Problems solved by technology
[0002] Due to structural reasons, the current dual-axis inclination sensor has relatively low measurement accuracy. If you need to measure relatively high accuracy, you need to use two single-axis high-precision sensors to replace it. If two single-axis inclination sensors are used, the cost It will increase, the supporting circuit will become complicated, and the installation is more troublesome, especially the installation of two sensors that need to be orthogonal to 90 degrees cannot be guaranteed

The invention discloses a high-precision dual-axis tilt sensor. The high-precision dual-axis tilt sensor comprises a base and a top cover covering the base, and further comprises four L-shaped electrodes; the base is internally provided with a cross-shaped convex-concave groove structure; an arch-shaped structure matched with the cross-shaped convex-concave groove structure and provided with a crossbeam with a radian is arranged in the top cover, so that the position between the cross-shaped convex-concave groove structure and the arch-shaped structure with the crossbeam with the radian is provided with a cavity capable of containing the electrodes and an electrolyte; the middle of the cross-shaped convex-concave groove structure of the base is provided with an electrolyte injecting hole penetrating through the base; a sealing plug is arranged at the electrolyte injecting hole; each corner of the cross-shaped convex-concave groove structure is provided with an electrode mounting hole penetrating through the base; and each L-shaped electrode is composed of a detection end and a signal output end. The high-precision dual-axis tilt sensor has the advantages that the top cover is designed to be of the arch-shaped structure with the orthogonal crossbeam with the radian, so that the two axial directions are ensured to be perpendicular to each other, and therefore the accuracy of dual-axis measurement of the tilt sensor is ensured.
Description
technical field [0001] The invention relates to an inclination sensor, in particular to a high-precision dual-axis inclination sensor. Background technique [0002] The current dual-axis inclination sensor has relatively low measurement accuracy due to structural reasons. If you need to measure relatively high accuracy, you need to replace it with two single-axis high-precision sensors, and if you use two single-axis inclination sensors, the cost It will increase, the supporting circuit will become complicated, and the installation is more troublesome, especially the installation of two sensors that need to be orthogonal to 90 degrees cannot be guaranteed. Contents of the invention [0003] The technical problem solved by the invention is to provide a high-precision dual-axis inclination sensor that solves the problem of orthogonal 90 degrees. [0004] The technical solution adopted by the present invention to solve the technical problem is: a high-precision dual-axis inc...
