Background

The liquid level alarm sensor is applied as follows: a liquid level alarm sensor (and high/high alarm) is required for each cargo tank (tank). The working principle is as follows: when the liquid level rises to a set alarm position (namely the fixed position of a reed switch in the liquid level alarm sensor), the magnetic floating ball senses the reed switch at the position, and the reed switch is normally opened to be normally closed at the moment, so that a signal is output to an alarm system to tell an operator that the cabin (tank) needs to be stopped from being filled with liquid continuously. The alarm system is important for cargo tanks, and it is necessary to detect whether the level alarm sensor is functioning properly before filling the tank. In the detection method (under the empty cabin condition) of the liquid level alarm sensor in the current market, a pull rod is utilized to pull a magnetic floating ball to the position of a reed switch in a sensor, so that the liquid level alarm sensor is triggered and an alarm signal is output, but the existing design has two problems: 1. when a tester pulls a rod, the rod moves up and down, so that sealing between the outside of the cabin and the inside of the cabin cannot be realized, and therefore dangerous gas in the cabin is sprayed out of the cabin (particularly flammable, explosive and toxic liquid goods such as an oil cabin, a chemical cabin and the like), great harm is caused to operators and even surrounding personnel, the operators and the surrounding personnel are easily in extreme danger, and the safety is poor; 2. due to the design, the reed switch in the liquid level alarm sensor cannot be effectively fixed, and relative displacement of the reed switch in the liquid level alarm sensor can be easily caused along with vibration, so that the liquid level alarm sensor fails and is poor in use effect.
