Abstract
The utility model relates to a water level detector for a solar water heater, which is composed of a capacitance probe and a capacitance oscillation circuit, wherein the capacitance probe is composed of a metal pipe or a metal rod and an insulation layer which is wrapped on the metal pipe or the metal rod, wherein the length of the metal pipe or the metal rod and the insulation layer is matched with the height of an inner bag of a water tank of the solar water heater. The capacitance probe is vertically arranged in the inner bag of the water tank of the solar water heater, and the metal pipe or the metal rod and the metal inner layer of the water tank are connected with the input end of the capacitance oscillation circuit by conducting wires. The structure of the utility model is a capacitor essentially; when a water level changes, the capacity of the capacitor also changes; after the change of the capacitor is detected by the capacitance oscillation circuit, the water level can be displayed to control the operation of taking in water. The utility model has the advantages of simple structure, convenient installation, long-term favorable stability and ideal effect.
Description
Technical field
