Abstract
The utility model relates to an electrode-type water temperature and level sensor, which is provided with a common electrode and a temperature testing element on a rod-shaped insulating casing and a bottom end. A group of water level electrodes is arranged on a rod body, and an inner cavity of the insulating casing is filled with the filling material of epoxy resin and is provided with reinforcing ribs. The utility model solves the puzzles of technology and technique of the electrode-type water temperature and level sensor, such as high temperature resistance, corrosion resistance, thermal expansion and cold shrinkage, sealing performance, etc. The utility model can be widely used in the technical fields, which need water temperature and level display and control, such as solar water heaters, electric water heaters, washing machines, etc.
Description
The utility model relates to a kind of water-temperature water-level sensor, relates in particular to a kind of solar water heater electric pole type water-temperature water-level sensor.
At present, it is various in style to be used for the sensor of water-temperature water-level display, controller.Roughly be divided into two classes: a class is mechanical floats formula (as No. 92214534.2, Chinese patent); One class is electric pole type (as No. 96242181.2, Chinese patent).The corrosion of mechanical floats Shi Duoyin guide rod, incrustation and block malfunctioning.Electric pole type many because of electrode corrosion, incrustation, contact conductor short circuit, open circuit, leak and lost efficacy.Finally cause display, controller product cisco unity malfunction.Through preliminary search, do not find that as yet the electric pole type water-temperature water-level sensor that is used in solar water heater water-temperature water-level display, the controller is seen in patent disclosure.
The purpose of this utility model provides a kind of electric pole type water-temperature water-level sensor, it have high temperature resistant, anticorrosive, thermal expansivity is little, the characteristics of good seal performance.
The purpose of this utility model is achieved in that the public electrode that places bottom in the rod insulation crust is electrically connected with copper sheet pin and public electrode lead-in wire, temperature element one end near public electrode is electrically connected with public electrode, and the other end is connected with the temperature element lead-in wire; One group places the level electrode on the rod insulation crust all to be electrically connected with its corresponding copper sheet pin and contact conductor; All contact conductors import outgoing cable.Be full of the epoxy resin filler in insulation crust, the cable exit secures with silicone rubber for sealing.
Owing to adopt such scheme, have high temperature resistant, anticorrosive, thermal expansivity is little, the characteristics of good seal performance, and simple in structure.
Below in conjunction with drawings and Examples the utility model is further specified:
Fig. 1 is circuit theory diagrams of the present utility model.
Fig. 2 is the longitudinal profile structural map of the utility model embodiment.
1. insulation crusts, 2. copper sheet pins, 3. temperature elements, 4. temperature elements, 5. public electrodes, 6. public electrodes, 7. level electrodes, 8. level electrodes, 9. level electrodes, 10. level electrodes, 11. silicone rubber for sealing, 12. outgoing cables, 13. resin extenders, 14. reinforcements, 15. vent ports that go between that go between among the figure
In Fig. 1, temperature element (3) is contacted mutually with public electrode (5), and temperature element lead-in wire (4), public electrode lead-in wire (6) and one group of level electrode lead-in wire import cable (12).
In embodiment shown in Fig. 2, a kind of electric pole type water-temperature water-level sensor is made of temperature element (3), public electrode (5), one group of level electrode (7,8,9,10), insulation crust (1) and sensor outgoing cable (12).Place the public electrode (5) of the interior bottom of rod insulation crust (1) to be electrically connected with copper sheet pin (2) and public electrode lead-in wire (6), temperature element (3) one ends near public electrode (5) are electrically connected with public electrode (5), and the other end is electrically connected with temperature element lead-in wire (4).One group places the level electrode (7,8,9,10) on the rod insulation crust (1) all to be electrically connected with its corresponding copper sheet pin and contact conductor.All contact conductors all import outgoing cable (12).Being full of epoxy resin filler (13) cable exit in insulation crust (1) secures with silicone rubber for sealing (11).For improving the electrode corrosion-resistant performance, all electrodes all adopt stainless steel electrode.Go up a vent port in addition, exhaust during in order to the filling epoxy resin filler at insulation crust (1).Also put a reinforcement (14) to improve the sensor rigidity at insulation crust (1) inner chamber.
Claims (2)
1, a kind of electric pole type water-temperature water-level sensor has temperature element (3), public electrode (5), one group of level electrode (7,8,9,10), insulation crust (1) and sensor outgoing cable (12); It is characterized in that: place the public electrode (5) of the interior bottom of rod insulation crust (1) to be electrically connected with copper sheet pin (2) and public electrode lead-in wire (6), temperature element (3) one ends near public electrode (5) are electrically connected with public electrode (5), and the other end is electrically connected with temperature element lead-in wire (4); One group places the level electrode (7,8,9,10) on the rod insulation crust (1) all to be electrically connected with its corresponding copper sheet pin and contact conductor; All contact conductors all import outgoing cable (12), and the cable exit seals with silicon rubber (11); In insulation crust (1), be filled with epoxy resin filler (13).
2, electric pole type water-temperature water-level sensor according to claim 1, it is characterized in that: described each electrode all adopts etch-proof stainless steel electrode, all electrical connections all are sealed in the interior epoxy resin filler of insulation crust (1), one vent port (15) is arranged on insulation crust, put reinforcement (14) at the inner chamber of insulation crust (1).
