Abstract
Disclosed is an electronic spring balance, which includes a fixed support and a moving support, and between the fixed support and moving support is connected with a spring, and the utility model also includes an electronic circuit which is composed of a capacitive transducer, and a liquid crystal display screen, the capacitive transducer has a control IC, a main grid, a secondary grid which are connected with the moving support or fixed support respectively, the control IC transmits signals to a emission grid of the capacitive transducer, and receives displacement signals from a receiver pole of the capacitive transducer to control the LCD to display the corresponding weight number. The electronic spring balance uses the capacitive transducer to measure the deformation displacement of the spring balance, and can be made into high precision spring balance.
Description
Technical field
The utility model relates to a kind of electronics spring balance.
Background technology
Generally all at 500 below the calibration, precision can not be done very highly for the spring balance of market circulation now, its scale.And the capacitive transducer of the major types that capacitor grid transducer is a development in recent years to get up is widely used in the measurement of digimatic calipers, milscale, altimeter, coelosphere and machine tool travel.Capacitor grid transducer generally comprises the inferior grid that induction electrode that the main grid be made up of emitter and receiving pole and polylith be separated by by ground is formed.Main grid can move on the emission grid, responds to corresponding displacement signal by receiving pole, exports control IC to, thereby can measure displacement.
Summary of the invention
The purpose of this utility model is to provide a kind of high-precision electronics spring balance.
In order to achieve the above object, electronics spring balance described in the utility model comprises fixed rack and moving support, be connected spring between moving support and the fixed rack, it is characterized in that: the electronic circuit that also has a capacitor grid transducer that is connected with above-mentioned moving support or fixed rack respectively by control IC, main grid, inferior grid and LCDs to form, control IC transmits to the emission grid of capacitor grid transducer, and the displacement signal of the receiving pole of reception capacitor grid transducer, LCD shows corresponding weight numeral with the control LCD.
Electronics spring balance described in the utility model adopts the deformation displacement of capacitor grid transducer measuring spring scale, can make the high precision spring balance.Adopt capacitor grid transducer to measure gravitational displacement, can be in the 10mm gravitational displacement, obtain calibration and be 1000 digital display precision.For example, the spring balance of 10kg, 10mm displacement, minimum division value is: 10*1000/1000=10g, and cost is low, easily produces.
Description of drawings
The circuit diagram of Fig. 1 electronics spring balance described in the utility model;
Fig. 2 shows structural representation for the A-A of Fig. 1 cuts open;
Fig. 3 is the structural representation of electronics spring balance described in the utility model.
Embodiment
The capacitor grid transducer part: as shown in Figure 1, E is for launching grid, being made up of polylith emitter piece, and every emitter piece is made up of eight emitters of isolating mutually again, and same plane also has receiving pole S, whole assembly is called main grid R here.Inferior grid M is made up of by the induction pole that ground is separated by polylith.As shown in Figure 1, main grid and time grid are flat mutually folded, and inferior grid are stacked on the emission grid plane of main grid, can left and right relatively motion.The induction pole of inferior grid M is just respectively covered four emitters with the isolation utmost point, sees Fig. 2.Eight emitters in every emitter corresponding with 00,01 of IC ... 08 mouthful of connection.During work, IC O0-O7 transmits to emission grid E, and its adjacent bipod phase differential is 45 degree.When inferior grid M was mobile on the emission grid, receiving pole S sensed corresponding displacement signal.Handle the back through IC and show displacement in LCDs.
The weight conversion: as shown in Figure 3, fixed rack 1 is connected with an end of main grid R and spring 2; Moving support 3 is connected with the other end of time grid M and spring 2.Be out of shape Δ M when weight makes spring 2, emission grid E produces displacement M with time grid, and receiving pole S receives corresponding displacement signal, shows displacement in LCDs after the IC processing.Show weight with this displacement relation.For example, the spring balance of 10Kg, 10mm displacement shows 10.00Kg.Certainly, above-mentioned fixed rack is connected with time grid, and it also is a kind of embodiment of the present utility model that moving support is connected with main grid.
Claims (1)
1, a kind of electronics spring balance, comprise fixed rack (1) and moving support (3), be connected spring (2) between moving support (3) and the fixed rack (1), it is characterized in that: the electronic circuit that also has a capacitor grid transducer that is connected with above-mentioned moving support (3) or fixed rack (1) respectively by control IC, main grid R, inferior grid E and LCDs to form, control IC transmits to the emission grid E of capacitor grid transducer, and the displacement signal of the receiving pole S of reception capacitor grid transducer, LCD shows corresponding weight numeral with the control LCD.
