Abstract
The utility model relates to an angle/voltage converter which makes use of the change value of voltage to test the converting angle. The utility model comprises a coaxial rotary double-connecting potentiometer, of which the left end of a slide potentiometer and the right end of the slide potentiometer are connected with the positive pole of the power. The right end of the slide potentiometer and the left end of the slide potentiometer are connected with the negative pole of the power. One end of the slide potentiometer is connected with another slide potentiometer, and the other ends of the two slide potentiometers are connected with the power; a voltmeter is connected with the slide points of the two slide potentiometers; and the coaxial rotary double-connecting potentiometer is fixed to a level steel plate whose longer side is parallel to the horizontal face, and whose shorter side is vertical to the horizontal face; and the rotary axis of the coaxial rotary double-connecting potentiometer is fixedly connected with a drop hammer. The converter converts the angle change to voltage in a certain proportion. The utility model has the advantages of simple structure, easy installation, low cost and high test precision, etc, which can be widely applied to the locations where the test, control, and record of the angle change are needed.
Description
One, technical field
The utility model relates to a kind of capable angle/electric pressure converter of changing measurement of angle of changing value that utilizes voltage.
Two, background technology
People usually will convert these variable quantities to electric signal, for this reason in order to measure and control the variation of a certain physical quantity, various sensors have been designed, converter, transmitter, these devices all have purposes separately, also do not occur at present for the sensor of measuring the angle of inclination.
Three, summary of the invention
Goal of the invention of the present utility model provides angle/electric pressure converter a kind of simple in structure, easy for installation.
The technical scheme that realizes goal of the invention is to solve like this: comprise a coaxial rotation duplex potentiometer, said coaxial rotation duplex potentiometer is again that the right-hand member by the left end of slide potentiometer and slide potentiometer links to each other with the positive pole of power supply, the right-hand member of slide potentiometer links to each other with the negative pole of power supply with the left end of slide potentiometer, one end of two slide potentiometers slide potentiometer that is connected in series, the Ling Yi Duan And connection of two slide potentiometers is connected with power supply, voltage table of series connection cross-over connection between the sliding point of two slide potentiometers, coaxial rotation duplex potentiometer is fixedly mounted on a block length limit and is parallel on the square shaped steel plate of surface level minor face perpendicular to surface level, on horizontal steel plate, fixedly connected sash weight in the rotating shaft of coaxial rotation duplex potentiometer.
The utility model compared with prior art, angle/electric pressure converter is that the variable quantity with angle is converted to voltage according to a certain percentage.Have characteristics such as simple in structure, easy for installation, with low cost, measuring accuracy height, the occasion that needing to be widely used in measuring, control, recording angular changes.
Four, description of drawings
Fig. 1 is the utility model circuit structure schematic diagram;
Fig. 2 is the potentiometer installation diagram of Fig. 1.
Five, embodiment
Accompanying drawing is a specific embodiment of the utility model
Below in conjunction with accompanying drawing particular content of the present utility model is described further:
With reference to Fig. 1, shown in Figure 2, comprise a coaxial rotation duplex potentiometer 1, said coaxial rotation duplex potentiometer 1 is again by slide potentiometer W
1Left end and slide potentiometer W
2Right-hand member link to each other slide potentiometer W with the positive pole of power supply E
1Right-hand member and slide potentiometer W
2The left end said coaxial rotation duplex potentiometer 1 that links to each other with the negative pole of power supply E be again by slide potentiometer W
1The end slide potentiometer W that is connected in series
2, two slide potentiometer W
1, W
2Ling Yi Duan And connection be connected with power supply E, two slide potentiometer W
1, W
2Sliding point between series connection cross-over connection voltage table V, coaxial rotation duplex potentiometer 1 is fixedly mounted on a block length limit and is parallel on the square shaped steel plate 2 of surface level minor face perpendicular to surface level, on horizontal steel plate 2, fixedly connected sash weight 4 in the rotating shaft 3 of coaxial rotation duplex potentiometer 1.Coaxial rotation duplex potentiometer 1 angle rotatable is β, and the actual anglec of rotation is α, potentiometer W
1The current potential of sliding point is V
1, potentiometer W
2The current potential of sliding point is V
2, V
1=α/β * E; V
2=(β-α)/β * E V=V
1-V
2=2 * α/β * E-E
Can draw the relation curve that the actual anglec of rotation is α and output voltage V E according to this formula, α and VE are linear relationships, that is to say, output voltage E and actual anglec of rotation α are proportionate relationships.When α=β/2, VE=0 illustrates the mid point of the initial point of angle/electric pressure converter at the duplex potentiometer angle rotatable this moment.
When being fixed on potentiometer W on one block length limit, we are parallel on the square shaped steel plate of surface level minor face perpendicular to the horizontal positioned of surface level, sliding point is adjusted to origin position, at this moment, V=0, sash weight is vertical with surface level all the time, if the steel plate run-off the straight, potentiometer has just rotated an angle, angle/electric pressure converter will be exported the positive and negative and big or small direction and the degree that has just reflected the steel plate run-off the straight of the voltage ， Zhe Ma voltage of Yi Ma or plus or minus.Especially use on truck effect more obvious.An applicating example of the present utility model is, utilizes the utility model can also manufacture automobile-used inclination attention device and is installed in the pilothouse, and the driver can clearly understand the angle of inclination of the vehicle body of oneself at any time, or the trailer angle of inclination of advancing.
