Product Description

The ALFK-340 series is based on the principle that the magnetic float rises and falls synchronously with the liquid level. When the magnetic float, along the guide rod, reaches the position where the reed switch is installed, the reed switch is closed or released, and the corresponding digital signal is output. This signal can be directly input to the PLC and flash alarm for automatic level control and alarm. It is matched with the signal converter or input to the PLC to directly drive the 220VAC control circuit for automatic motor and valve control.

System Connection
The output signal of the level switch is connected with PLC and other systems for use. When the user uses the level switch as control and alarm signal, if the control (alarm) loop voltage is greater than 36VAC(DC), the user should equip the switch with a signal converter, which can convert the reed switch signal of the level switch into a relay signal with larger capacity, to ensure the safety and reliability of the level switch and prolong the service life.
