Embodiment
Fig. 3 is the inner backsight structural representation of the utility model, and Fig. 4 is that the A of Fig. 3 is to partial schematic diagram.Shown in Fig. 3,4, the utility model is a kind of resistance-type automobile fuel gas tensimeter, comprise index dial 1, indicator 2, helical Bourdon tube 3, sector gear 5, central gear axis 4, main body joint 7, wherein, fixed installation is useful on the chromacoder that amount of pressure is converted to resistance signal output on core of pressure meter base plate 6.This chromacoder can comprise a printed circuit board 8, that is used for the output resistance signal be used for along with amount of pressure change and the brush dish 9 of change in location and when brush dish 9 is positioned at diverse location all with the contacted brush in two ends of the different resistance values of printed circuit board 8.
Brush dish 9 is in the installation of central gear axis 4 rear ends and along with central gear axis 4 rotates together; On by brush dish 9 central shaft straight lines, the central shaft both sides respectively are provided with an end along with brush dish 9 brushes that rotate, that have conducting function.
Fig. 5 is the synoptic diagram of printed circuit board 8, and Fig. 6 is the utility model circuit theory diagrams.Printed circuit board 8 is provided with the common port contact area A with conducting function, resistance terminal contact area D1, D2, D3, D4 and the D5 that 5 have conducting function, and the resistance terminal contact area is adjacent in twos, is in series with resistance R between the described adjacent two resistance terminal contact areas.The sliding end of one side brush contacts with common port contact area A conduction, is common port brush 10; The sliding end of opposite side brush contacts with described resistance terminal contact area conduction, is resistance terminal brush 11, and resistance terminal is equipped with four resistance R that are in series 1, R2, R3, R4 and R5.Common port brush 10 is connected to output terminal Out1 and Out2 respectively with resistance terminal brush 11, exports different resistance value signals.
Shown in Fig. 1,2,3 and 4, when vehicle-mounted gas-holder pressure was zero, tensimeter indicator 2 was in the zero-bit of index dial 1, and the sliding end of the resistance terminal brush 11 on the brush dish 9 is in the D1 district on the printed circuit board, and the output resistance signal is zero.When the pressure of vehicle-mounted gas-holder raises gradually, manometric helical Bourdon tube 3 driven gear central shafts 4 rotate, central gear axis 4 front ends drive indicator 2 and rotate, indicated pressure raises, the brush that the rear end drives on the brush dish 9 rotates, the contact region of brush contact on printed circuit board 8 rotates, and changes resistance.And the notch cuttype by resistance raises, and reflects that the pressure of vehicle-mounted gas-holder raises.When the pressure of vehicle-mounted gas-holder descended, its work engineering was just in time opposite during with rising.
