Description
Technical field
The utility model is related to a kind of control system of solar energy water heater, particularly a kind of applied to solar water heater
Air pressure formula level sensor.
Background technology
The substantially electrode point type that current solar water heater measurement water level is used, using the electric conductivity of water, measures water tank
Water level, because water quality difference is big, water quality good zone conducts current is poor, and measurement is forbidden, although and the region electric conductivity of water quality inferiority
It is good, but there is the phenomenon of easy fouling, also cause electrode point sensor not use.
Other types survey level sensor such as：Float-ball type sensor, which has the easy fouling of ball float, to be blocked；Pressure type sensor is easy
Fouling and clogging；Capacitance type sensor is easily influenceed by vapor；Application in solar water heater field is smaller.
The content of the invention
Technical problem to be solved in the utility model is that there is provided a kind of reasonable in design, survey in view of the shortcomings of the prior art
Measure accurately, not by the solar water heater level sensor of water quality impact.
Technical problem to be solved in the utility model is realized by following technical scheme, and the utility model is
A kind of solar water heater level sensor, is characterized in：Provided with circuit board, circuit board is provided with CPU, letter
Number collecting unit and signal transmitter unit, signal gathering unit are connected by signal wire with CPU input, center
Processing unit output end connects with signal transmitter unit input, the signal gathering unit include air pressure formula sensor and
Electrode point sensor；The electrode point sensor is located at the top of water-heater water tank, is provided with and it in the sidepiece of water-heater water tank
The air chamber of connection, the air pressure formula sensor is connected by breather line with air chamber.CPU is single-chip microcomputer.
The utility model is according to the air in the air chamber being connected with water tank using air pressure formula sensor sensed water level
Pressure size judges that water level is higher, and pressure is bigger, so as to cause the inductance value of the inductance coil in sensor bigger, pass through
Detect inductance value with regard to the water level of water tank can be obtained.Because not contacted directly with water, therefore avoid the influence of incrustation scale.
Technical problem to be solved in the utility model can also further be realized by following technical scheme, described
Solar water heater level sensor in, the electrode point sensor be provided with least one full-water level electrode points.Work as electrode
During point sensor only one of which full-water level electrode points, common electrical limit is used as using inner water tank.
Technical problem to be solved in the utility model can also further be realized by following technical scheme, described
Solar water heater level sensor in, the electrode point sensor is common electrical provided with 2 electrode points, an electrode points
Limit, another electrode points are full-water level electrode points.2 electrode points interruption collection water levels, reduce the incrustation scale that electrical effect is caused, full
On the basic horizontal plane in water tank of water level, scaling is also delayed.
Electrode point sensor is also provided with 3 electrode points, and an electrode points are common electrical limit, and another electrode points is
Low water level electrode point, another electrode points are full-water level electrode points.
Technical problem to be solved in the utility model can also further be realized by following technical scheme, described
Solar water heater level sensor in, the air chamber is the tracheae of top closure, the bottom of tracheae and water-heater water tank
Bottom connection, breather line connects with the top of tracheae.
The utility model gathers the pressure signal of water tank by air pressure formula sensor, is collected in conjunction with electrode points
Full-water level, is sent to CPU, and liquid level conversion is carried out by CPU, and the algorithm is based on substantial amounts of actual measurement number
According to overcoming the influence that environment temperature, water temperature are measured pressure sensor.The data handled well are sent to by signal transmitting unit
The master controller of solar water heater.
Compared with prior art, it is combined air pressure formula sensor with electrode point sensor, using electrode points to pressure
The full scale of force snesor is calibrated, so as to overcome pressure sensor because the problem of pressure change and water level are inaccurate, makes
The level measuring of water heater is not influenceed by water temperature and water quality, and measures accurate.
