Electronic digital liquid level switch sensor-LF602

PREV: Anti-corrosion electronic liquid level switch sensor-LF601
NEXT: Electronic liquid level display temperature integrated switch sensor-LF60C

Product introduction

Principle and Features: The LF602 series adopts a magnetic induction technology sensor for liquid level measurement. The signal is processed by the rear processing circuit and converted into a standard industrial electrical signal output and display.
Under the buoyancy of the liquid, the float moves up and down along the guide rod, continuously triggering the magnetic switches in the guide rod. The magnetic switches control the number of resistances that are turned on or off, converting the liquid level changes into resistance changes. The resistance value is then processed by the rear circuit and converted into a standard electrical signal output and display.

Full metal housing design
Uses LCD digital display, enabling this series of products to be used in various industrial applications.
Dual-key design and user-friendly menu make the product easier to use.
Multiple connection methods can fully meet various specific installation requirements.
A display head that can be rotated 330° ensures the best viewing angle under different installation methods.
