Abstract
The utility model discloses a water level sensor, in particular to a water level sensor which is suitable for solar energy water heaters. The water level sensor adopts a packaging cannula with a drainage hole to pack a hollow-pipe shaped water level probe and an earth polar. The water level sensor not only avoids water from immersing connecting points, improves the service span, but also can accurately measure water levels, and improves the precision.
Description
Technical field
The utility model relates to a kind of instrument of measuring water level, particularly a kind of level sensor that relates to solar water heater.
Background technology
At present, the level sensor that uses in solar water heater generally all utilizes the electric conductivity of water and thermistor as the sensing components and parts.But, because most of level sensors all are sealed thermistor and level electrode signal wire, and in case poorly sealedly have water to immerse, even water level reduced in addition water tank in do not have under the situation of water, still be immersed in the water water level mistake that causes level sensor to show owing to be sealed in the inside level electrode.
Summary of the invention
The utility model is at deficiency of the prior art, and a kind of sensor that can the measure water position is provided.
Task of the present utility model is achieved in that each water-level probe and the earth polar of level sensor, and the junction of itself and call wire all encapsulates with package tube; Between each water-level probe, and on the package tube between water-level probe and the earth polar, all have osculum; Water-level probe is a hollow pipe type.
The beneficial effects of the utility model are: (1) precision height, owing to have osculum on the package tube, water-level probe is a hollow tubular, and when water level reduced, water will be discharged from osculum, and is dirty or ooze out from hollow tubular, not induction that can be wrong and demonstration water level; (2) long service life, because water-level probe and call wire junction seal, water can the etch level sensor and influence serviceable life; Because the many places encapsulation connects, strengthened the intensity of product simultaneously.(3) technology is simple, and cost is low; (4) attractive in appearance.
Description of drawings
Fig. 1, the utility model structural representation
Among the figure: water level probe (1), encapsulation sleeve pipe (2), osculum (3), water-level probe (4), earth polar (5).
Embodiment
The utility model will be further described below in conjunction with accompanying drawing.
With reference to the utility model structural representation.The utility model encapsulates sleeve pipe (2) by water level probe (1), osculum (3), and water-level probe (4) and earth polar (5) are formed.Wherein, water level probe (1) is installed on the maximum water level of water tank, and water-level probe (3) all links to each other with call wire with earth polar (4), and its junction all has encapsulation sleeve pipe (2) to encapsulate.Owing to have osculum (3) on the encapsulation sleeve pipe (2), so, when decline of water table, water in the package tube (2) also can pass through osculum (3) and correspondingly discharge, make water-level probe (4) can water-level probe (4) and water be connect, and then send the water level shows signal mistakenly because of encapsulating sleeve pipe internal memory water.Because water-level probe (4) is vasiform,, can also flows down, ooze out again by the hollow of water-level probe (3) even the osculum (3) on the encapsulation sleeve pipe (2) is unclean the water row of encapsulation sleeve pipe (2) lining.Like this, no matter be that water level rises or descends in the water tank, water-level probe (4) all can accurately show real water level, and transmits water level electric signal accurately to water level probe (1), make level sensor more accurately, safety.Because water-level probe (4) and earth polar (5) all have encapsulation sleeve pipe (2) to seal with the connecting portion of call wire, so this position can not lost by water logging, simultaneously also increase intensity, and improved the measuring accuracy and the mission life of level sensor, increased aesthetic feeling.
Because level sensor is generally equipped again after solar water heater is installed,, also certain pliability must be arranged, and get easy and simple to handle so want tight when not only requiring encapsulation.So encapsulation sleeve pipe (2) and encapsulation packing material generally use silica gel.
Because the pH value difference of China's various places water quality, amount and composition impure in the water are different, are the life-span of the sensor of flooding, and stainless steel material is generally adopted in water-level probe (4), earth polar (5).
During use, water level probe (1) level is inserted in water tank and fix, allow earth polar (5) and water-level probe (4) in water tank, fall under the nature in the water in the water tank and get final product from the side opening of water tank.
Claims (3)
1, a kind of level sensor by water level probe (1), encapsulation sleeve pipe (2), osculum (3), water-level probe (4) and earth polar (5) formation, is characterized in that encapsulating and has osculum (3) on the sleeve pipe (2), and water-level probe (4) is vasiform.
2, level sensor according to claim 1 is characterized in that encapsulating sleeve pipe (2) and the sealing inserts is a silica gel.
3, level sensor according to claim 1 is characterized in that water-level probe (4), earth polar (5) are stainless steel materials.
