[0047] The use process of the tank liquid level monitoring sensor provided by the utility model is as follows:

[0048] After the installation mechanism 3 is connected to the tank, the liquid level in the tank is monitored through the sensor probe 1. When the sensor probe 1 needs to be taken out, loosen the hand-tightening bolt 207 and then push the protective sleeve 201 away from the sensor protective shell 101 so that the protective sleeve 201 is separated from the limiting strip 303.

Specifically, Figure 7 As shown, a spring 209 is provided in the slot 202 , and the two ends of the spring 209 are fixedly connected to the connecting plate 203 and the slot 202 respectively. The force of the spring 209 can pull the connecting plate 203 so that the protective sleeve 201 maintains the force of approaching the sensor protective shell 101 .

[0051] The use process of the tank liquid level monitoring sensor provided by the utility model is as follows:

[0052] After the installation mechanism 3 is connected to the tank, the liquid level in the tank is monitored through the sensor probe 1. When the sensor probe 1 needs to be taken out, the protective sleeve 201 is pulled away from the sensor protective shell 101 to separate the protective sleeve 201 from the limit strip 303, and the sensor protective shell 101 is pulled upward to separate the L-shaped mounting frame 301 from the sensor protective shell 101, and the sensor probe 1 can be taken out. During installation, the protective sleeve 201 and the sensor protective shell 101 are plugged together with the L-shaped mounting frame 301, and then the protective sleeve 201 is released.
