Abstract
The utility model discloses an induction electrode of a water temperature and level sensor, including a stainless steel induction tube and a conductive silica gel section, and the conductive silica gel section is enclosed outside the stainless steel induction tube and is conducted with the stainless steel induction tube. The induction electrode of the water temperature and level sensor provided has the advantages of good work stability, high sensitivity, and long service lifetime.
Description
Technical field
The utility model relates to a kind of inductive means of water-temperature water-level sensor, the induction electrode of water-temperature water-level sensor in specifically a kind of solar water heater water tank.
Background technology
Water-temperature water-level sensor is arranged in the water tank of solar water heater; Be used to detect water temperature and the water level in the water tank; Its structure generally comprises water-temperature water-level sensing circuit, induction electrode and silica gel section etc.; Induction electrode generally adopts the stainless steel sensor pipe, and stainless steel sensor pipe spacer sleeve also is connected with circuit respectively in water-temperature water-level sensing circuit outside.In the use, owing to be immersed in the water tank for a long time, incrustation easily on the outer wall of stainless steel sensor pipe, thus have influence on the sensitivity and the serviceable life of sensor.In addition, because the tracerse point of water-temperature water-level sensing circuit is welded on the inwall of stainless steel sensor pipe, spot welding place is easy to by corrosion; Use is prone to long afterwards penetrate and leaks; Easy and the stainless steel spot welding place corrosion disconnection of circuit signal line, water level signal can't be responded to, thereby influences the normal use of sensor.
Summary of the invention
The utility model technical matters to be solved is to propose that a kind of working stability is reliable, highly sensitive, the induction electrode of the water-temperature water-level sensor of long service life.
For solving the problems of the technologies described above, the induction electrode of a kind of water-temperature water-level sensor of the utility model comprises stainless steel sensor pipe and electric silica gel section, and said electric silica gel section is coated on the outside and mutual conduction of said stainless steel sensor pipe.
The induction electrode of above-mentioned a kind of water-temperature water-level sensor, it also includes the copper pipe section, and said copper pipe section is fixed on the inwall and the mutual conduction of said stainless steel sensor pipe, and the lead of said water-temperature water-level sensing circuit links to each other with the inwall conducting of said copper pipe section.
The utility model is owing to adopted technique scheme; After the outside socket electric silica gel section of stainless steel sensor pipe; 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 pipe long afterwards, and the electric silica gel section still can sense the water level situation; And the stainless steel sensor pipe that links to each other through conducting with it is delivered to operating circuit, guaranteed the sensitivity and the reliability of working sensor.After the stainless steel sensor pipe liner copper pipe section, the lead of water-temperature water-level sensing circuit does not just link to each other with the spot welding of stainless steel sensor inside pipe wall, links to each other and change with the inwall conducting of copper pipe section.Like this, just there is not solder joint on the stainless steel sensor pipe, thereby is difficult for corrosion yet, prolonged the serviceable life of sensor.
