Description
Technical field
The utility model belongs to liquid level gauge field, and in particular to a kind of capacitance type liquid level for truncating simultaneously self-adapting medium
Meter.
Background technology
Common capacitance level gauge, normal length are fixed, it is impossible to are adjusted.When in use, if length surpasses
It is long, it can cause to interfere with container bottom, lead to install failure.This just needs to know accurately container dimensional in advance, so as to customized
The liquid level gauge of length corresponding to the container.Since there are many type of container, the fitting depth needed also differs, can not be to liquid level
Meter carries out high-volume stock, and adverse effect is produced to the production cost kimonos phase of working.In order to adapt to market for greater flexibility
Demand is supplied immediately, need to improve out from structure a kind of length can truncated capacitance level gauge, so as to fulfill getting ready the goods in batches
With quick response order demand.The disclosed a kind of energy of utility model application No. is 201120564213.9 realizes what is calibrated automatically
Intelligent boiler liquid level of steam drum meter, the capacitance liquid level meter of simultaneously self-adapting medium can be truncated by having developed a kind of length on this basis.
Utility model content
The purpose of this utility model is to need to produce after specifying to solve the range size of common capacitance level gauge,
Be inconvenient to get ready the goods, and a kind of capacitance level gauge for truncating simultaneously self-adapting medium provided.
To achieve the above object, the utility model adopts the following technical solution：A kind of electricity for truncating simultaneously self-adapting medium
Appearance formula liquid level gauge, including electronics storehouse and electrode, electrode includes inner and outer electrodes, and interior electrode exterior is provided with insulation sleeve, institute
State at least two sections from top to bottom of interior electrode, electrode is fixed on a shaft insulation in the multistage, two neighboring interior electrode it
Between it is mutually isolated, electrode and insulation sleeve are placed in a rubber stopper in bottom one section, and rubber stopper is placed in lower end cap, under
Plug is used for blocking the gap between inner and outer electrodes.
Three segment electrodes are provided in the insulation sleeve, are denoted as interior electrode I, interior electrode II, interior electrode III respectively from top to bottom.
The multistage inner electrode diameter is equal, the proportional relationship of length.
The dispatch from foreign news agency extremely metal tube, lower end cap are conductor or non-conductor.
The rubber stopper and lower end cap are removable.
Relative to the prior art, the utility model provides a kind of capacitance level gauge for truncating simultaneously self-adapting medium, only
It needs to block the liquid level gauge in electrode section region in third section with tool, it is possible to reduce the length and amount of liquid level gauge
Journey, and can self-adapting medium, reach live flexibly installation and the requirement of production stock.
Description of the drawings
Fig. 1 is the structure diagram of the utility model.
Fig. 2 is the structure diagram that the utility model blocks state.
Specific embodiment
The utility model is described in further detail with reference to the accompanying drawings and detailed description.
As depicted in figs. 1 and 2, the utility model provides a kind of capacitance level gauge for truncating simultaneously self-adapting medium, packet
Electronics storehouse 1 and electrode are included, electrode includes inner and outer electrodes 2, and external electrode 2 uses metal tube, and interior electrode exterior is provided with absolutely
Edge set 3, interior electrode can set multistage, at least two sections from top to bottom, preferably, the utility model uses electrode in three sections,
It is denoted as interior electrode I 4, interior electrode II 5, interior electrode III 6 respectively from top to bottom, electrode is fixed on a shaft insulation in three sections, phase
Mutually isolated between adjacent two interior electrodes, three inner electrode diameters are equal, length into certain proportionate relationship, it is one section bottom in
Electrode and insulation sleeve 3 are placed in a rubber stopper 7, and rubber stopper 7 is placed in lower end cap 8, and rubber stopper 7 and lower end cap 8 can weigh
Multiple dismounting uses, and lower end cap 8 is used for blocking the gap between inner and outer electrodes 2, and lower end cap can be conductor or non-conductor.
The operation principle of the utility model is as follows：Interior electrode I 4, interior electrode II 5, interior electrode III 6 respectively with insulation sleeve 3, outer
Electrode 2 forms three sections of proportional capacitance structures, when medium lifts between insulation sleeve 3 and external electrode 2, can be imitated due to dielectric
The variation of capacitance should be caused, the level value of medium can be obtained by conversion.
When liquid level floods interior electrode III 6 completely is raised to interior electrode II 5, interior electrode I 4 is formed with insulation sleeve 3, external electrode 2
First segment capacitance structure in without medium, the zero reference as current media.Simultaneously electrode 6 and insulation sleeve 3 in third section,
The third section capacitance structure that external electrode 2 is formed floods in the medium completely, the reference of working to the last minute as current media.It works to the last minute by zero
Reference value can calculate the dielectric coefficient of current media, so as to be compensated to the measurement of whole liquid level.
Which forms the adaptive performance to measuring medium, i.e., the different liquid medium D-value of dielectric constant no matter surveyed
Not much, liquid level gauge can be adjusted and export accurate level value automatically.
When needing to truncate liquid level gauge, first lower end cap 8 and rubber stopper 7 are removed, truncate third section electricity with tool later
Hold structure to suitable range, refill rubber stopper 7 and lower end cap 8 up later.When three sections of capacitance structures all flood in the medium
When, by comparing three sections of capacitances, it can be determined that the third section capacitance structure gone out after truncating blocks ratio, is truncated so as to calculate
Zero afterwards works to the last minute reference value, re-establishes new compensation system, here it is the adaptive principles after truncation.
The above is the preferred embodiment of the utility model, it is noted that for those skilled in the art,
The present utility model is not limited to the above embodiments, under the premise of the utility model general idea is not departed from, can also make
Several changes and improvements, these should also be considered as the scope of protection of the utility model.
