Abstract
The utility model relates to a liquid level measuring instrument, more specifically a level sensor with adjustable range, which comprises a float, a liquid level detecting rod and a liquid level sensing signal processing circuit, wherein the liquid level detecting rod is composed of a detecting upper rod and a detecting lower rod; the detecting upper rod is provided with a liquid level upper limit detecting point; the detecting lower rod is provided with a liquid level lower limit detecting point; the height of one of the detecting upper rod and the detecting lower rod can be adjusted, or the height of two detecting rods can be totally adjusted. The utility model has the advantages that the upper limit and the lower limit has larger adjusting range (which can be suitable for change of an inner cavity of a container); the lowest controlling liquid level can be adjusted (such as 25%, 30%, etc. of the inner cavity of the container and the minimum value of the lowest controlling liquid level of the existing products which adopt stainless steel floats can be controlled at 20MM); the upper rod and the lower rod can be adjusted to accurately control the upper limit position and the lower limit position (the precision can reach to 1MM).
Description
One, technical field
The utility model relates to a kind of level gauging instrument, specifically, is the adjustable liquid level sensor of a kind of bound.
Two, background technology
Present widely used level sensing and controller mainly contain 1, bound (single lever-type) on same rod; 2, bar of the upper limit, lower limit is at the double rod type of another root bar; And other form, to fix entirely, product can not be regulated, and can only be suitable for the environment less demanding, that control accuracy is low.
Chinese patent 01279498 provides a kind of liquid level sensor, is applicable to from the container bottom upwards to insert also unresolved the problems referred to above.
Three, summary of the invention
In order to overcome the technical matters that existing liquid level sensor upper and lower limit can not be regulated, the utility model provides a kind of upper and lower limit adjustable liquid level sensor, can carry out upper and lower spacing adjusting according to the variation of container intracavity.
The technical scheme in the invention for solving the technical problem is: it comprises float, level detection bar, level sensing signal processing circuit, the level detection bar is by surveying upper boom and surveying lower beam and form, survey on the upper boom and establish liquid level upper limit sensing point, survey on the lower beam and establish liquid level lower limit sensing point; Survey wherein adjustable-height of upper boom and detection lower beam, or two equal adjustable-heights.Survey upper boom and survey lower beam, also do not get rid of other regulative mode by the screw rod adjusting height that is connected with its spiral, as: stretch by chuck locking, stretch automatically by spring etc.
The beneficial effects of the utility model are: 1, spacing up and down have than wide adjusting range (can adapt to the variation of container intracavity); 2, to minimum control liquid level scalable (, adopting the minimum value of the minimum control liquid level of product of stainless steel float to can be controlled in 20mm at present) as 25%, 30% or the like of container intracavity; 3, upper and lower bar is regulated the bound position (precision can reach 1mm) that can accurately control liquid level.
Can realize by using the adjustable liquid level sensor of this bound: 1, general between the different big small containers of series; 2, be suitable for the high environment for use of control accuracy; 3, satisfy the specific (special) requirements of user to liquid level bound position control.
Four, description of drawings
Accompanying drawing is the utility model structural representation.
Among the figure: adjusted screw rod (1), following adjusting screw(rod) (2), detection upper boom (3), detection lower beam (4), liquid level upper limit sensing point (5), float (6), liquid level lower limit sensing point (7).
Five, embodiment
The utility model is described in further detail below in conjunction with accompanying drawing:
As shown in drawings, it comprises float (6), level detection bar, level sensing signal processing circuit the adjustable liquid level sensor of bound, the level detection bar is made up of height-adjustable detection upper boom (3) and detection lower beam (4), survey on the upper boom (3) and establish liquid level upper limit sensing point (5), survey on the lower beam (4) and establish liquid level lower limit sensing point (7), survey upper boom (3) and survey lower beam (4) by adjusted screw rod (1), following adjusting screw(rod) (2) adjusting height.
Level detection bar of the present utility model also can be surveyed upper boom (3) adjustable-height separately, or surveys lower beam (4) adjustable-height separately.
Float (6), liquid level sensor signal processing circuit are prior art.
Claims (2)
1, the adjustable liquid level sensor of a kind of bound, it comprises float, level detection bar, level sensing signal processing circuit, it is characterized in that: the level detection bar is by surveying upper boom (3) and surveying lower beam (4) and form, survey on the upper boom (3) and establish liquid level upper limit sensing point (5), survey on the lower beam (4) and establish liquid level lower limit sensing point (7); Survey wherein adjustable-height of upper boom (3) and detection lower beam (4), or two equal adjustable-heights.
2, the adjustable liquid level sensor of bound according to claim 1, it is characterized in that: survey upper boom (3) and be connected with adjusted screw rod (1) spiral, survey lower beam (4) and be connected, survey upper boom (3) and survey lower beam (4) by adjusted screw rod (1), following adjusting screw(rod) (2) adjusting height with following adjusting screw(rod) (2) spiral.
