Problem, it is necessary to which a kind of new level sensor is provided.
The content of the invention
In view of the above-mentioned problems, the technical problem to be solved by the present invention is to provide a kind of liquid level sensor.
A kind of liquid level sensor of the utility model, it includes mobile jib, upper cover, inserted sheet, float, and one end of mobile jib is fixed with
Upper cover, is provided with inserted sheet in upper cover, and one end of inserted sheet and mobile jib is mutually clamped, and the other end of mobile jib is plugged in the inner ring of float
On.
Sensor circuit is installed preferably, the mobile jib designs for hollow structure, inside it, the top of mobile jib is set
Have increase space, be internally provided with a square snap ring, in that context it may be convenient to fixed cover, can install in space air locking or
Gluing, the top afterbody of mobile jib are provided with slotted eye, convenient to the reliable grafting of plug-in security, have mistake proofing outside slotted eye
Boss and to plug-in unit anticreep boss.
Preferably, the upper cover is semicircular structure, it is internally provided with boss, can be with the square snap ring of mobile jib
It is connected, the both sides of upper cover are respectively arranged with groove, there can be big circle with the male cooperation of mobile jib, the edge of upper cover
Angle.
Preferably, the inserted sheet selects the material of high conductivity, and hardness is higher, size is wider, can ensure with
The cooperation tight to plug-in unit.
Preferably, being provided with magnet ring in the float, density is smaller and uniform in material, and what can be stablized floats over liquid
Corresponding position.
The beneficial effects of the utility model：After the liquid level sensor assembles, it can be examined in -40 DEG C -120 DEG C of liquid
Survey, to atmospheric pressure, humidity does not have a rigid requirement, HD liquid level sensors detection liquid level position sensitive, accurate, and service life can be big
It is safe voltage that voltage is accessed when 1,000,000 times, use, without installing various protection circuits, is integral after having assembled, can not
Dismounting, it is easy to use, simple without accessory, with installation volume is small, easy for installation, easy to operate, test position is accurate, makes
With long lifespan, it is efficient the advantages that.
Brief description of the drawings：
For ease of explanation, the utility model is described in detail by following specific implementations and attached drawing.
