Abstract
The utility model discloses a water level measuring instrument, which particularly relates to a water level measuring instrument which is suitable for a solar energy water heater. A water level sonde is mounted n the highest water line of a water tank, a water level sensor element, a water level probe and an earth polar are all wrapped up by a packaging cap and packaging filling material. The water level measuring instrument is isolated with water in the water tank, which avoids the erosion of water, and leads the service span and measurement precision of the measuring instrument to be greatly improved.
Description
Technical field
The utility model relates to a kind of instrument of measuring water level, particularly a kind of floodometer that relates to solar water heater.
Background technology
At present, the floodometer that uses in solar water heater generally all utilizes the electric conductivity of water and thermistor as sensing element.But because water quality differs greatly and fouling, especially these elements move under the state of high temperature, high humidity for a long time, often make these electronic sensor parts by etch, not only lack serviceable life, and measuring accuracy are relatively poor, the poor reliability of sensing.
Summary of the invention
The utility model is at deficiency of the prior art, and a kind of higher floodometer of precision that can the waterproof etch is provided.
Technical assignment of the present utility model is achieved in that the water-level probe of floodometer and earth polar all encapsulate, and the level sensor element is not interposing in the water, but all is encapsulated in the probe that places on the water level.Encapsulating material is relatively good, the pliable and tough strong material of sealing property, and energy is high temperature resistant, the material of anti-etch, generally uses silica gel.
The beneficial effects of the utility model are: (1) anti-water logging erosion because the level sensor element does not directly place water, and is encapsulated in the probe good water-proof effect; (2) precision height, less scaling because water-level probe is stainless, so the measuring accuracy height; (3) long service life, because anti-etch of this instrument and precision height, will grow serviceable life relatively; (4) encapsulation technology is simple, and cost is low.
Description of drawings
Fig. 1, the utility model structural representation
Among the figure: water level probe (1), level sensor element (2), encapsulation caps (3), water-level probe (4), earth polar (5), call wire (6), signal transmssion line (7).
Embodiment
The utility model will be further described below in conjunction with accompanying drawing.
The reference structure synoptic diagram, the utility model is made up of water level probe (1), level sensor element (2), encapsulation caps (3), water-level probe (4), earth polar (5), call wire (6) and signal transmssion line (7).Wherein, level sensor element (2) places in the water level probe (1), is sealed in the water level probe (1) by encapsulation caps (3) and encapsulation packing material.Water level probe (1) level is installed on the maximum water level of water tank.Water-level probe (4) and region (5) and call wire (6) coupling part are also all encapsulated by encapsulation caps (3) and encapsulation packing material.
Owing to level sensor element (2) places probe (1), and probe (1) places on the water tank maximum water level, and is sealed with encapsulation caps (3) and encapsulation packing material, so level sensor element (2) can be isolated with water well, can not be subjected to etch.Because water-level probe (4) and earth polar (5) are also sealed by encapsulation caps (3) and encapsulation packing material with the connecting portion of call wire, so this position can not lost by water logging yet, have improved the life-span and the precision of floodometer.
Because floodometer 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 caps (3) 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 measuring instrument 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 from the side opening of water tank, allow earth polar (5) and water-level probe (4) fall in the water in the water tank under the nature in water tank and get final product, water level signal transmission line (7) just can demonstrate water level in the water tank by display.
Claims (4)
1. floodometer, constitute by water level probe (1), level sensor element (2), encapsulation caps (3), water-level probe (4), earth polar (5), call wire (6) and signal transmssion line (7), it is characterized in that water level probe (1) is installed in parallel on the maximum water level of water tank, level sensor element (2) is sealed in the water level probe (1) by encapsulation caps (3) and encapsulation packing material.
2. floodometer according to claim 1 is characterized in that the connecting portion of water-level probe (4), earth polar (5) and call wire, by encapsulation caps (3) and the sealing of encapsulation packing material.
3. according to claim 1,2 described floodometers, it is characterized in that encapsulation caps (3) and encapsulation packing material are silica gel.
4. floodometer according to claim 1 is characterized in that water-level probe (4), earth polar (5) are stainless steel materials.
