Above-mentioned weight sensing instrument, wherein, described display is a light-emitting diode display.
Above-mentioned weight sensing instrument, wherein, described LOAD CELLS is the resistance-strain load sensor.
A kind of weight sensing instrument of the utility model, through with LOAD CELLS, A converter, single-chip microcomputer and keyboard and display be integrated into a control box, make whole weight sensing instrument be convenient to operation more and move, good looking appearance is generous, and is simple in structure, convenient and practical.
Description of drawings
Fig. 1 is the structural representation of a kind of weight sensing instrument of the utility model;
Fig. 2 is the annexation figure in kind of a kind of measuring instrument of the utility model.
Embodiment
Below in conjunction with Figure of description a kind of weight sensing instrument of the utility model is done further detailed explanation.
See also shown in Figure 1ly, a kind of weight sensing instrument comprises LOAD CELLS 1, A/D converter 2, single-chip microcomputer 3 and keyboard 4 and display 5; Wherein, A/D converter 2 is connected with LOAD CELLS 1 and single-chip microcomputer 3 respectively, and single-chip microcomputer 3 also is connected with keyboard 4 and display 5.Wherein, A/D converter 2, single-chip microcomputer 3 and keyboard 4 and the display 5 integrated control boxs 00 that become make this weight sensing instrument be divided into control box 00 and LOAD CELLS 1 two parts on the whole, and the LOAD CELLS in the present embodiment 1 are the resistance-strain type load sensor; It is wide in range that it has measurement range; Reliable and stable, accuracy is high, advantages such as technical maturity; A/D converter 2 adopts CS5523A/D converter or CS5524A/D converter; The WV of this A/D converter of two types is merely 5V; And saved pre-amplification circuit, circuit for signal conditioning, analog switch etc., made that the structure of whole A/D converter is simple more, stability is high, reliable; Display 5 adopts light-emitting diode display, makes weight measurement convenient, directly perceived.
The principle of work of the weight sensing instrument of the utility model is following: at first; LOAD CELLS 1 is converted into the voltage signal with its direct ratio with the quality signal that collects; And with voltage signal send to D converter 2 with the voltage analog signal conversion digital signal; And after sending single-chip microcomputer 3 to and handling, display 5 will represent accordingly that the digital signal of weight shows, accomplish the measurement of alleged quality and read.
A kind of weight sensing instrument of the utility model, through with LOAD CELLS, A converter, single-chip microcomputer and keyboard and display be integrated into a control box, make whole weight sensing instrument be convenient to operation more and move; Weight measurement is convenient, and is directly perceived, efficient; Good looking appearance is generous, and is simple in structure, convenient and practical.
Should be pointed out that foregoing is the enumerating of preferred forms of a kind of weight sensing instrument of the utility model, the part of wherein describing in detail to the greatest extent is construed as with the general fashion in present technique field and implements.Simultaneously, for one of ordinary skill in the art, equivalent transformation and the modification in not departing from the utility model spirit category, the utility model done all will fall within the claim protection domain of the utility model.
