Problems solved by technology

[0002] Most of the water level and temperature sensors used in solar water heaters use resistance type water as a conductor to realize the water level display in the water tank, but because the water is easy to scale after heating, the increase of the resistance value will cause the display to fail
There is also a dry yellow tube type with a magnetic floating ring. Although this device is not afraid of water scaling, it is also afraid of long-term scaling when used in places with poor water quality. The monitor cannot show the water level

Embodiment Construction

[0012] It can be seen from the accompanying drawings that its implementation and working principle is very simple; when there is no water in the water tank, it becomes image 3 state, the floating tube (10) is tilted to one side, and the high-temperature-resistant magnet (14) mounted on the movable plate (8) is separated from the reed switch (7), so the reed switches of the four gears are not attracted. , is in an open circuit state, so the water level sensor gear resistance (3) connected in parallel on the gear reed switch (7) is in a series state, and its resistance value is the total of 4 resistors

[0013] value, so an anhydrous state is displayed on the display screen, and a water-adding signal is sent. When water is added, the water level gradually rises, and the floating tube (10) gradually floats up with the buoyancy of the water. The high-temperature magnet (14) also gradually moves down, and when the high-temperature-resistant magnet (14) entered the first gear reed ...

Abstract

Disclosed is a floating multi-gear water level and water temperature sensor for a solar water heater. A hollow floating tube or floating ball serves as a main apparatus, a connection rod is connected with a movable sheet, a movable hole for fixing the float tube connection rod is formed in the center of the movable sheet, and a high-temperature-resistant magnet is arranged at the lower end of the movable sheet. Water in a water tank only plays a buoyancy role and is irrelevant to scaling. When the floating tube floats, the connection rod moves simultaneously, so that the high-temperature-resistant magnets on the movable sheet move reversely, magnetic induction water level reed tubes are fixed at the corresponding positions of the high-temperature-resistant magnet on the movable sheet on a hollow fixation rod, the number of the reed tubes is accordant with the number of gears, two ends of the reed tubes are welded through high-temperature-resistant leads, the tails of the leads are led out of the tank through the hollow fixation rod to be welded with other elements to be connected with a display screen. The water temperature is measured through a temperature sensor and led into the water tank directly through the hollow fixation rod.

Description

technical field [0001] The invention relates to a sensor device for water level and temperature on a solar water heater, in particular to a floating multi-position solar water heater water level and temperature sensor that is not afraid of scaling or high temperature in an empty tank. Background technique [0002] Most of the water level and temperature sensors used in solar water heaters use resistance type water as a conductor to realize the water level display in the water tank, but because the water is easy to scale after heating, the increase of the resistance value causes the display to fail. There is also a dry yellow tube type with a magnetic floating ring. Although this device is not afraid of water scaling, it is also afraid of long-term scaling when used in places with poor water quality. The display cannot show the water level. Contents of the invention [0003] In order to solve the above shortcomings, the present invention provides a floating multi-position ...
