[0002] The liquid level sensor (static pressure level gauge / level transmitter / level sensor / ) is a pressure sensor that measures the liquid level. The static pressure immersion level transmitter (level gauge) is based on the principle that the static pressure of the measured liquid is proportional to the height of the liquid. It uses foreign advanced isolated diffused silicon sensitive elements or ceramic capacitor pressure sensitive sensors to convert static pressure into electrical signals, which are then temperature compensated and linearly corrected.

[0003] The bottom of the liquid level sensor is threadedly connected to the fixing part through a connecting thread tube. When the liquid level sensor is subjected to external force, under the action of the lever, a large force will be transmitted to the connecting thread tube and the fixing part, which may easily cause the connection between the connecting thread tube and the fixing part to loosen or break, affecting the stability of the installation of the liquid level sensor. In order to solve the above problem, the present application proposes a liquid level sensor with good installation stability. Utility Model Content
