Embodiment
Below in conjunction with accompanying drawing, the utility model is described in more detail.
A kind of compensation vibrating wire sensor with elastic component of the utility model, as shown in Figure 1 and Figure 2: comprise support 2, shell 3, vibration string 4, magnet 5, the two ends of described vibration string 4 are connected with described support 2, the both sides correspondence of described vibration string 4 arranges described magnet 5, magnet 5 is two, produce magnetic field, vibration string is in magnetic field.Described sensor also comprises circuit board 1, is provided with feedback circuit in circuit board, and the two ends of described vibration string 4 are connected with the circuit in described circuit board 1 with the second elastic component 7 respectively by the first elastic component 6.
As shown in Figure 3, described first elastic component 6 comprises the first elastic conductor 8 and the second elastic conductor 9, and described first elastic conductor 8 is isometric and in parallel with the second elastic conductor 9; Described second elastic component 7 comprises the 3rd elastic conductor 10 and the 4th elastic conductor 11, and described 3rd elastic conductor 10 is isometric and in parallel with the 4th elastic conductor 11; Described first elastic conductor 8, second elastic conductor 9, the 3rd elastic conductor 10 and the 4th elastic conductor 11 are all in bending, and length is equal.In prior art, the wire normally vibrated by linearity between string with circuit is connected, and the application's Elastic conductor is bending, thus self has elastic force.When in equipment operation process, produce thermal expansion, vibration string system metal material is made, and preferentially selects aldary, and during installation, vibration string has certain tightening force, and when after vibration string expanded by heating, tightening force will reduce, and elastic component bounces back, and compensates the tightening force reduced.When vibrating string and meeting cold retraction, tightening force will increase, and elastic component opens, thus reduces the tightening force of vibration string.Clamping connection is carried out by insulating blanked clamper string part in the two ends of vibration string, and insulating blanked clamper string part is cylindrical or spherical, is connected in the cell body of support.When the deformational stress vibrating string is greater than holding force, cylindrical or spherical insulating blanked clamper string part can be movable with the junction at vibration string two ends, it is a kind of limited flexible connection, the tightening force of this structure compensation vibration string, avoid the decay vibrating string energy, ensure that the vibration signal of vibration string can transmit by accurate feedback, improve the measuring accuracy of sensor.By elastic component, the tightening force of vibration string can be made to be in stable state, make this sensor measurement stable performance, detect degree of accuracy and improve.
