics to eliminate the interference of factors such as temperature in the form of difference frequency. However, due to the different crystal substrates of the two independent resonators (chips are taken from different positions, differences in processing technology, local defects, etc.), the interference of temperature characteristics and other material factors in the difference frequency signal obtained by difference frequency processing is still Existence, these interference factors have become the bottleneck problem of this kind of sensor in the field of high precision application, ne...
