Abstract
The utility model discloses a liquid level sensor with a stainless steel shell, which is characterized in that a stainless steel hollow sphere and a stainless steel inner wire joint are welded together, and a mercury tilt switch is encapsulated in the stainless steel inner wire joint by waterproof encapsulating glue. Therefore, one end of the stainless steel inner wire joint plays a role of a heavy hammer, and when the stainless steel hollow sphere changes up and down along with the change of the liquid level, the height of one end of the stainless steel inner wire joint is kept unchanged, so that the liquid level signal is transmitted by the mercury tilt switch. The liquid level sensor can resist high temperature and corrosion, is convenient to install and has high liquid level precision.
Description
Technical Field
The utility model belongs to a sensor for collecting liquid level signals, in particular to a liquid level sensor of a stainless steel shell.
Background
The existing liquid level sensors are various, liquid pressure is transmitted into voltage or current signals, resistance value change is tested through liquid conductivity, a reed switch obtains a switch signal through a magnet, and liquid buoyancy and element device gravity are used for acquiring liquid level high and low signals.
In the market, a sensor for acquiring liquid level signals by utilizing liquid buoyancy and element gravity generally adopts a floating ball with a plastic shell, a small ball is arranged in the sensor, and a switching signal is given according to direction change caused by liquid level change. In order to ensure the moving direction of the floating ball, a heavy hammer is often connected to the connecting line.
The plastic floating ball is usually suitable for liquid at normal environmental temperature and cannot be suitable for high-temperature liquid. The distance between the serially connected weights directly affects the accuracy of the water level control.
Disclosure of Invention
In order to solve the above problems, the present invention provides a novel liquid level sensor, which aims to expand the application range and improve the control precision.
In order to achieve the purpose, the technical scheme of the invention is as follows: the utility model provides a level sensor of stainless steel casing, includes that the hollow spheroid of stainless steel, stainless steel internal thread connect, mercury tilt switch, wire, waterproof pouring sealant, outer silk end cap, its characterized in that: the mercury tilt switch is fixed in the sealed cavity by waterproof pouring sealant, and a lead connecting the two connectors of the mercury tilt switch penetrates through the outer wire plug.
Preferably, the plug with the outer wire is replaced by a plug without the outer wire, a cap.
Preferably, the stainless steel inner wire fitting is replaced with a stainless steel outer wire fitting or a length of stainless steel tubing.
Preferably, a small steel ball or a steel block is arranged in a sealing cavity formed by the outer wire plug, the stainless steel inner wire connector and the stainless steel hollow sphere.
The invention has the beneficial effects that: realize high temperature resistant corrosion-resistant problem through stainless steel casing, guarantee the direction of floating and sinking with the welding of stainless steel internal thread joint on the hollow spheroid of stainless steel, realize the quick transmission of water level signal through mercury slope switch, improve level sensor's precision.
