LG-400 series Floating ball type oil-water interface instrument

LG-400 series

Floating ball type oil-water interface instrument

LG-400 floating ball type oil water interface instrument uses the floating ball to move up and down with the liquid, so as to trigger or release the magnetic spring switch in the pipe, after circuit processing output 4-20mA or other different standard models. With multi-interface measurement (1-6 float), explosion-proof, corrosion resistance, can meet most of the measurement needs. Suitable for all kinds of oil and water mixture liquid level measurement, optional field display.

Performance Features

Performance characteristics:
LG-400 floating ball type oil water interface instrument is the use of floating ball magnet changes with the liquid level, to change the resistance in the connecting rod and the magnetic spring switch composed of pressure division circuit, magnetic spring switch gap is small, the higher the precision. The partial voltage signal can be converted to 0-4-20mA or other different standard models by a converter. Indicator can cooperate with other table head for remote indication, is a simple principle, good reliability of the liquid level indicator!

Application field:
LG-400 floating ball type oil water interface instrument is suitable for water treatment control equipment, electrical industry, Marine hydraulic equipment, hydraulic and hydropower, chemical, petrochemical industry equipment and thermal coal boiler. (For liquid density ≥0.75g/cm³ measurement)
