1、 Product Introduction

Uniformly fix the magnetic spring switch and precision resistor in a sealed non-magnetic guide rod. When the floating ball with a hollow and fixed ring magnet inside floats up and down along the guide rod under the action of liquid buoyancy, the magnetic spring switch changes the resistance value of the circuit under the action of magnetic force. The analysis and processing unit inside the circuit detects this change in resistance value and converts it into a 4-20mA standard signal output, achieving continuous control of the liquid level. The smaller the gap between the magnetic spring switch and the precision resistor evenly distributed, the higher the accuracy and the more accurate the control! The unique circuit design and automatic temperature compensation make the product stable and reliable, and not affected by temperature.
