Embodiment Construction

[0023] Such as figure 1 Shown is a schematic structural view of the pressure sensor protection device of the present invention. The structure of the pressure sensor protection device includes a housing shell 1 and a fixedly connected cover plate 3 at its opening. The housing shell 1 is a hollow cylindrical structure for accommodating the pressure sensor 5 . The inner diameter of the housing shell 1 is greater than the outer diameter of the pressure sensor 5 , so that a gap is formed between the inner surface of the housing shell 1 and the pressure sensor 5 . The gap is selected according to the material of the housing shell 1 and the type and size of the mechanical disturbance. The gap is generally greater than 0.1 mm. The shell shell 1 can be fixedly connected to the cover plate 3 by screwing, or can be fixedly connected by other methods. The material of the housing shell 1 can be replaced according to the requirements of complex environments.

Abstract

The invention discloses a pressure sensor protection device. The pressure sensor protection device comprises a shell body and a cover plate fixedly connected to an opening of the shell body. The shell body is of a hollow cylindrical structure and used for containing a pressure sensor. The invention further discloses an assembly method of the pressure sensor protection device. Due to the interval between the pressure sensor and the shell body and the interval between the pressure sensor and an axial translational motion plate, influences on the measurement precision of the sensor caused by long-term or instantaneous mechanical disturbance are avoided, and influences on the pressure sensor caused by external temperature changes are delayed. The pressure sensor protection device overcomes the defect that an existing pressure sensor is prone to external mechanical disturbance and can be used in measurement work of air pressure and liquid pressure in complex load environments.

Description

technical field [0001] The invention relates to the field of pressure sensors, in particular to a pressure sensor protection device and an assembly method thereof, which can eliminate the influence of mechanical disturbance on the pressure sensor. Background technique [0002] The pressure sensor is a detection device that can sense the measured information, and can convert the detected information into an electrical signal or an information output in the required form according to a certain rule, so as to meet the requirements of information transmission, processing, and storage. , display, recording and control requirements. [0003] At present, there are various types of pressure sensors, and their application range is relatively wide. However, due to the complexity of the use environment, it has defects. The traditional sensor protection device only weakens the mechanical disturbance by thickening the shell size, but under the long-term mechanical or environmental dist...
