Abstract
The invention discloses a liquid level sensor which comprises a liquid container (1) and a liquid indicator (2). The liquid level sensor is characterized in that the liquid indicator (2) comprises an upper limiting switch (3), a lower limiting switch (4), a rod body (9), an adjusting nut (5), a pointer (6), a terminal box (7) and an auxiliary draw rod (8). By means of the technical scheme, the contact-free iron-stained problem can be solved, the sensing accuracy and the reliability of the liquid level sensor are improved.
Description
Technical field
The present invention relates to sensor field, especially a kind of liquid level sensor.
Background technology
Present liquid level detection device includes two kinds on physical construction and electronic induction structure.Its physical construction is to utilize ballottement to answer SEA LEVEL VARIATION, until make contact mechanical switch action, there is the larger problem of influence error in this physical construction formula liquid level induction system, and reliability is low.The electronic level pick-up unit can increase substantially job stability, but each click is fixedly installed on the different liquid levels position that liquid container sets, when liquid level position reaches and during submergence respective electrode position, electric circuit inspection drives during to this induced signal and implements control.The electronic type liquid level detection device exists electrode to be subject to the technical matters of test solution corrosion, corruption, and installs and safeguard the trouble that the aspect all compares.
Summary of the invention
In order to overcome the deficiencies in the prior art, the invention provides a kind of problem of non-contact corrosion and improve induction accuracy and the high liquid level sensor of reliability.
Its technical scheme of the present invention's solution is in order to achieve the above object: a kind of liquid level sensor comprises liquid container and limnimeter table display.The limnimeter table display comprises upper limit, lower limit, the body of rod, armature, setting nut, pointer, terminal box, coil and auxiliary connecting rod.
According to embodiments of the invention, described upper limit position switch, lower position switch and coil are wired on the terminal box.
According to embodiments of the invention, described upper limit position switch pointer and lower position switch are fixed on the auxiliary connecting rod.
According to embodiments of the invention, on the described limnimeter table display scale is arranged.
According to embodiments of the invention, an armature is arranged on the described auxiliary connecting rod.
According to embodiments of the invention, described armature moves in coil.
According to embodiments of the invention, described limnimeter table display becomes coniform.
According to embodiments of the invention, a setting nut is arranged on the described body of rod, regulate the scope of maximum position and minimum lower limit.
According to embodiments of the invention, described terminal box is fixed on the outside of height displaying instrument.
The invention has the beneficial effects as follows: the problem of non-contact corrosion, raising induction accuracy and the high liquid level sensor of reliability.
Description of drawings
Examples of the present invention will be described by way of reference to the accompanying drawings, wherein:
Fig. 1 is structural representation of the present invention;
Fig. 2 is limnimeter table display synoptic diagram of the present invention;
Reference numeral is: 1 is liquid container, and 2 is the limnimeter table display, and 3 is upper limit position switch, and 4 is lower position switch, and 5 is setting nut, and 6 is pointer, and 7 is terminal box, and 8 is auxiliary connecting rod.
Embodiment
Disclosed all features in this instructions, or the step in disclosed all methods or the process except mutually exclusive feature and/or step, all can make up by any way.
Disclosed arbitrary feature in this instructions (comprising any accessory claim, summary and accompanying drawing) is unless special narration all can be replaced by other equivalences or the alternative features with similar purpose.That is, unless special narration, each feature is an example in a series of equivalences or the similar characteristics.
By the described a kind of liquid level sensor of Fig. 1 Fig. 2, comprise liquid container and liquid displayer.Limnimeter table display 2, comprise upper limit position switch 3, lower position switch 4, the body of rod 9, setting nut 5, pointer 6, terminal box 7 and auxiliary connecting rod 8, upper limit position switch 3, lower position switch 4 and coil are wired on the terminal box 7, and upper limit position switch 3, pointer 6 and lower position switch 4 are fixed on the auxiliary connecting rod 8.On the limnimeter table display 2 scale is arranged, a setting nut 5 is arranged on the body of rod 9, regulate the scope of maximum position and minimum lower limit.One armature is arranged on the auxiliary connecting rod 8.Armature moves in coil.Terminal box 7 is fixed on the outside of height displaying instrument 2.Floating drum produces buoyancy in liquid, directly promote the center body of rod 9, on the body of rod 9 tops pointer 6 is housed, and directly indicates liquid level, and the surface is clear, and sighting distance is large, and it is convenient to observe; In addition, center push rod drives auxiliary connecting rod 8 when moving up and down, make the armature on auxiliary connecting rod 8 tops mobile in the coil that the intermediate frequency source forcing is arranged, the voltage of coil changes, and the displacement that floating drum is fluctuated is converted to linear electric weight, makes liquid level change teletransmission to the pulpit.
The present invention is not limited to aforesaid embodiment.The present invention expands to any new feature or any new combination that discloses in this manual, and the arbitrary new method that discloses or step or any new combination of process.
