Product introduction

LF602 series adopts magnetic induction technology sensor for liquid level measurement, the signal is processed by the rear processing circuit and converted into standard industrial electrical signal output and display.
Under the action of liquid buoyancy, the floating ball moves up and down along the guide bar, continuously triggering the magnetic switch in the guide bar, which controls the number of resistors turned on or off, converting the liquid level change into resistance change, and the resistance value is converted into a standard electrical signal output and displayed after processing by the rear circuit.
-Full metal housing design
-Liquid crystal digital display enables the series to be used in a variety of industrial applications.
-Two-button design and user-friendly menu make the product more convenient to use.
-A variety of connection options are available to meet specific installation requirements.
-The 330° rotatable display head ensures the best viewing angle in different installation methods.
