Context
Components and working principle: A liquid level detector is composed of the conductor
outer jacket, liquid level detector, switch, and card pole. A liquid level detector rises or drops
as the liquid level changes due to the magnetism of the liquid level switch, causing the reed
switch chip in the specified position inside the sensor detection pipe to move and send the
contact on/off conversion signal to control the liquid level detector.
The liquid level detector can be maintained only from the front.
