Embodiment Construction

[0027] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0028] Such as Figure 1 to Figure 8 As shown in , the inclination sensor of the present invention includes an electrode 1 and a housing 3 with a cavity 2 structure, an electrolyte 9 is injected into the cavity 2, and an electrode penetrating through the housing 3 is provided on the housing 3 hole 4, the electrode 1 is inserted into the electrode hole 4, and one end of the electrode 1 goes deep into the cavity 2, and the other end of the electrode is located outside the casing 3, and the material of the casing 3 is ceramic material.

[0029] In the present invention, the casing 3 made of ceramic material is used instead of conventional glass material, thus solving the problems existing when using the casing made of glass material. In addition, due to the use of ceramic materials, the sealing operation of the shell in the later stage is very in...

Abstract

The invention provides a tilt angle sensor and belongs to the technical field of sensors. The tilt angle sensor comprises an electrode and a shell with a cavity structure, wherein an electrolyte is injected into the cavity; an electrode hole running through the shell is formed in the shell; an electrode is inserted into the electrode hole; one end of the electrode is inserted deep into the cavity while the other end of the electrode is located in the shell; a ceramic material is taken as the material of the shell. According to the invention, the shell is made from the ceramic material, the strength of the shell made from the ceramic material is higher, pressing injection molding can be applied and the design and processing of the tilt angle sensor are more convenient. Besides, the surface property and the processing property of the shell made from the ceramic material are greatly better than those of the shell made from glass material, so that the tilt angle sensor with more excellent performance, higher reliability, diverse structure and wider application scope can be manufactured.

Description

technical field [0001] The invention belongs to the field of sensors, in particular to an inclination sensor. Background technique [0002] The inclination sensor is a measuring device used to measure the inclination angle. It usually includes a housing with a cavity inside the housing. At the same time, a certain amount of electrolyte is injected into the cavity; For the electrodes, when the liquid in the casing is tilted, the electrical signal on each electrode will change, and then, by measuring the change of the electrical signal, the tilt angle at this time can be known. [0003] However, in the existing inclination sensors, the housing part is usually made of glass. The main reason is that the housing needs to be sealed during processing, so the housing made of glass is easy to perform the sealing operation. However, since the housing is made of glass, there are the following problems: [0004] A. The machinability of the glass shell is poor; [0005] B. The surface...
