Abstract
The invention discloses a photoelectric liquid level meter. The liquid level meter comprises a measurement cylinder (7) and a display panel (1), wherein the measurement cylinder (7) is connected with a detected vessel through a flange; a floater (9) is arranged in the measurement cylinder (7); magnetic steel (8) is arranged in the floater; the liquid level display panel (1) is arranged outside the measurement cylinder, and comprises dichroic plane luminotrons (3) soldered on a circuit board (4), a magneto sensor (5) and an assisted control element (6); the display panel (1) is arranged in an aluminum alloy frame and fixed on the measurement cylinder (7); and the distance between adjacent dichroic plane luminotrons represents a unit length. The liquid level meter controls a contact to contact a connection state to emit light to indicate a liquid level by virtue of magnetism, and has the advantages of photoelectric display, good definition, high accuracy, low failure rate, long service life and low maintenance cost.
Description
Technical field
The present invention relates to a kind of liquid level gauge, be specifically related to the photoelectricity liquid level gauge of the luminous indication of a kind of magnetosensitive semiconductor element control luminotron.
Background technology
At present, the liquid level gauge of liquid level height in the known indication container mainly contains glass plate type, magnetic is turned over ball formula, magnetic float type etc.The clear inadequately wash rice of glass plate type liquid level gauge indication, instrument operator can't read the thing position height of feed bin or flow container the inside when the night work on the spot; Magnetic turn over pillar, magnetic float type magnetic bead demagnetization, wear and tear or polluted after the mess code phenomenon can take place, serviceable life is short, the maintenance cost height.
Summary of the invention
The objective of the invention is: a kind of photoelectricity liquid level gauge is provided, utilize the magnetosensitive semiconductor element to detect the position of measuring the tube inner float ball, and liquid level is indicated in the luminous or red green variable color of control plane luminotron, photoelectric display, sharpness is good, the degree of accuracy height, and failure rate is low, long service life, maintenance cost is few.
Technical solution of the present invention is: this liquid level gauge comprises measures tube and display panel, on the float in measuring tube magnet steel is installed, the display panel of indication liquid level is housed in the outside of measuring tube, this display panel comprises the flat luminous pipe that several are subjected to magneto sensor control, and the distance of adjacent luminotron is represented a unit length.
The display panel of this liquid level gauge is made up of semiconductor element, without any movable mechanical part, when the float in measuring tube rises or descends with liquid level, the semiconductor magneto sensor detect the position of float and the flat luminous pipe controlled on the display panel luminous, the display panel of float bottom shows red, the display panel of buoy upper shows green, can clearly indicate liquid level by change in color like this.
During installation, liquid level gauge is installed in the side or the top of measured container by the flange on the measurement tube; During work, flat luminous pipe sends special bright ruddiness green glow and forms luminous bar code indicator solution position height.
The invention has the beneficial effects as follows:
1, show red green two kinds of different colors along with measured medium thing position changes the photoelectric pole that makes, on-the-spot height of materials adopts photo-electronic directly reading, is all to can read measurement, sharpness height at daytime or night.
2, measuring system and photoelectric display system are isolated fully, and corrosion resistance is strong, anti-various adhesion materials, and good seal performance does not have the demagnetization phenomenon, and long service life can reach more than five times of magnetic turnover panel.
3, can adjust angles of display arbitrarily, the precision temperature effect that is not stressed can be measured high-temperature medium, and measuring accuracy can reach 1cm.
Description of drawings
The present invention is further described below in conjunction with accompanying drawing.
Fig. 1 is a structural representation of the present invention.
Fig. 2 is the display panel circuit theory diagrams.
Among the figure: 1 display panel, 2 clear glasses, 3 double-colored flat luminous pipes, 4 circuit boards, 5 magneto sensors, 6 auxiliary control elements, 7 measure tube, 8 magnet steel, 9 floats.
Embodiment
As shown in Figure 1, this liquid level gauge comprises measures tube 7 and display panel 1, measuring tube is connected with tested container by flange, in measuring tube 7, a float 9 is arranged, magnet steel 8 is installed in float, outside measuring tube, liquid level display panel 1 is housed, display panel 1 comprises double-colored flat luminous pipe 3, magneto sensor 5 and the auxiliary control element 6 that is welded on the circuit board 4, display panel 1 is installed in to be fixed in the aluminum alloy frame again and measures on the tube, and the distance of adjacent double-colored flat luminous pipe is represented a unit length.
Wherein, in the outside of display panel 1 clear glass 2 is installed.
Circuit theory diagrams when magneto sensor K1 does not detect the magnetic force of magnet steel 8, are output as high level as shown in Figure 2, switching tube V1 conducting, and V2 ends, and double-colored flat luminous pipe LED1's is red bright, and green is gone out; When some magneto sensor K1 detect the magnetic force of magnet steel 8, be output as low level, switching tube V1 ends, the V2 conducting, double-colored flat luminous pipe LED1's is green bright, and redness is gone out, and passes through the unidirectional conducting effect of diode D1, make these all display units above display unit all show green, all following display units all show redness.
As mentioned above, when the float 9 in measuring tube 7 rises or descends, rely on the effect of magnetic force, it is red that all downward display units of float are shown, all display units that the height of expression liquid level, float make progress show green, and expression does not have liquid.
Claims (2)
1. photoelectricity liquid level gauge, it is characterized in that: this liquid level gauge comprises measures tube (7) and display panel (1), measuring tube (7) is connected with tested container by flange, in measuring tube (7), a float (9) is arranged, magnet steel (8) is installed in float, outside measuring tube, liquid level display panel (1) is housed, display panel (1) comprises the double-colored flat luminous pipe (3) that is welded on the circuit board (4), magneto sensor (5) and auxiliary control element (6), display panel (1) is installed in to be fixed in the aluminum alloy frame again and measures on the tube (7), and the distance of adjacent double-colored flat luminous pipe is represented a unit length.
