Description
Technical field
The utility model relates to densitometer technical fields, and in particular to a kind of U-shaped concussion method digital densimeter.
Background technique
In the analysis test of organic compound, one of physical constant as measured matter, density is mainly used in meter
Amount, cost accounting.Density is the mass number of contained substance in unit volume, i.e. quality (m) and volume (V) at the specified temperature
The ratio between.The measurement method of the density of liquid product mainly has: densimeter method, Westphal balance method, density bottle method.To highly volatile
Oil product and organic solvent can only use density bottle method.
In most cases, densimeter method is generally all selected in the measurement of the density of liquid substance, but is surveyed with densimeter method
The temperature of sample can change in graduated cylinder when amount, and manually estimate densitometer when be easy to appear biggish deviation, cause to survey
It is larger to measure resultant error.
And density bottle method is the unique method of accurate measurement of species density, it needs to be used in conjunction with balance, measures a certain known
Definite volume sample quality, the density of sample only need to can obtain its quality divided by volume.If but surveying in air
Amount, the mass loss as caused by surrounding air are often ignored, and generate certain error in measurement.Want precise measurement
It just has to carry out under vacuum conditions, this cannot achieve in actual operation.

Specific embodiment
Below in conjunction with attached drawing, by specific embodiment, the utility model will be further described, these embodiments are only used for
Illustrate the utility model, is not the limitation to scope of protection of the utility model.
As shown in Figure 1-Figure 3, the utility model provides a kind of U-shaped concussion method digital densimeter comprising outer layer heat preservation
In the outer layer thermal insulator 1, material is the U-shaped sample cell 2 of glass for body 1 and setting；The outer layer thermal insulator 1 and described U-shaped
It is provided with thermometer hole 3 on the cavity formed between sample cell 2, temperature sensor can be set in the thermometer hole 3, such as hot
Galvanic couple etc.；Magnet steel 4 is fixed on the U-shaped sample cell 2, the shape of magnet steel 4 can be rectangular；The magnet steel 4 can be by viscous
Knot is fixed on the bottom of the U-shaped sample cell 2.The outer layer thermal insulator 1 is enclosed construction；The thermometer hole 3 and the U-shaped sample
The top of the outer layer thermal insulator 1 is arranged in the nozzle preformed hole of quality control 2.
The principles of the present invention are: using the oscillation frequency of the U-shaped sample cell 2 of glass caused based on electromagnetism, that is, utilizing
One block of magnet steel 4 is fixed on U-shaped sample cell 2, so that it is generated vibration by oscillator, the vibration period of U-shaped sample cell 2 will be vibrated
Sensor measurement obtains.Each U-shaped sample cell 2 has its characteristic frequency or by natural frequency vibration.When in U-shaped sample cell 2
It can change full of its frequency after object, different substance frequency variations will be different, and frequency is pipe inner stuffing matter
The function of quality.When the quality of substance increases, its frequency can be reduced, i.e. vibration period T increases.Cucumber is selected when measurement
As standard substance, measured matter is calculated by the difference of oscillation frequency between measured matter and standard substance after measurement frequency
Density value.
When the utility model carries out density measure, first outer layer thermal insulator 1 is heated, then inject a sample into U-shaped sample cell 2,
