Problems solved by technology

[0002] Existing solar water heaters have difficulty in accurate detection of water level and water temperature due to the small difference in water level and high water temperature to be detected, which brings certain difficulties to the accurate detection of water level and water temperature. Sub-type and capacitive type have disadvantages such as poor reliability, short life, non-continuous measurement, or insufficient measurement accuracy. Pressure type has high process requirements, high cost and difficult to improve measurement accuracy. cumulative error

Abstract

The invention is relates to a sensing element of water level and water temperature of solar water heater by mounting a metal shift chain composed of a float, a lever and drive rod with the support asthe base in the heater and outside of the water heater, by mounting a suit of gear and rack crosshead driving chains with a common sealed driving axle at both sides of a main frame plate to be set vertically above the support among which a gear rack crosshead driving chain is connected with water level shift chain while another is connected with shift electric signal converting chain to convert the water level variaty to the variaty of resistance value to be used by the automatic controller by wire to make the automatic measurement of water level. The temperature sensing element is mounted onthe support through to the bottom of the water heater to obtain the antomatic measurement of water temperature.

Description

Technical field: [0001] The invention relates to a detection device for the water level and temperature of water stored in a solar water heater water tank. Background technique: [0002] Existing solar water heaters have difficulty in accurate detection of water level and water temperature due to the small difference in water level and high water temperature to be detected, which brings certain difficulties to the accurate detection of water level and water temperature. Sub-type and capacitive type have disadvantages such as poor reliability, short life, non-continuous measurement, or insufficient measurement accuracy. Pressure type has high process requirements, high cost and difficult to improve measurement accuracy. cumulative error. Invention content: [0003] The purpose of this invention is to design a water level and temperature sensor for solar water heaters, which has high sensitivity, sealing isolation and insensitivity to high-temperature hot water and scale, a...
