Abstract
The invention discloses a differential transformer capable of measuring a liquid concentration change. The differential transformer comprises a magnetic-conducting wireframe, wherein a primary coil is wound on the left rim of the magnetic-conducting wireframe; two segments of hollow cavities which are arranged up and down are arranged in the right rim of the magnetic-conducting wireframe; the lateral wall of the right rim of the magnetic-conducting wireframe corresponding to the upper end and the lower end of each segment of hollow cavity is connected with interfaces which are communicated with the corresponding hollow cavity; a secondary coil is wound on the position, corresponding to each hollow cavity, on the right rim of the magnetic-conducting wireframe; and two groups of secondary coils are reversely connected in series. By the differential transformer, measurement of the liquid concentration change can be achieved; and the differential transformer has relatively high measurement sensitivity and accuracy.
Description
Technical field
The present invention relates to field transformer, a kind of differential transformer measuring strength of fluid change.
Background technology
Transformator be the principle utilizing electromagnetic induction to change the device of alternating voltage, differential transformer is the one of transformator
Kind, it is used for measuring the non electrical quantity parameters such as displacement, pressure, vibration, but still not used for the differential transformation measuring strength of fluid change
Device structure.
Summary of the invention the technical problem to be solved is to provide a kind of differential transformer, and its structure is ingenious, can be real
Now the measurement to strength of fluid change, has higher measurement sensitivity and accuracy；Solve prior art differential transformer
The problem that cannot measure strength of fluid change.
In order to solve above-mentioned technical problem, the technical solution adopted in the present invention is:
A kind of differential transformer measuring strength of fluid change, includes magnetic conduction wire frame, and magnetic conduction wire frame left frame limit is wound around
There is primary coil, it is characterised in that: described magnetic conduction wire frame right frame limit has two sections of cavitys being arranged above and below, every section of cavity
Being connected to the interface connected with cavity on the magnetic conduction wire frame right frame avris wall that upper and lower end is corresponding, described magnetic conduction wire frame is right
In side frame edge, corresponding each empty cavity position is wound with secondary coil, two groups of secondary coil differential concatenations respectively.
Described a kind of differential transformer, it is characterised in that: corresponding each sky on described magnetic conduction wire frame right frame avris wall
Upper and lower end position, chamber further respectively has positioning convex point.
The working method of the present invention is；
In the present invention, in two sections of cavitys, each lead into same fluid to be measured, then close one of them cavity, another cavity
Connecting with fluid to be measured, if fluid to be measured concentration is constant, the most now the two total output voltages of secondary coil are zero, work as fluid to be measured
During concentration change, the secondary coil magnetic flux corresponding with the empty cavity position of fluid to be measured connection changes, then two secondary coil
Total output voltage changes, and total output voltage can be by being calculated with strength of fluid variation relation.
The invention have the advantage that
The present invention can realize the measurement to strength of fluid change, has higher measurement sensitivity and accuracy.
Accompanying drawing explanation
Fig. 1 is present configuration schematic diagram.
Detailed description of the invention
Shown in Figure 1, a kind of differential transformer measuring strength of fluid change, include magnetic conduction wire frame 1, magnetic conduction line
It is wound with primary coil 2 on frame 1 left frame limit, described magnetic conduction wire frame 1 right frame limit has two sections of cavitys being arranged above and below 3,
It is connected to the interface 4 connected with cavity 3 on the magnetic conduction wire frame 1 right frame avris wall that every section of cavity 3 upper and lower end is corresponding, leads
On magnet-wire frame 1 right frame limit, corresponding each empty cavity position is wound with secondary coil 5, two groups of secondary coil 5 differential concatenations respectively.Institute
State corresponding each cavity 3 upper and lower end position on magnetic conduction wire frame 1 right frame avris wall and further respectively have positioning convex point 6.
