Abstract

The utility model provides a capacitive water level probe. The capacitive water level probe comprises a capacitive inductive probe which comprises an insulating support rod and a plurality of induction pieces arranged on the insulating support rod at intervals, wherein the induction pieces and the ground form capacitance, and the induction pieces are made of a material which is difficult to oxidize; and the capacitive water level probe further comprises a control device which is in signal connection with the plurality of induction pieces and collects capacitance information between the induction pieces and the ground as well as corresponding information between set capacitance and a water level so as to obtain water level information. The capacitive water level probe has the benefits as follows: the induction pieces are used for inducing the water level, and corrosion-resistant metal materials such as aluminum, copper and the like are adopted for making the induction pieces, so that the probe can be immersed in water for a long time, meanwhile, an electric element is prevented from being scalded and corroded by damp, and the service life of the probe is prolonged.

Description

A kind of condenser type water-level probe
Technical field
The utility model relates to the technical field of measurement, refers more particularly to a kind of condenser type water-level probe.
Background technology
The detection method of current known solar water heater water level, is that the probe with a plurality of electrodes is inserted in water tank and measures water level, and it has following shortcoming: 1, owing to being subject to the impact of high temperature, probe is easily ruined; 2, form the various material expanded by heating coefficients of popping one's head in and be not quite similar, use for a long time, the leakproofness variation that causes popping one's head in, thus the precision of impact probe even can not be measured water level; 3, electronic devices and components (being mainly hygristor) long period of soaking is in water, and very easily corrosion, causes serviceable life short.
Utility model content
The purpose of this utility model is in order to overcome the deficiencies in the prior art, and a kind of condenser type water-level probe is provided.
The utility model is to be achieved through the following technical solutions:
The utility model provides a kind of condenser type water-level probe, this condenser type water-level probe comprises: capacitive sensing probe, described capacitive sensing probe comprises insulating support rod, be disposed on a plurality of sensing chips on described insulating support rod, and described sensing chip is the sensing chip that non-oxidizable material is made, described sensing chip and ground form electric capacity; Also comprise control device, described control device is connected with described a plurality of sensing chip signals, and according to the capacitance information and the electric capacity of setting and the corresponding informance of water level that obtain between sensing chip and ground, obtains water level information.
Preferably, described a plurality of sensing chip spaced set.
Preferably, described control device also comprises and described a plurality of sensing chips pilot lamp one to one, for showing water level information.
The beneficial effects of the utility model are: by adopting sensing chip to respond to water level, because corrosion resistant metal materials such as adopting aluminium, copper is made sensing chip, thus can long period of soaking in water, avoided electrical equipment to be burned simultaneously, and be subject to cargo sweat, improved the serviceable life of probe.
Accompanying drawing explanation
Fig. 1 is the structural representation of the condenser type water-level probe that provides of the utility model embodiment.
Embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein is only in order to explain the utility model, and be not used in restriction the utility model.
Refer to Fig. 1, Fig. 1 is the structural representation of the condenser type water-level probe that provides of the utility model.
The utility model embodiment provides a kind of condenser type water-level probe, this condenser type water-level probe comprises: capacitive sensing probe 10, described capacitive sensing probe 10 comprises insulating support rod 11, be disposed on a plurality of sensing chips 12 on described insulating support rod 11, described sensing chip 12 forms electric capacity with ground, and the sensing chip that described sensing chip 12 is made for non-oxidizable material, also comprise control device 20, described control device 20 is connected with described a plurality of sensing chip 12 signals, and according to the capacitance information and the electric capacity of setting and the corresponding informance of water level that obtain between sensing chip 12 and ground, obtain water level information.
In the above-described embodiments, the condenser type water-level probe that the present embodiment provides forms electric capacity by the sensing chip 12 arranging with ground, when water level arrives the position of different sensing chip 12, sensing chip 12 senses water level, and the capacitance between sensing chip 12 and ground changes, probe obtains the information of water level according to the variation of capacitance, adopt said structure, by adopting sensing chip 12, respond to water level, and sensing chip adopts non-oxidizable material to be made, as: copper, aluminium etc., owing to adopting aluminium, the corrosion resistant metal material such as copper is made sensing chip, so can long period of soaking in water, avoided electrical equipment to be burned simultaneously, and be subject to cargo sweat, improved the serviceable life of probe.
Concrete, described a plurality of sensing chip 12 spaced sets.Thereby make the water level information that obtains more even, and adopt a plurality of sensing chips 12 are set, thereby can obtain more water level information.
Better, described control device 20 also comprises and described a plurality of sensing chips 12 pilot lamp 21 one to one, for showing water level information.Concrete, when certain sensing chip 12 senses water level, pilot lamp 21 is corresponding thereto luminous, thereby makes observer can observe intuitively the information of water level.
By foregoing description, can find out, the condenser type water-level probe that the present embodiment provides forms electric capacity by the sensing chip 12 arranging with ground, when water level arrives the position of different sensing chip 12, sensing chip 12 senses water level, and the capacitance between sensing chip 12 and ground changes, probe obtains the information of water level according to the variation of capacitance, adopt said structure, by adopting sensing chip 12, respond to water level, owing to adopting aluminium, the corrosion resistant metal material such as copper is made sensing chip, so can long period of soaking in water, avoided electrical equipment to be burned simultaneously, and be subject to cargo sweat, improved the serviceable life of probe.
These are only preferred embodiment of the present utility model, not in order to limit the utility model, all any modifications of doing within spirit of the present utility model and principle, be equal to and replace and improvement etc., within all should being included in protection domain of the present utility model.
