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
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.
