Problems solved by technology

[0005] The purpose of the present invention is to solve the problems of sensor failure caused by water film and scale in the existing water level sensor and the inaccurate measurement of the water level sensor caused by the swing of the existing water level sensor, and provide a water level sensor with strong independence of the motor head and high water level. The sensor will not swing, and the measurement accuracy is high

Abstract

The invention discloses a water level sensor. The water level sensor includes a metal rod, a base used for fixing the metal rod and an end cap, a plurality of electrode heads are arranged in the axialdirection of the metal rod, the outside of the metal rod is wrapped by a rubber sleeve, the electrode heads are located on the outer side of the rubber sleeve, the upper end of a wire is connected with the electrode heads, the lower end of the wire runs through the base and the end cap, the metal rod is a rigid material and can not swing in water, and the water level measurement accuracy is high.The independence between the electrode heads is strong, when the water level sensor stretches out of the water surface, a water film does not make the adjacent electrode heads connected, water levelmisjudgment is not caused, and the reliability is high.

Description

technical field [0001] The invention relates to the technical field of water level detection of a water tank, in particular to a water level sensor. Background technique [0002] A water level sensor needs to be provided in the solar water tank, and the water level in the water tank is detected by the water level sensor. Most of the existing water level sensors are directly strung together with a plurality of electrode heads through a silicone sleeve. [0003] An existing application number is CN201020628132.6, and the patent name is a utility model patent for a silica gel water temperature and water level meter, which is characterized in that it consists of a public sensing area (1), silica gel (2), a thermistor sensor (3), a first water level sensor (4), the second water level sensor (5), the third water level sensor (6), the fourth water level sensor (7), the wiring area (8) and the sensing line (9), wherein the first water level sensor (4) The distance from the public s...
