Product overview
The LBC in-built level controller is a level controller developed by automatic control of liquid level according to use requirements. It is characterized by automatic and precise control of liquid level and has such advantages as no manual operation needed and being stable and reliable. It can be used for automatic control for medium liquid level position of the equipment (including various towers, tanks, grooves, spherical vessels and boilers) in such industries as petroleum, chemical engineering, chemical fertilizer, rubber, medicine, ship, military, electric power and food.
Product features
● Measuring range: 300～6000mm;
● Operating temperature: -40～200℃;
● Control accuracy: ≤±10mm;
● Medium density: ≥0.5g／cm;
● Pressure rating: ≤22MPa;
● Contact power 220V, 100mA;
● Simple structure. The level controller consists of body, float, flange and reed switch.
Operating principle
The liquid pushes the float, the magnet in the float drives the reed switch to suck in and control the intermediate relay, and then the intermediate relay pushes the contactor to control the feed motor to keep the liquid level within a certain range so as to achieve the purpose of automatic control.
