Abstract
The invention discloses a high precision electronic balance which comprises a push-pull cover, a weighing tray, a base plate, a movable plate and a calibration device. The base plate is provided with four first through holes, a motor is fixed at the right end of the base plate, the movable plate is provided with four second through holes, a gear is fixed at the right end of the movable plate, and the motor drives the movable plate to move through the gear. The high precision electronic balance enables air temperature around the weighing tray to be close to air temperature around the calibration device through air convection, eliminates difference of buoyancy of objects in the weighing tray and calibration device buoyancy, and is small in measuring result error and accurate in measuring result.
Description
Technical field
The present invention relates to object weighing field, particularly relate to a kind of high-precision electronic balance.
Background technology
Electronic balance is the object weighing equipment that a kind of degree of accuracy is high, sensitivity is good, and the variation of external environment condition is very big to the measurement result influence of electronic balance.The thermal capacity of electronic balance weighing chamber is generally less than the thermal capacity of electronic balance sub-body part; When the operation of environment temperature generation marked change or electronic balance during distribute heat; Weighing room and electronic balance sub-body part will produce temperature difference, and atmospheric density can be different under the different temperatures, thereby the buoyancy of object is different with the buoyancy of calibrating installation in the electronic balance in the weighing plate; Make the measurement result occurrence of errors, the object mass measurement is inaccurate.
Summary of the invention
The technical matters that the present invention mainly solves provides the little high-precision electronic balance of a kind of measuring result error.
For solving the problems of the technologies described above; The technical scheme that the present invention adopts is: a kind of high-precision electronic balance is provided, comprises push-and-pull cover, weighing plate, base plate, movable plate and calibrating installation, four first through holes are arranged on the said base plate; Said base plate right-hand member is fixed with motor; Four second through holes are arranged on the said movable plate, and said movable plate right-hand member is fixed with gear, shown in motor move through the said movable plate of said gear drive.
In preferred embodiment of the present invention, first thermal detector is arranged around the said weighing plate, second thermal detector is arranged around the said calibrating installation.
In preferred embodiment of the present invention, when covering on temperature difference that temperature that said first thermal detector records and second thermal detector record less than preset value, said push-and-pull can open.
In preferred embodiment of the present invention, the temperature difference that the temperature that said first thermal detector records and second thermal detector record is during greater than preset value, and said motor makes said first through hole and said second through hole corresponding through the said movable plate of said gear drive.
In preferred embodiment of the present invention, said first through hole and said second through hole are four.
The invention has the beneficial effects as follows: high-precision electronic balance of the present invention; Make weighing plate and calibrating installation ambient air temperature approaching through cross-ventilation; It is approaching that atmospheric density also reaches; The difference of object buoyancy and calibrating installation buoyancy in the elimination weighing plate, measuring result error is little, makes measurement result accurate.
Description of drawings
Fig. 1 is the structural representation of high-precision electronic balance one preferred embodiment of the present invention;
The mark of each parts is following in the accompanying drawing: 1, push-and-pull cover, 2, weighing plate, 3, base plate, 4, movable plate; 5, calibrating installation, 6, first thermal detector, 7, second thermal detector, 8, first through hole; 9, second through hole, 10, motor, 11, gear, 12, manipulater; 13, display, 14, processor, 15, detectors of load.
Embodiment
Below in conjunction with accompanying drawing preferred embodiment of the present invention is set forth in detail, thereby protection scope of the present invention is made more explicit defining so that advantage of the present invention and characteristic can be easier to it will be appreciated by those skilled in the art that.
See also Fig. 1, the present invention provides a kind of high-precision electronic balance, comprises push-and-pull cover 1, weighing plate 2, base plate 3, movable plate 4 and calibrating installation 5; Four first through holes 8 are arranged on the said base plate 3; Said base plate 3 right-hand members are fixed with motor 10, and four second through holes 9 are arranged on the said movable plate 4, and said movable plate 4 right-hand members are fixed with gear 11;, shown in motor 10 drive said movable plate 4 through said gear 11 and move.
Around the said weighing plate 2 among the present invention first thermal detector 6 is arranged, around the said calibrating installation 5 second thermal detector 7 is arranged.
The temperature difference that the temperature that said push-and-pull cover 1 among the present invention records at said first thermal detector 6 and second thermal detector 7 record can be opened during less than preset value.
The temperature difference that the temperature that said first thermal detector 6 among the present invention records and second thermal detector 7 record is during greater than preset value, and said motor 10 drives said movable plate 4 through said gear 11 and makes said first through hole 8 and said second through hole, 9 correspondences.
The principle of work of high-precision electronic balance according to the invention is: the temperature difference that the temperature that said first thermal detector 6 records and second thermal detector 7 record is during greater than preset value, and said push-and-pull cover 1 can not be opened, and shows on the display 13 " temperature difference is excessive "; Manipulater 12 is provided with; Be transferred to motor 10 driving movable plate 4 signals through processor 14, motor 10 drives movable plate 4 through gear 11, makes said first through hole 8 and said second through hole 9 corresponding one by one; Air carries out convection current; The temperature difference that the temperature that records when said first thermal detector 6 and second thermal detector 7 record shows " temperature difference is fit to " during less than preset value on the display 13, manipulater 12 is given motor 10 through processor 14 transmission shutdown signals; Motor 10 drives movable plate 4 through gear 11 and moves round about; Said first through hole 8 is staggered with said second through hole 9, stop cross-ventilation, can measure.Open push-and-pull cover 1, object is put on the weighing plate 2, and 5 pairs of detectors of load 15 of calibrating installation apply power, and detectors of load 15 is sent signal and handled for processor 14, obtains data and issues display 13, shows the object quality on the display 13.
The high-precision electronic balance that the present invention discloses, said first through hole and said second through hole are four, through hole very little the convection current time long; Through hole influences weighing precision too much makes the air generation convection current in weighing room and the electronic balance sub-body through the through hole on base plate and the movable plate; Make weighing plate and calibrating installation ambient air temperature approaching, it is approaching that atmospheric density also reaches, the difference of object buoyancy and calibrating installation buoyancy in the elimination weighing plate; Measuring result error is little, makes measurement result accurate.
