Description
Technical field
The utility model belongs to solar hot-water engineering liquid level float ball sensor, belongs to sensor technical field.
Background technology
The liquid level sensor of using in the known solar hot-water engineering adopts pressure type liquid level sensor or liquid level float ball sensor more.The pressure-sensitive diaphragm temperature resistant range of pressure type liquid level sensor is low, and temperature is floated greatly, be unsuitable for being installed in outdoor, and resistive connection dirt, poor anti jamming capability; Single resistance is indefinite in the circuit design of liquid level float ball sensor, and the used resistance of different liquid levels is different with quantity, causes the sensor circuit complex structure, makes loaded down with trivial detailsly, lack of standardization, and error is bigger.
Summary of the invention
In order to overcome the defective that existing sun engineering level sensor exists, the purpose of this utility model provides a kind of solar hot-water engineering liquid level sensor, and it is less scaling, antijamming capability good, simple in structure, the accuracy of detection height.
The utility model adopts following technical scheme, this kind solar hot-water engineering liquid level sensor, comprise sensor outer housing and circuit package, the sealing of sensor outer housing port is on end cap, drawing lead is connected on the circuit package by end cap, it is characterized in that, be provided with the circuit of forming by a plurality of resistance and the tongue tube of fluid sealant sealing in the described circuit package, between circuit package and the sensor outer housing by the sealing of port sealing glue; Be nested with magnetic float on sensor outer housing, magnetic float internal fixation one is nested with the magnetic on sensor outer housing.
Adopt fixing resistance value, the resistance of fixed qty, the size of resistance value and the linear ratio of tested liquid level in the sensor in the different liquid level circuit package.Make the consistance of described sensor better like this than common sensor.
Described sensor outer housing, magnetic float shell all adopt stainless steel.
When magnetic float during with liquid level change, magnetic float moves up and down, when a certain position, magnetic in the magnetic float makes a certain reed switch conduction, thereby make sensor that a fixing resistance value be arranged, because of the size and the linear ratio of tested liquid level of the resistance value of sensor, so can represent the height of tested liquid level by the size of resistance value.
The utility model beneficial effect is: simple in structure, make simple and easy, easy for installation, accuracy of detection height, the economic use.
