Description
Technical field
The utility model relates to a kind of title that adopts magnetic non-contact to measure weight of object, in particular, relates to a kind ofly have that precision is high, the life-span long, measures the electromagnetic levitation type platform scale of the distinguishing feature such as fast.
Background technology
The spring balance of the with good grounds Hooke's law design of weight metering method at present, according to the gentle title in sky of equilibrium principle design, according to the electronic scale of piezoelectric principle design.Spring balance the inside spring is subject to External Force Acting and distortion generation error and inefficacy gradually, the not high easy ageing failure of precision; Balance is subject to shape, volume and equilibrium point that stable reason is set with weighing object, measures more time-consuming; The electronic scale of piezoelectric principle design is simple and practical and have digital demonstration, easy to use, but electronic scale bracket fault is many, and serviceable life is short.
Utility model content
The utility model is in order to overcome weak point of the prior art, provides a kind of and can have that precision is high, the life-span is long, measure the electromagnetic levitation type platform scale of the distinguishing feature such as fast.
The utility model is achieved through the following technical solutions:
The utility model electromagnetic levitation type platform scale, is according to electromagnetism mechanics principle, by electromagnetic attracting force or support object, reaches mobile equilibrium and measures weight of object.Electromagnetic force F=nILB (F: magnetic force, n: coil turn, I: electric current, L: loop length, B: magnetic induction), the electric current by measuring coil can reflect magnetic force size, thereby measures weight of object.
The utility model electromagnetic levitation type platform scale, comprises metal support, magnetic force generator, magnetic weighing unit, recording controller, display.
Described metal support comprises: metal support pallet, cradling piece, consist of, by metal tube and sheet metal, made
Described magnetic force generator is comprised of electromagnet and coil, after energising, can produce huge magnetic field and magnetic force;
Described magnetic weighing unit is by sheet metal, to be made and had the metal tray of reverse magnetic pole, and is placed on the top of metal support pallet;
Described recording controller can be according to the variation of magnetic force generator current status used, is used for the quality that analytical calculation magnetic weighing unit weighs, and recording controller is placed on to cradling piece the inside;
Described display is for showing that recording controller calculates the qualitative data of weighing, and is placed on display the upper end of cradling piece;
Described magnetic force generator and recording controller, display interconnect with wire;
The present invention adopts magnetic non-contact to measure weight of object, has that precision is high, the life-span long, measure the distinguishing features such as fast.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model electromagnetic levitation type platform scale;
Fig. 2 is the circuit theory diagrams of the utility model electromagnetic levitation type platform scale.
Embodiment
Below in conjunction with the drawings and specific embodiments to the explanation of the utility model detail.
The schematic diagram of the utility model electromagnetic levitation type platform scale as depicted in figs. 1 and 2, is characterized in that: comprise by metal support (1), magnetic force generator (2), magnetic weighing unit (3), recording controller (4), display (5) and forming.
Described metal support (1) comprising: metal support pallet (6), cradling piece (7) form, and by metal tube and sheet metal, are made;
Described magnetic force generator (2) is comprised of electromagnet (8) and coil (9), after energising, can produce huge magnetic field and magnetic force;
Described magnetic weighing unit (3) is by sheet metal, to be made and had the metal tray of reverse magnetic pole, and is placed on the top of metal support pallet (6);
Described recording controller (4) can be according to the variation of magnetic force generator current status used, is used for the quality that analytical calculation magnetic weighing unit (3) weighs, and recording controller (4) is placed on to cradling piece (7) the inside;
Described display (5) is for showing that recording controller calculates the qualitative data of weighing, display (5) being placed on to the upper end of cradling piece (7);
Described magnetic force generator (2) and recording controller (4), display (5) interconnect with wire.
Embodiment: the required article of weighing are placed on to magnetic weighing unit (3) above, when not switching on, magnetic weighing unit (3) drops on above metal support pallet (6), after magnetic force generator (2) energising, electromagnet (8) and coil (9) produce huge magnetic field and magnetic force, because magnetic weighing unit (3) itself can rise at the effect magnetic weighing unit (3) of magnetic field and magnetic force and the article of load-carrying with the reverse magnetic pole of meeting, when carrying the article of weighing, magnetic weighing unit (3) rises while leaving metal support pallet (6), at this moment recording controller (4) starts to calculate at this moment magnetic force generator (2) voltage used, the series of parameters such as electric current are calculated alleged heavy quality by analysis meter, and by being connected to display (5) on recording controller (4), demonstrate the concrete data of the quality of weighing.
The present invention adopts magnetic non-contact to measure weight of object, has that precision is high, the life-span long, measure the distinguishing features such as fast.
