6.5.13 (Optional) Replacing the Liquid Level Detector
Prerequisites
● The liquid level detector needs to be replaced.
● A spare liquid level detector of the same model is available and functional.
● Tool: Phillips screwdriver
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
specied position inside the
sensor detection pipe to move and send the contact
on/o conversion signal to
control the liquid level detector.
The liquid level detector can be maintained only from the front.
