Abstract
The utility model relates to the technical field of liquid level detection, in particular to a liquid level detection device applicable to liquid level detection of various liquids. The liquid level detection device is provided with a base, and a transparent tubular container for containing liquid is mounted on the base. The liquid level detection device is characterized in that a linear photoelectric sensor is arranged on one side of the transparent tubular container, a light source is arranged above the opening of the transparent tubular container, the linear photoelectric sensor is connected with a controller via a data line, when the transparent tubular container contains transparent liquid, light emitted by the light source irradiates to the liquid, high-bright lighting area is formed from the liquid surface to the surrounding through reflection and refraction of the liquid surface, the linear photoelectric sensor is irradiated by the light so as to generate corresponding electric signals, and liquid level information is acquired after the electric signals are transmitted to the controller to be in data process, thereby completing detection of liquid level. The liquid level detection device has the advantages of simple structure, convenient operation, fast measurement, high measurement precision and the like.
Description
Technical field
The utility model relates to the level detection technical field, particularly a kind of liquid level sensor that is applicable to that multiple liquid levels detects.
Background technology
We know, existing liquid level sensor, and a kind of is to place cursoryly in liquid, comes the indirect detection liquid level position by detecting cursory position, but this method is difficult to practical application for the level detection of small amount of liquid; Another kind is that sensor is placed in the fixed position on container, reaches predeterminated position to detect liquid level, the position numerical value that this method can not the continuous detecting liquid level.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, a kind of position of energy continuous detecting liquid level is provided, and conveniently is applied to the liquid level sensor that small amount of liquid is checked.
The utility model can reach by following measure:
A kind of liquid level sensor, be provided with pedestal, pedestal is provided with the transparent pipe shape container of receiving fluids, a side that it is characterized in that transparent pipe shape container is provided with the linear photoconductor sensor, transparent pipe shape opening of container top is provided with light source, and the linear photoconductor sensor is connected with controller through data line.
Light source described in the utility model is a pointolite, and pointolite is located at the top of transparent pipe shape opening of container, with the liquid level in the irradiation tubular container.
Transparent tubular container described in the utility model can individualism, also can be used as the liquid level sighting tube of another container and exist, promptly be provided with the liquid level sighting tube and parallel container in liquid level sighting tube one side, the lower end of liquid level sighting tube is connected with container, and this moment, another container can adopt opaque material to make the tun of arbitrary shape.
Controller described in the utility model is made up of linear photoconductor sensor control section, linear photoconductor collecting sensor signal part and data computation processing section, the control signal that linear photoconductor sensor control section provides, drive linear photoelectric sensor work, the linear photoconductor signal of sensor is transferred to signals collecting and partly carries out the data sampling processing, be transferred to the data computation processing section then, the treated data that obtain reacting liquid level position are exported to man-machine dialog interface then or are done other purposes.
The utility model work, when in the transparent pipe shape container transparency liquid being arranged, the illumination that light source sent is mapped to liquid, reflection and refraction action by liquid surface, the liquid level place to around form luminous high-brightness region, the linear photoconductor sensor is subjected to the irradiation of this light, produce corresponding electric signal, electric signal is transferred to controller carry out data processing after, obtain liquid level position information, thereby finish detection, have that simple in structure, easy to operate, measuring speed is fast, the measuring accuracy advantages of higher liquid level position.
Description of drawings:
Fig. 1 shows for a kind of structure of the present utility model.
Embodiment:
The utility model is described in further detail below in conjunction with accompanying drawing.
As shown in the figure: a kind of liquid level sensor, be provided with pedestal 1, pedestal 1 is provided with the transparent pipe shape container 2 of receiving fluids, one side of transparent pipe shape container 2 is provided with linear photoconductor sensor 3, transparent pipe shape container 2 peristomes top is provided with light source 4, linear photoconductor sensor 3 is connected with controller 5 through data line, above-mentioned transparent tubular container 2 can independently exist, also can be used as the liquid level sighting tube of another container and exist, link to each other with another container during as the liquid level sighting tube, both liquid can be communicated, liquid level is in equal height, another container of this moment can adopt opaque material to make the tun of arbitrary shape, light source 4 is located at transparent liquid level sighting tube top, the work that matches of light source 4 and linear photoconductor sensor 3 and transparent tubular container or transparent liquid level sighting tube, above-mentioned controller 5(such as Fig. 2), by linear photoconductor sensor control section 8, linear photoconductor collecting sensor signal part 10, form with data computation processing section 9, the control signal that linear light sorurce and linear photoconductor sensor control section 8 provide, drive linear photoelectric sensor 12, the output signal of linear photoconductor sensor 12 is transferred to signals collecting part 10 and carries out the data sampling processing, be transferred to data computation processing section 9 then, the treated data that obtain reacting liquid level position are exported to man-machine dialog interface then or are done other purposes.
When the utility model uses, in transparent pipe shape container 2 or the transparent liquid level sighting tube liquid is housed; Light source 4 is luminous with power connection, light shines transparent pipe shape container 2 or the transparent interior liquid surface of liquid level sighting tube downwards, because the reflection of liquid level and the effect of refraction, form the high brightness luminescent zone at the liquid level periphery, the irradiation that linear photoconductor sensor 3 is subjected to this high brightness luminescent zone produces corresponding electric signal, electric signal is transferred to controller to carry out obtaining liquid level position information after the signal Processing, thereby finish the detection of liquid level position, above-mentioned controller, light source and linear photoconductor sensor are same as the prior art, this does not give unnecessary details, and the utlity model has simple in structure, easy to operate, measuring speed is fast, the measuring accuracy advantages of higher.
