Abstract

The utility model provides a kind of signal transducer for having and shaking blanking function, including current impulse generation device, signal transducer, magnet, waveguide wire, the electric current line of return and spring blanker, the output signal that the current impulse generation device is produced is transmitted by the waveguide wire of connection, the waveguide wire through signal transducer center after connecting spring blanker, the spring blanker connects the electric current line of return, and the magnet is arranged on the side of waveguide wire.The utility model has the advantage that：By increasing spring blanker, useless micro- twisting signal absorption of generation is finally eliminated, each measurement period of signal transducer is only detected an electric impulse signal, simplifies the post-processing difficulty of signal, it is ensured that the output of measurement result is stable.

Description

Signal transducer with vibrations blanking function

Technical field

The utility model belongs to signal transducer technical field, more particularly, to a kind of signal for having and shaking blanking function Sensor.

Background technology

In magnetostriction principle, the current impulse produced by current impulse generation device is passed by waveguide wire and the line of return Defeated, the small twisting signal that the fixed magnetic field and current impulse magnetic field interaction that magnet is produced are produced by Wertheim effect is to two Individual direction transmission, transmits and passes through signal transducer being converted to electric impulse signal 1, the signal is desirable to signal transducer direction Useful signal, and the signal transmitted round about is garbage signal, the signal after waveguide wire bottom is reached will reversely to Transmission back, eventually passes through signal transducer and is changed into electric impulse signal 2, often interferometry device is final for electric impulse signal 2 Cause measurement output inaccurate.

The content of the invention

In view of this, the utility model is directed to a kind of signal transducer for having and shaking blanking function, to solve production The interference of raw garbage signal.

To reach above-mentioned purpose, what the technical solution of the utility model was realized in：

Signal transducer with vibrations blanking function, including current impulse generation device, signal transducer, magnet, ripple Wire, the electric current line of return and spring blanker, the ripple that the output signal that the current impulse generation device is produced passes through connection Wire transmission, the waveguide wire connects through connecting spring blanker behind the center of signal transducer, the spring blanker The electric current line of return is connect, the magnet is to be placed in the magnet that liquid level is represented inside float, follow the height of liquid level to move and move.

Further, the spring blanker is spring.

Relative to prior art, the utility model has the advantage that：

(1) by increasing spring blanker, useless micro- twisting signal absorption of generation is finally eliminated, signal is passed The each measurement period of sensor only detects an electric impulse signal, simplifies the post-processing difficulty of signal, it is ensured that measurement result Output it is stable.

(2) apparatus structure is simple, easily realizes.

Embodiment

It should be noted that in the case where not conflicting, the feature in embodiment and embodiment in the utility model can To be mutually combined.

Describe the utility model in detail below with reference to the accompanying drawings and in conjunction with the embodiments.

It is a kind of that there is the signal transducer for shaking blanking function, as shown in figure 1, including current impulse generation device 1, signal Sensor 2, magnet 3, waveguide wire 4, the electric current line of return 5 and spring blanker 6, what the current impulse generation device 1 was produced Output signal is transmitted by the waveguide wire 4 of connection, the waveguide wire 4 through signal transducer 2 center after connecting spring blanking Device 6, the connection electric current of spring blanker 6 line of return 5, the magnet 3 is to be placed in the magnetic that liquid level is represented inside float Iron, follows the height of liquid level to move and move.

The signal transducer 2 is air core coil, and the electric current line of return 5 is commonly conventional wire, the spring blanking Device 6 is elastomer, and the present embodiment selects the spring of metal material.

The current impulse produced by current impulse generation device 1 is transmitted by waveguide wire 4 and the electric current line of return 5, due to magnetic The fixed magnetic field and current impulse magnetic field interaction that iron 3 is produced make the small twisting letter that waveguide wire 4 is produced by Wertheim effect Number transmitted to both direction, transmit and pass through signal transducer 2 being converted to electric impulse signal 1 to the direction of signal transducer 2, the letter Number it is the useful signal needed.

And the signal transmitted round about is garbage signal, the garbage signal is passed to behind the expense of spring blanker 6 position, Micro- twisting signal absorbs final elimination by the spring of spring blanker 6, each measurement period of signal transducer 2 is only detected To an electric impulse signal, the post-processing difficulty of signal is simplified, finally stabilizes the output of measurement result.

Preferred embodiment of the present utility model is the foregoing is only, it is all at this not to limit the utility model Within the spirit and principle of utility model, any modification, equivalent substitution and improvements made etc. should be included in the utility model Protection domain within.
