Abstract
The utility model relates to the field of detection technology, in particular to a liquid level detection device for the liquid level detection of a plurality of liquid. The liquid level detection device is provided with a base. A transparent circular pipe shaped container for holding liquid is arranged on the base. The two sides of the transparent circular pipe shaped container are respectively provided with a linear light source and a linear photoelectric sensor. The linear light source and the linear photoelectric sensor are respectively connected with a controller through data wires. The controller is used to control the linear light source to give out light and control the linear photoelectric sensor to work. When transparent liquid is arranged in the transparent circular pipe shaped container, the light given out by the linear light source is condensed after passing through the transparent liquid. The brightness of the light passing through the transparent liquid is higher than the brightness of the light passing through the transparent circular pipe shaped container but not passing through the transparent liquid. Accordingly, the part of the linear photoelectric sensor, corresponding to the position of the transparent liquid, outputs the signal with great amplitude. The output signal of the linear photoelectric sensor is transmitted to the controller. The liquid level position of the transparent liquid can be detected after the signal is processed. The utility model has the advantages of simple structure, convenient operation, fast measurement speed, and high measurement accuracy.
Description
Technical field
The utility model relates to the detection technique field, specifically can be used for the liquid level sensor that multiple liquid levels detects.
Background technology
We know, existing liquid level sensor has in liquid and to place cursoryly, comes the method for indirect detection liquid level position by detecting cursory position, and this method is difficult to practical application for the level detection of small amount of liquid; Also having a kind of is that sensor is placed in the fixed position on container, detecting the method that liquid level reaches predeterminated position, and the position numerical value that this method can not the continuous detecting liquid level.
Summary of the invention
Problem to be solved in the utility model is to overcome the deficiencies in the prior art, and a kind of position of energy continuous detecting liquid level is provided, and is specially adapted to the liquid level sensor that small amount of liquid is checked.
The technical solution adopted in the present invention is:
A kind of liquid level sensor is provided with pedestal, and pedestal is provided with the tubular container of receiving fluids, and the both sides of tubular container are respectively equipped with linear light sorurce and linear photoconductor sensor, and linear light sorurce is connected with controller through data line respectively with the linear photoconductor sensor.
Transparent tubular container described in the utility model can adopt independent existence, also can be used as the liquid level sighting tube of another container and exist, a side that is tubular container is provided with container, tubular container is as the liquid level sighting tube of container, the lower end is connected with container, liquid level sighting tube lower end is connected with another container, another container of this moment can adopt opaque material to make the tun of arbitrary shape, both are mutually indirect, when liquid level was in certain altitude in another container, both kept liquid level to be in equal height.
Controller described in the utility model is made up of linear light sorurce and linear photoconductor sensor control section, linear photoconductor collecting sensor signal part and data computation processing section, the control signal that linear light sorurce and linear photoconductor sensor control section provide, drive linear light sorurce and linear photoconductor working sensor respectively, 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 can be controlled linear light source luminescent by controller, control linear working sensor, when in the transparent tubular container transparency liquid being arranged, the light that linear light sorurce sent, tube wall through transparent tube enters transparency liquid, transparency liquid is in the transparent tube container, produce spotlight effect, light is through behind the transparency liquid, light obtains optically focused, the brightness degree of the light of process transparency liquid is higher than the brightness of not passing through the light of transparency liquid through transparent pipe container, the linear photoconductor sensor site amplitude output signal of responsively corresponding transparency liquid position is big, there is not the linear photoconductor sensor site amplitude output signal at transparency liquid position little, the output signal of linear transducer is sent to control section, through after the signal Processing, promptly can detect the liquid level position of transparency liquid.
The utlity model has that simple in structure, easy to operate, measuring speed is fast, the measuring accuracy advantages of higher.
