Description
Technical field
The present invention relates to liquid level measurement device, be specifically related to a kind of novel liquid level measurement mechanism.
The capacity for liquor technology
When measuring the position of some liquid levels, adopt the mode of non-cpntact measurement formula or semi-contact to measure usually.As the liquid level of measuring in the oil cylinder oil is with infrared ray or ultrasonic measurement.And on multiple motor vehicle or ship, measure the liquid level of fuel tank, what often adopt is that the heavily vertical formula of float is measured.More than these several metering systems a shortcoming is all arranged, measure inaccurate exactly.
Summary of the invention:
The purpose of this invention is to provide a kind of novel liquid level measurement mechanism, it can measure the height of liquid level more accurately.And circuit is simple, and cost is low.
A kind of novel liquid level measurement mechanism of the present invention comprises insulating support, it is characterized in that: be provided with on insulating support with metal upper plate and lower plate that make and that be parallel to each other, upper plate is connected with metering circuit by lead respectively with lower plate.
Described a kind of novel liquid level measurement mechanism, its upper plate are dull and stereotyped, and lower plate is a buckplate, are provided with an aperture at least at the recess of lower plate.It is to avoid the impurity in the liquid to deposit onboard that lower plate is designed to concavo-convex effect, influences measuring accuracy; In the effect that the recess of lower plate is provided with a plurality of apertures is to leak under with the impurity in the liquid.
Described a kind of novel liquid level measurement mechanism, its metering circuit is by fixed capacity Cn, the first adjustable resistance R
1, the first adjustable resistance R
2, the first fixed resistance R
3With the second fixed resistance R, the electric bridge of composition, upper plate 2 and lower plate 3 are formed sensing capacitance Cx, are connected with the side a and b of electric bridge respectively; The A end of electric bridge is connected with AC power AC with A ' end, and the B end of electric bridge is connected with reometer with B ' end.
It is work like this: Cx and Cn, R
1-R
4Form electric bridge, adjust R
1, R
2Make bridge balance, voltage table shows full scale, and promptly oil is filled case, and after the pasta in the fuel tank descended, Cx changed, the electric bridge imbalance, and the reading of voltage table reduces, and by calibration, so just can measure the content of oil in the fuel tank.
The present invention compares with prior art and has the following advantages: structure and circuit are all fairly simple, implement easily, and cost is low, and it is directly installed on by in the container of big sickle liquid, can measure the height of liquid level more accurately, and is simple to operate, measure reliable.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Fig. 2 is metering circuit figure of the present invention.
Embodiment
The present invention is further illustrated below in conjunction with accompanying drawing.
Referring to Fig. 1, two apertures 4 of each recess processing in the lower plate that is shaped as buckplate 3 of making of metal are fixedly mounted on insulating support 1 with being shaped as dull and stereotyped upper plate 2 and lower plate 3, and upper plate 2 and lower plate 3 are parallel to each other;
Referring to Fig. 2, with fixed capacity Cn, the first adjustable resistance R
1, the first adjustable resistance R
2, the first fixed resistance R
3With the electric bridge that the second fixed resistance R forms, the A end of electric bridge is connected with AC power AC with A ' end, and the B end of electric bridge is connected with reometer with B ' end, and upper plate 2 and lower plate 3 are formed sensing capacitance Cx, is connected with the side a and b of electric bridge respectively to get final product.
During use, this device is installed in the fuel tank, lower plate is in the bottom of fuel tank, upper plate is at the top of fuel tank, and the pasta of fuel tank is between two plates, and two plates are equivalent to the two-plate of a capacitor, oil is medium, oil level height difference, the value of electric capacity are also just different, measure the height of the pasta in the fuel tank by the size of measuring electric capacity.
