LDD series explosion-proof float level switch
Most explosion-proof situationsTank and box liquid levels are full and emptyLiquid level alarm
The LDD series explosion-proof float level switch uses the float to move up and down with the liquid, thereby triggering or releasing the magnetic reed switch in the tube and sending out a switch signal.featuresCompact structure, explosion-proof, easy to install, corrosion resistance,covering most measurement requirements. Suitable forLiquid level alarms for various tanks and boxes, optionalMetal and plastic materials, Normally open and normally closed can be set.
LDDThe explosion-proof float level switch uses the principle of liquid buoyancy. When the float moves up and down due to buoyancy, the magnet on the float connecting rod drives the reed switch in the junction box to perform NC and NO actions. The same principle is applied to the micro switch device. The magnet in front of the micro switch and the magnet at the arm end make mutually repelling movements and push the micro switch to achieve NC/NO action.
