Description
Technical field
The utility model relates to a kind of water-temperature water-level sensor, especially a kind of sensor that is used to detect water-temperature water-level in the solar water heater water tank.
Background technology
Water-temperature water-level sensor is arranged in the water tank of solar water heater, is used to detect water temperature and the water level in the water tank.Water-temperature water-level sensor inserts in the water tank from the bottom or the top of water tank; Its structure generally comprises interface end, water-temperature water-level sensing circuit, stainless steel sensor bar and SOI sebific duct; The water-temperature water-level sensing circuit is located in the said interface end, and each stainless steel sensor bar links to each other with the conducting of water-temperature water-level sensing circuit respectively.During connection, each stainless steel sensor bar inserts earlier in the set recess of interface end outside surface, and the colloidal silica that reinjects makes the connecting portion sealing.But use long afterwards, splitting easily and cause into water in the junction, thereby has influenced the operate as normal of water-temperature water-level sensor.And sensor is immersed in the water tank for a long time when using, incrustation easily on the outer wall of stainless steel sensor bar, thus have influence on the sensitivity and the serviceable life of sensor.
Summary of the invention
The utility model technical matters to be solved is to propose the water-temperature water-level sensor of the solar water heater of a kind of good operating stability, highly sensitive, long service life.
For solving the problems of the technologies described above; The water-temperature water-level sensor of a kind of solar water heater of the utility model comprises interface end, water-temperature water-level sensing circuit, stainless steel sensor bar, electric silica gel section and SOI sebific duct; Said water-temperature water-level sensing circuit is located in the said interface end; Said each stainless steel sensor rod seal is plugged on the said interface end; Said each stainless steel sensor bar links to each other with the conducting of water-temperature water-level sensing circuit respectively, and said stainless steel sensor bar comprises a public electrode induction rod and some level electrode induction rods, and said SOI sebific duct is sheathed on respectively on said each level electrode induction rod and with the top of level electrode induction rod and exposes; Both connectivity port sealings, said electric silica gel section are coated on the outside and mutual conduction of said each stainless steel sensor bar respectively.
The water-temperature water-level sensor of above-mentioned a kind of solar water heater, the end face of said interface end is provided with hollow convex column, and said each stainless steel sensor bar inserts each said hollow convex column, outside recycle silicon sebific duct sealing and fixing.
The water-temperature water-level sensor of above-mentioned a kind of solar water heater is coated with some said electric silica gel sections on the said public electrode induction rod, the position of said each electric silica gel section is corresponding with the top of said each level electrode induction rod respectively.
The utility model is owing to adopted technique scheme; After the outside socket electric silica gel section of stainless steel sensor bar; The electric silica gel section also simultaneously as the part of water level induction electrode, had both made working sensor tie incrustation scale on the stainless steel sensor bar long afterwards, and the electric silica gel section still can sense the water level situation; And the stainless steel sensor bar that links to each other through conducting with it is delivered to operating circuit, guaranteed the sensitivity and the stability of working sensor.Stainless steel sensor bar and interface end are fixedly linked through hollow convex column and outside silicone tube, good airproof performance, both made of long duration after infiltration also not easy to crack, thereby prolonged serviceable life of sensor.Be coated with the corresponding some electric silica gel sections of position and each level electrode induction rod on the public electrode induction rod, the water level sensing sensitivity of sensor is higher.
