Embodiment

The utility model proposes a kind of bandwidth detection device, it makes simple, and production cost is low, can use in various rugged environments, realizes having very high practical value easily.

The embodiment of the bandwidth detection device that the utility model is related as shown in Figure 1.Two parts mainly are set on the support 5 to be formed, leave air cleft between these two parts and detect space 9, a part is that first air cleft forms the unit, comprise by first inlet plate 6 and first air cleft and generate first air chamber 11 that plate 4 constitutes, and first inlet plate 6 and first air cleft generate between the plate 4 for being tightly connected, as Fig. 3, Fig. 4 and shown in Figure 5.One side of first inlet plate 6 is provided with inlet suction port 7 is installed on first air intake opening, 10, the first air intake openings 10.On first air cleft generation plate 4 first slit, 12, the first inlet suction ports 7 being set links to each other with the source of the gas 8 that has regulator.

Another part of sensor is the air cleft detecting unit, the air cleft detecting unit comprises the check-out console 3 of fixedlying connected with first air cleft generation plate 4, test chamber 13 is set on the check-out console 3, some gas detecting tubes 2 are set in the test chamber 13, and the position of gas detecting tube 2 is corresponding with the position that first air cleft generates first slit 12 on the plate 4.Gas detecting tube 2 links to each other with the signals collecting conversion and the computer information processing system 1 that have the pneumoelectric sensor.The quantity of the gas detecting tube 2 that is provided with in the test chamber 13 is many more, and the precision of detection is just high more.

Second air cleft that is connected with the source of the gas 8 that has regulator also is set on the support 5 forms the unit, as Fig. 6, Fig. 7 and shown in Figure 8.This second air cleft forms cellular construction and first air cleft, and to form cellular construction the same substantially, promptly inside be provided with second air chamber 11 ', second inlet suction port 7 of outer setting and second air chamber 11 ' be connected ' with second slit 12 of generation second air cleft '.Need to prove that this second air cleft forms second slit 12 in unit ' parallel with first slit 12 of first air cleft formation unit, second air cleft of second slit 12 ' generation passes that air cleft detects space 9 and its direction is perpendicular with the direction of first air cleft of described first slit, 12 generations, and in use, the band steel does not pass through from the air cleft detection space 9 that first air cleft forms between unit and the air cleft detecting unit, but in the space between first air cleft formation unit and second air cleft formation unit, pass through, accept detection.

First air cleft forms the working position of unit, second air cleft formation unit and air cleft detecting unit and puts as shown in Figure 1.First air cleft formation unit and air cleft detecting unit promptly form the laminar flow gas of horizontal direction in last horizontal positioned.Second air cleft formation unit is vertically being placed down, and promptly the laminar flow gas direction of Xing Chenging blows to the air cleft detection space 9 that first air cleft generates plate 4 straight up, and two-layer gas body is orthogonal.

During work, open source of the gas 8, gas will form first air chamber 11 of unit and second air chamber 11 ' interior generation voltage stabilizing gas that second air cleft forms the unit at first air cleft, and by first slit 12 and second slit 12 ' generation first air cleft and second air cleft, first air cleft and second air cleft detect space 9 at air cleft and interfere, result of interference makes two air clefts flow to atmosphere from different directions, and two air cleft width are 0.03mm～0.05mm.Regulate the gaseous tension of first air cleft and second air cleft and can control the flow direction that two air clefts are interfered back gas, regulate regulator in the present embodiment and make the air cleft of winning form the gaseous tension of unit greater than the gaseous tension in second air cleft formation unit.The band steel is passed through from the space that first air cleft forms between unit and second air cleft formation unit, as shown in Figure 2.When not being with steel to pass through, by regulating the gaseous tension of first air cleft and second air cleft, make and do not receive gas signal in the gas detecting tube 2, when the band steel passes through, because forming unit generation laminar flow gas, second air cleft is with steel to block, at this moment, the gas signal that only has first air cleft to form the unit generation can be received by gas detecting tube 2, and in computer system, show, just can't do not received by gas detecting tube 2 by the gas signal of first air cleft of being with steel to block, also just in computer system, can't show, can realize the measurement of bandwidth thus.

Obviously; the foregoing description only is for giving an example of being done clearly is described; and be not to qualification of the present utility model; for the person of ordinary skill of the art; can also make other multi-form variations on the basis of the above description; the form of the composition of air chamber for example; air cleft detecting unit and first air cleft formation unit can not be fixed together the gas signal that only need make gas detecting tube can receive air cleft and get final product; or the like; here also need not carry out exhaustive for all embodiments; and the conspicuous variation that is proposed thus still is within the protection domain of the present utility model.
