The utility model has long service life, simple structure and convenient installation, and the electrodes are difficult to form scale.
Description
Technical field
The utility model relates to a kind of sensor, relates in particular to a kind of energy perception liquid level and temperature sensor just that designs for solar water heater specially.
Background technology
Prior art is used for the liquid level and the temperature sensor of solar water heater, and subject matter one is electronic component and sensing probe one, directly enters water tank, and electronic component is among the high-temperature water environment for a long time, accelerated electron element aging and reducing serviceable life; The 2nd, contact with water in order not make electronic component, good sealing property must be arranged, existing sealing way mainly contains with heat-shrink tube, silica gel, epoxy resin etc., and adopts above-mentioned way not long serviceable life.Chinese patent CN2454763 solar water heater temperature liquid level sensor and for example, its structure is made up of casing, water temperature Level Detection oscillatory circuit, three-way pipe and water temperature Liquid level test probe, water temperature Level Detection oscillatory circuit is fixed among the casing, the left port sealing of casing and three-way pipe is joined, the water temperature Liquid level test probe joins by the left port of conduit and three-way pipe, the horizontal saliva of intervalve mouth of three-way pipe is put down slightly downwards and the exhaustion spill pipe joins, and the direct inner screw thread of right output port is fixed on the run-down pipe of solar water heater.Above-mentioned patent mainly still is the problem in serviceable life.The design people once designed a kind of simple in structure, dynamo-electric separation, the liquid level of long service life and temperature sensor.
Summary of the invention
Fundamental purpose of the present utility model is: another long service life is provided, is used for the temperature liquid level sensor of solar water heater, select for the user.
Above-mentioned technical matters of the present utility model is mainly solved by following technical proposals: 1, a kind of temperature liquid level sensor that is used for solar water heater, has liquid level sensor, temperature sensor and the electronic component and the electric wiring that match, it is characterized in that: described liquid level sensor comprises level electrode and public electrode; Level electrode is one group of high-temperature insulation lead of being made by the stainless steel wire that is uneven in length more than three or other metal materials, the bottom of described insulated conductor is a bare conductor, described bare conductor coiled spring-like spiral coil forms certain height difference between the spiral coil of every level electrode; Described temperature sensor is the thermistor that adopts hermetically-sealed construction; Described level electrode is connected with electronic component that is positioned at sensor top and electric wiring respectively with temperature sensor; Described level electrode and temperature sensor outside are with silicone tube or other insulation tube, and the spiral coil of described bare conductor is around silicone tube or other insulation tube outside; Described level electrode and temperature sensor and electronic component and electric wiring link reach with top, are coated with insulating material, and the centre is filled out to dash fluid sealant.
The technical solution of the utility model can also be further perfect, as preferably, is connected with heavy bell in the bottom of sensor.
The technical solution of the utility model is based on:
Level electrode: after electrode is put into water tank, principle according to the water conduction, when the water level in the water tank changed, the resistance value at the water level signal line two ends that are attached thereto also can change synchronously, and different resistance values draws certain water level value by the conversion of instrument.
Therefore, the beneficial effects of the utility model are: because electronic component is positioned at the top of sensor, do not contact water, and through encapsulation process; The temperature sensor thermistor is handled through ring seal separately, and the potential electrode at night of liquid level sensor is terminal directly exposed by plain conductor, need not seal, so its serviceable life is longer relatively, and simple in structure, easy for installation, and electrode is not easy fouling.
Description of drawings
Accompanying drawing 1 is a kind of structural representation of the present utility model;
Embodiment
Below by embodiment also in conjunction with the accompanying drawings, the technical solution of the utility model is further described in detail.
Embodiment:
As shown in Figure 1, the level electrode 3 of liquid level sensor has five to be 31,32,33,34,35, level electrode is the short different stainless steel lead of a group leader, adopt 304 stainless steel wires to make, above-mentioned lead is higher than 100 ℃ Polyvinylchloride with heatproof and wraps up, wire end exposes, and the wire end that exposes is wound with spiral coil 30; Because level electrode is that stainless steel wire is directly used wrapped with insulation, diameter of wire can be thinner like this, can save greatly with the material aspect.4 is temperature sensor, adopts thermistor, carries out the ring seal structure treatment.Be with silica gel sheath 2 at liquid level sensor and temperature sensor outside, spiral coil 30 is positioned at the outside of silica gel sheath.Electronic component and electric wiring 1 are positioned at the top of sensor, are connected with temperature sensor with the level sensing electrode respectively, from the junction and to top, seal with fluid sealant.Be connected with weight 5 in the bottom of sensor, make lead be in plumbness all the time, level measuring is more accurate.
During use, the electronic component and the electric wiring 1 that are positioned at the top of sensor are positioned over outside the solar water heater staving, and link to each other with signal wire; Each level electrode and the temperature sensor of liquid level sensor are positioned in the solar water heater staving.
Claims (2)
