Introduction

principle

LV21 series general-purpose side-mounted liquid level switches are switch output type. When the liquid level rises or falls, it drives the stainless steel magnetic float to move up and down, and the reed switch (or micro switch) in the junction box interacts with the magnet at the arm end to cause the reed switch (or micro switch) to act. At the same time, it outputs on (ON) or off (OFF) signal for alarm prompt or remote control.

application

For liquid level measurement with liquid density ≥0.65g/cm3.

It is used for liquid level measurement in ships, water treatment, food, medicine, chemical and other industries.

Features
