The invention discloses a water level temperature sensor for a solar water heater, belonging to the field of solar energy, wherein the water level temperature sensor comprises a measurement body, an elbow pipe, a balance pipe and a resistor integrator, which are sequentially connected, wherein the measurement body comprises an outer sleeve, a stiffener, six measurement terminals and a temperature sensor; the outer sleeve is a sleeve of which the periphery is provided with a wall and the bottom part is sealed; the outer sleeve comprises six electrode protecting sleeves and seven sections of insulating sealing sleeves; the seven sections of insulating sealing sleeves and the six electrode protecting sleeves are arranged according to an insulating and conducting order; the stiffener is arranged inside the outer sleeve; and the six measurement terminals and the temperature sensor are arranged inside the stiffener. The water level temperature sensor disclosed by the invention comprises the measurement body, the elbow pipe, the balance pipe and the resistor integrator, which are sequentially connected, so that the measured water level, the temperature accuracy and stability can be improved, the service life of the water level temperature sensor is improved and the service life of the water level temperature sensor is prolonged to five years.
Description
technical field [0001] The invention relates to the field of solar water heaters, in particular to a water level temperature sensor for solar water heaters. Background technique [0002] At present, China has become the world's largest producer of solar water heaters, and its annual output is about the sum of all countries in the world. But, the water level temperature sensor that is used for solar water heater is matched with it but is in the stage of research and development always. [0003] The solar water level and temperature sensors currently on the market usually have the following problems: 1. The detection of the water temperature and water level of the sensor is easily affected by the interference of water quality, scale, etc., and the collected data is not accurate enough, which seriously affects the control accuracy of the controller. 2. The sensor needs to work in the water heater tank for a long time. Because the heat of the vacuum tube is large, it transfers ...
