Problems solved by technology

At present, mainstream acceleration sensor suppliers at home and abroad (such as: B&K, PCB, etc.) do not have acceleration sensors that can be completely immersed in liquids, and some types of acceleration sensors (such as: B&K's 4374, 4375, 4516, 457x type acceleration sensors) Only moderately resistant to liquid splashes

Embodiment Construction

[0012] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0013] Such as Figure 1 to Figure 3 As shown, a fully immersed sensor mainly includes: a panel-mounted circular connector 3, a rubber sealing ring 4, a signal output connector 5, a signal output connector fastening nut 6, an armored shielded signal cable 7, sensor 8

[0014] The inside of the connector 3 is sealed and connected to the signal output joint 5 through the rubber sealing ring 4, the rear part of the signal output joint 5 is locked and connected to the connector 3 through the fastening nut 6, and the signal output joint 5 is connected to the sensor 8 through the armored signal cable 7, And the armored signal cable 7 is welded and fixedly connected to the signal output connector 5 and the sensor 8 .

[0015] The connection between the signal output connector 5 and the connector 3 is sealed by three rubber sealing rings 4 to ensure that the ...

Abstract

The present invention relates to a complete immersion sensor which comprises a sensor installed at the bottom of a container and a connector installed at the side wall of the container. The connector 3 is connected to a signal output joint through rubber sealing rings 4 in a sealed way. The back part of the signal output joint is connected to the connector through a fastening nut in a locked way. The signal output joint is connected to the sensor through an armored signal cable 7, and the armored signal cable and the signal output joint are welded and fixedly connected to the sensor. According to the complete immersion sensor scheme designed by the invention, the use environment of the sensor is expanded further, and the gap of an existing piezoelectric acceleration sensor field is filled.

Description

technical field [0001] The present invention relates to an acceleration sensor, especially a sensor that is permanently and completely immersed in a liquid. Background technique [0002] In some working environments, it is necessary to fully immerse the accelerometer in liquid for a long time or permanently. At present, mainstream acceleration sensor suppliers at home and abroad (such as: B&K, PCB, etc.) do not have acceleration sensors that can be completely immersed in liquids, and some types of acceleration sensors (such as: B&K's 4374, 4375, 4516, 457x type acceleration sensors) Only a certain degree of resistance to liquid splashes is provided. Contents of the invention [0003] The present invention aims to provide a fully immersed liquid acceleration sensor. The acceleration sensor solution can be completely immersed in liquid for a long time or permanently, and has good sealing and insulation properties. [0004] In order to achieve the above object, the technica...
