Abstract
The utility model relates to a novel liquid level sensor comprising a rod body and at least two floating balls. The floating balls are sleeved on the outer part of the rod body, and position-restricted sheets are disposed on the upper side and the lower side of each floating ball. At least two Hall sensors are disposed in the rod body, and each Hall sensor is disposed correspondingly to one floating ball. The Hall sensors are connected with an external processor through signal lines. In the novel liquid level sensor provided in the utility model, a plurality of floating balls and a built-in Hall sensor are integrated in one liquid level sensor. The novel liquid level sensor can be used for measuring the liquid levels of various liquid, and by using the utility model, the different liquid levels such as less, normal, and full liquid in the container can be detected conveniently and stably. The utility model has advantages of stable structure, low costs, and applicability of being used in many industries such as petroleum chemical industry, metallurgy, electric power, pharmacy, water supply and environmental protection having requirements of measuring the liquid level.
Description
Technical field
The utility model relates to a kind of novel liquid level sensor.
Background technology
Existing liquid level sensor has magnetic reprint, ball float, throw-in type, ultrasound wave, magnetic induction etc. multiple, can select corresponding sensor according to different range demands, degree of protection, container pressure, mode signal output etc.
A lot of application scenarios need be measured liquid and whether arrive certain position, available float-ball type sensor, but the float-ball type sensor can only be measured two different fluid level condition.According to system's actual demand, many times same container domestic demand is measured a plurality of fluid level condition, lacks liquid, normal, the full three kinds of fluid level condition of liquid of liquid level as liquid in the need measuring vessel, three float-ball type sensors then is installed, the mounting structure complexity.If adopt accurate measurement formula liquid level sensor, cost is often higher.
The utility model content
Problem such as liquid level sensor mounting structure complexity, use cost height when measuring a plurality of liquid level information in order to solve above-mentioned prior art, the utility model provides a kind of novel liquid level sensor, easy for installation, Stability Analysis of Structures, with low cost can conveniently detect the sensor of two and above liquid level information.
The technical scheme that the utility model solves the problems of the technologies described above is as follows: a kind of novel liquid level sensor, it comprises the body of rod and at least two ball floats, described ball float is sleeved on body of rod outside, and the upper and lower of each ball float is provided with banking stop, be provided with at least two hall sensors in described body of rod inside, and each hall sensor is corresponding with a ball float position, and described hall sensor is connected with ppu by signal wire.
Further, rubber ring and set bolt are housed also on the described body of rod, and rubber ring and set bolt are arranged on the top of described at least two ball floats.
The beneficial effects of the utility model are: the utility model novel liquid level sensor is integrated into several ball floats and built-in hall sensor in the liquid level sensor, being mainly used in various liquid levels measures, can make things convenient for, lack different liquid levels such as liquid, normal, full liquid in the stable detection receptacle, Stability Analysis of Structures, with low cost, needing can be used for all conglomeraties such as petrochemical complex, metallurgy, electric power, pharmacy, water supply and sewage, environmental protection of level gauging.
Description of drawings
Fig. 1 is the structural representation of the utility model novel liquid level sensor.
In the accompanying drawing, the list of parts of each label representative is as follows:
1, the body of rod, 2, ball float, 3, hall sensor, 4, set bolt, 5, signal wire, 6, rubber ring, 7, banking stop.
Embodiment
Below in conjunction with accompanying drawing principle of the present utility model and feature are described, institute gives an actual example and only is used to explain the utility model, is not to be used to limit scope of the present utility model.
As shown in Figure 1, a kind of novel liquid level sensor, it comprises the body of rod 1, be set with set bolt 4, rubber ring 6 and three ball floats 2 from top to bottom successively in the body of rod 1 outside, the upper and lower of each ball float 2 is provided with banking stop 7, and each ball float 2 limits the scope that fluctuates by banking stop 7, is provided with three hall sensors 3 in the body of rod 1 inside, and each hall sensor 3 is corresponding with the position of a ball float 2, and hall sensor 3 is connected with ppu by signal wire 5.
Each Hall element is provided with two signal wires 5, one of them signal wire of each Hall element is connected the back as the global semaphore line with a signal wire of other Hall elements, and be connected with ppu, another signal wire is drawn the back separately and is connected with ppu.
The utility model novel liquid level sensor and container are fixed by set bolt, and built-in rubber ring can make the container that this liquid level sensor is installed keep airtight.
According to liquid corrosion and potential of hydrogen, rubber ring may be tailored to the rubber of different model specification.
The utility model novel liquid level sensor can may be tailored to different materials such as stainless steel, engineering plastics according to characteristics of liquids and cost with the liquid contacting part branch.
The utility model novel liquid level sensor is integrated into several level sensing ball floats and built-in hall sensor in the sensor, can make things convenient for, stable different liquid level information such as lacking liquid, normal, full liquid in the container be passed to ppu.
The liquid level number that the ball float number of the utility model novel liquid level sensor and the number of corresponding built-in hall sensor can be measured is as required determined.
The utility model novel liquid level sensor causes that by liquid level change the ball float upper-lower position changes, and then hall sensor records several groups of respective switch amount signals, can determine liquid level according to several groups of switching value signals.
The above only is preferred embodiment of the present utility model, and is in order to restriction the utility model, not all within spirit of the present utility model and principle, any modification of being done, is equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
