Abstract
The utility model relates to a multi-hole oil-burning sensor with a capacitor for an automobile, which is suitable for an oil tank of an automobile and is also suitable for a diesel locomotive, a steamship, an oil tank, etc. The utility model is composed of a positive plate electrode, a negative plate electrode, an insulating framework and a circular-pipe-shaped shell, wherein, the insulating framework is clamped between the positive plate electrode and the negative plate electrode, after the insulating framework is wound into a circular cylinder, the insulating framework is arranged inside the circular-pipe-shaped shell. The lower end of the circular-pipe-shaped shell is provided with an opening, and the upper end surface of the circular-pipe-shaped shell is provided with leading-out terminals of the positive plate electrode and the negative plate electrode, and oil holes which are vertically ranged are formed by the positive plate electrode, the negative plate electrode, and the insulating framework between the positive plate electrode and the negative plate electrode. The utility model has the advantages of high reliability, long service life and high precision.
Description
The utility model relates to a kind of automobile with porous type electric capacity fuel sensor, is suitable for automotive oil tank, diesel locomotive fuel tank, steamer fuel tank and oil tank etc.
At present, the automobile fuel oil sensor mostly is float-type transmitter greatly, what variation of oil mass fluctuates the float that floats on the pasta in the fuel tank, and indicate what of oil mass by fuel gage by float lever, slide plate, resistor, the problem that float-type transmitter exists is: float, slide plate, indicator all are slide units, can occur stuck motionless, slide plate and resistor bad contact and " false indication " occur, can not correctly indicate oil mass how much.
The purpose of this utility model provides the high automobile of a kind of reliability height, long service life, precision with porous type electric capacity fuel sensor.
The purpose of this utility model is to realize like this, a kind of automobile porous type electric capacity fuel sensor, it is made up of positive plate, negative plate, insulation framework, circle tube form shell body, insulation framework is clipped in and is wound into cylinder between the positive and negative plate and is placed within the circle tube form shell body, the circle tube form shell body lower ending opening, be provided with the leading-out terminal of positive and negative plate in the circle tube form shell body upper surface, insulation framework between positive and negative plate and positive and negative plate form the oilhole of vertical arrangement.
Principle of work of the present utility model is as follows:
The capacitance that the utility model is based on cond is the function of shape, size, mutual alignment and dielectric specific inductance capacity of its two electrodes, in above-mentioned each parameter any one changes, to cause the respective change of capacitance, and constitute capacitance-type sensor.
The utility model puts it in the fuel tank when using, and fuel oil enters the porous type capacitive transducer by oilhole, when the fuel oil pasta descends, causes the variation of capacitance, and the capacitance signal of its variation is through being gone out the variable quantity of pasta by LED or numeric display after the processing of circuit.
Below in conjunction with drawings and Examples the utility model is further described:
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the section drawing after positive and negative plate and insulation framework are reeled.
Fig. 3 is the partial enlarged drawing of Fig. 2.
By the embodiment shown in Fig. 1-3 as can be known, a kind of automobile porous type electric capacity fuel sensor, it is made up of positive plate 1, negative plate 2, insulation framework 4, circle tube form shell body 5, insulation framework 4 is clipped in and is wound into cylinder between the positive and negative plate and is placed within the circle tube form shell body 5, the circle tube form shell body lower ending opening, be provided with the leading-out terminal of positive and negative plate in the circle tube form shell body upper surface, insulation framework between positive and negative plate and positive and negative plate form the oilhole 3 of vertical arrangement.The material of positive and negative plate is that aluminium is thin.
Advantage of the present utility model is as follows: (1) high reliability: because pasta just changes, directly produce The signal of telecommunication and demonstrate what of oil mass, pasta change and show in the middle of no any activity and sliding-contact zero Parts are so improved reliability. (2) high accuracy: as showing with numeral, every word can show that pasta becomes Change 1-2mm or littler, this is well beyond the requirement of automobile, but oil mass is aobvious in the oil tank of oil depot Show it to be needs. (3) high life: this sensor has adopted oil resisting material, and simple in structure, does not have Movable parts have namely reduced maintenance load, have improved the life-span again.
Claims (2)
1, a kind of automobile porous type electric capacity fuel sensor, it is characterized in that it is made up of positive plate (1), negative plate (2), insulation framework (4), circle tube form shell body (5), insulation framework (4) is clipped in and is wound into cylinder between the positive and negative plate and is placed within the circle tube form shell body (5), the circle tube form shell body lower ending opening, be provided with the leading-out terminal of positive and negative plate in the circle tube form shell body upper surface, insulation framework between positive and negative plate and positive and negative plate form the oilhole (3) of vertical arrangement.
2, sensor according to claim 1, the material that it is characterized by positive and negative plate are that aluminium is thin.
