Electronic Liquid Level Switch-LF80A

Product introduction

LF80A electronic level switch detects the water level through the built-in electronic probe, and then the chip processes the detected signals, when judging that there is water, the chip outputs high level 24V or 5V, etc. (PNP type), and when judging that there is no water, the chip outputs 0V. High and low level signals are read by the PLC or other control circuits and drive the pumps and other electrical appliances to work.
Under the action of liquid buoyancy, the float moves up and down along the guide bar, continuously triggering the magnetic switch in the guide bar, which controls the number of resistors on or off, converting the change of liquid level into resistance change, and the resistance value is converted into a standard electrical signal output after processing by the rear circuit.
