Abstract
The utility model discloses a digital displaying type densimeter which belongs to the field of measuring density of mechanical measurement. Floats hung on a force sensor are all immersed in liquid to be measured in a liquid containing container. Buoyancy born by the floats is converted to an electric signal through the force sensor and then sent to a secondary meter to be processed. Because the density of fluid to be measured is in direct proportion with the buoyancy born by the floats, the secondary instrument can directly display the density value of measured liquid. If matched and connected with the densimeter, a printer can print a test result.
Description
The utility model belongs to the density measurement technology of mechanics metering, it has numeral and shows fluid to be measured density value function, it is to be dipped in the test solution with float by measuring, suffered buoyancy is measured by high precision sensor, and be converted to electric signal and send into treated its density value of direct demonstration of secondary instrument, and can go out measurement result by printer prints.
The densitometer that generally uses in laboratory and the work all is the glass overstatement basically at present, as pioscope, petroleum densitmeter, and electrolytic solution meter, alcohol meter or the like.It is divided into body, main and ballast cell three parts.Body is the hollow round column body of a round section, and there is a center of gravity its lower end, and be used to pack into lead shot or mercury etc. are as ballast, and its purpose makes overstatement obtain necessary weight, and its center of gravity is descended.Vertically float in the liquid.Ballast will clog or use the sealing wax sealing with cotton, and ballast is not moved, and makes overstatement tilt to cause reading error in order to avoid influence the variation of overstatement centre of gravity place.The main upper end of overstatement requires welding.Main is a thinner glass tube, and the pipe and the central shaft of body are coincided.Be placed with the calibration paper that carries out scale according to density or percent concentration the main planted agent.Calibration paper top touch with glue and main inwall, in case slide or come off.The glass overstatement has following deficiency as seen from the above: 1. technological reason makes its main be difficult to absolute the coincidence with the central shaft of body.2. so the thin ballast of the very thin wall of the main main that can not kick the beam again very easily damages.3. calibration paper is affixed on the main inwall and is difficult to cement and easily comes off or slide.4. read the meniscus indicating value and also easily cause big reading error.5. a class densitometer such as petroleum densitmeter one cover are formed by tens, specifically use many very inconvenience of use when especially density range is big slightly.6. need carry out the capillary correction in the calibrating, so the operational computations complexity.7. the lower and easy breakage of accuracy and qualification rate.
The purpose of this utility model is: design a kind of simple in structure, easy to use, accuracy is high, failure rate is low, measurement range is applicable to the practical advanced digital display type densitometer of whole liquid, to satisfy the need of all kinds of fluid density tests.
Technical scheme that the utility model adopts is: it is by 1. precise force-measuring sensors, 2. support, 3. liquid holding dish, 4. measurement dedicated float, 5. intelligent secondary instrument, 6. print system is formed: support (2) is connected with pedestal, sensor (1) is fixed on the support 2, sensor (1) is connected with float (4) by hang spring, liquid holding dish (3) is located on the pedestal, float immerses in the liquid holding dish, and force cell becomes change in voltage to be input in the intelligent secondary instrument (5) by aviation plug and signal wire the change transitions of buoyancy like this, is giving printer by lead.
Here: 1. precise force-measuring sensor, select resistance-strain type of dynamometer sensor for use, it is a device that suffered power value is changed into electric signal.It is to be that resistance strain gage is affixed on the elastic body of high stability and is connected into an electric bridge when connecting bridge to it when pressing by four force sensitive elements, and then the variation of institute's stress value will cause the electric bridge out of trim, thus the voltage signal that output is directly proportional with the power value.
2. support, the fixed mount that is provided with for fixation of sensor exactly.
3. liquid holding dish is exactly the container of splendid attire fluid to be measured, and the test solution of its splendid attire should guarantee the whole measurement dedicated float of submergence.
4. measurement dedicated float, be one be placed in the measured liquid device it be processed to streamlined, material can be respectively needs and selects glass, brass or other hot temperature coefficient materials with smaller for use by measured medium and user, its volume is relatively stable, weight should be able to guarantee not answer the emersion liquid level when being subjected to test solution buoyancy, its weight can not exceed the maximum permissible value of force cell simultaneously.
5. intelligent secondary instrument is the advanced intelligent weighing instrument that adopts microcomputer technology, it not only can carry out the ultra-weak electronic signal of force transducer processing and amplifying and display density value, simultaneously, its stronger parameter, set-up function can satisfy the whole requirements of user to the fluid to be measured density measurement.As: measurement range is much; Scale division value how much; Zero point, tracing step was much, declared steady scope, and scaling position or the like is followed one's inclinations set.It has printing and binary-coded decimal output interface simultaneously, can connect the printer prints measurement result, also can be used for management or other function expansion with computer networking.
6. printer, its effect are to guarantee that measurement data is true and reliable.
Accompanying drawing is the overall schematic of the utility model digital display type densitometer device.
At first force cell 1 is fixedly mounted on the support 2 by securing member, will lies in the hang spring of measuring on the dedicated float 4 then and be suspended on the coupling ring of force-detecting position of sensor 1.Like this when measuring dedicated float 4 and all be dipped in the measured liquid in the liquid holding dish 3, measure the suffered buoyancy that is directly proportional with test solution density of float 4 and will pass to force cell 1 and force cell 1 will be along with the variation of suffered buoyancy by hang spring, voltage signal of linear output, this small voltage signal is input in the intelligent secondary instrument 5 by aviation plug and signal wire, secondary instrument 5 with have the function of amplifying and handling this electric signal, and demonstrate measured fluid density value.Connect printer 6 and can print measurement result.Here sensor 1, support 2, secondary instrument 5, printer 6 all are loaded in the same instrument box, but opening an aperture on instrument box stays the force-detecting position coupling ring of force cell outside the case, measure float to hang hang spring and then to connect, be implemented in the liquid holding dish measurement fluid to be measured.
