Description
Technical field
The utility model is related to electronics industry fields, more particularly, to a kind of piezoelectric type IEPE pressure sensings of simplified test
Device.
Background technology
Original charge sensor test method be from sensor to charge amplifier, then arrive data collector, centre needs
The low noise shielded cable of connect band graphene is wanted, the cable cost is high, and use cost is high, and cable is during signal exports
The interference being subject to directly affects data collection effect, can not achieve long distance transmission；Centre connection charge amplifier use at
This height, volume is big, needs additionally to power.
Invention content
The utility model aims to solve the problem that drawbacks described above, provides a kind of piezoelectric type IEPE of simplified test.
In order to overcome defect present in background technology, the utility model to solve technical solution used by its technical problem
It is：A kind of piezoelectric type IEPE pressure sensors of simplified test, including ontology, the bottom end of the ontology are equipped with diaphragm, described
Compensating plate, first crystal piece, conductive sheet and the second crystal wafer are equipped between body and diaphragm successively, is hollow structure in ontology, it is hollow
Impedance converter unit is equipped in structure, impedance converter unit one end connects jack by conducting wire, and one end connects conductive by conducting wire
Piece is equipped with lining core between jack and ontology.
In a preferred embodiment of the utility model, between diaphragm and first crystal piece, conductive sheet and the second crystal wafer
Equipped with bushing.
The utility model has the beneficial effects that：It is defeated that the high impedance charge signal of sensor is become voltage signal in low impedance
Go out, without by special mininoise cable and and charge amplifier, it is only necessary to common shielded cable and it is suitable adjust device, it is long away from
It will not be influenced by noise distortion when from transmission, achieve the effect that low cost long distance transmits.Charge amplifier and sensor one
The setting of body simplifies intermediate link, saves cost so that means of testing more high-efficient simple.
Description of the drawings
The utility model is further illustrated with reference to the accompanying drawings and examples.
Fig. 1 is the structural schematic diagram of the utility model.
Specific implementation mode
The preferred embodiment of the utility model is described in detail below in conjunction with the accompanying drawings, so that the advantages of the utility model
It can be easier to be readily appreciated by one skilled in the art with feature, it is apparent clear to be made to the scope of protection of the utility model
Define.
A kind of piezoelectric type IEPE pressure sensors of simplified test as shown in Figure 1, including ontology 1, the bottom end of ontology 1 are equipped with
Diaphragm 2 is equipped with compensating plate 3, first crystal piece 4, conductive sheet 5 and the second crystal wafer 6, the ontology successively between ontology 1 and diaphragm 2
It is hollow structure in 1, impedance converter unit 7 is equipped in hollow structure, impedance converter unit one end connects jack 8 by conducting wire,
One end connects conductive sheet 5 by conducting wire, and lining core 9 is equipped between jack 8 and ontology 1.Diaphragm 2 and first crystal piece 4, conductive sheet 5 and
Bushing 10 is equipped between second crystal wafer 6.
The high impedance charge signal of sensor is become voltage signal in low impedance output, without passing through special low noise acoustic-electric
Cable and and charge amplifier, it is only necessary to common shielded cable and it is suitable adjust device, will not be by noise distortion in long distance transmission
It influences, achievees the effect that low cost long distance transmits.Charge amplifier and the integrated setting of sensor, simplify intermediate ring
Section saves cost so that means of testing more high-efficient simple.
