Abstract
The utility model relates to a piezo-electric full-orientation vibration sensor, belonging to a sensing element. An elastomer is welded on a piezo-electric piece, a mass block is arranged on the elastomer, and the piezo-electric piece is arranged on a housing. The utility model has the advantages of simple structure, high sensitivity, small size, light weight and great electrical signal output, and is capable of measuring full-orientation vibrations.
Description
The utility model is the comprehensive vibration transducer of a kind of piezoelectric type, belongs to sensing element.
At present, this kind sensor can be divided into two classes, and a class is that piezoelectrics directly contact with mass, can only survey vertical vibration, and another kind of is that piezoelectrics are made cantilevered, can only measure the vibration of single direction, multi-directionly must adopt a plurality of piezoelectrics if survey.
It is low that the purpose of this utility model provides a kind of cost, and make its vibration signal be directly changed into electric signal, do not need adjunct circuit, simple in structure, highly sensitive, can survey the sensor of comprehensive vibration.
The utility model is realized with following technical scheme: elastic body is welded on the piezoelectric patches, and mass is contained on the elastic body.Be connected to lead on the piezoelectric patches, piezoelectric patches is contained on the shell.
The utlity model has simple in structure, highly sensitive, volume is little, the output of light weight, electric signal is big, adopts a piezoelectric patches, just can measure the characteristics of comprehensive vibration.
Now in conjunction with the accompanying drawings the utility model is described in further detail.
Fig. 1 is that the utility model master looks cut-open view.
Fig. 1 is the utility model specific embodiment.Elastic body 3 is welded on the piezoelectric patches 4, and mass 2 is contained on the elastic body 3.Piezoelectric patches 4 is contained on the shell 1.Be connected to lead 5 on the piezoelectric patches 4.
Claims (1)
1, the comprehensive vibration transducer of a kind of piezoelectric type is characterized in that elastic body 3 is welded on the piezoelectric patches 4, and mass 2 is contained on the elastic body 3, and piezoelectric patches 4 is contained on the shell 1, is connected to lead 5 on the piezoelectric patches 4.
