The LLC2 series is a dual-probe, conductive liquid level control designed for OEM equipment and commercial appliance applications. Models are available for fill or drain operation. Transformer-isolated 12 V ac is provided at the probes to prevent electrolysis. A trickle current of less than 1 mA determines the presence or absence of liquid between the probes and common. On adjustable units, the sensitivity adjustment allows accurate level sensing while ignoring foaming agents and floating debris. The LLC2 series printed circuit board is conformally coated to resist moisture and corrosion.

動作

Drain (pump-down mode): When the liquid level rises and touches the high probe, the output relay energizes and remains energized until the liquid level falls below the low probe. The output relay then de-energizes and remains de-energized until the liquid again touches the high probe.

Fill (pump-up mode): When the liquid level falls below the low probe, the output relay energizes and remains energized until the liquid level rises and touches the high probe. The output relay then de-energizes and remains de-energized until the liquid level again falls below the low probe.

特長：

  • Isolated 12 V ac voltage on probes
  • Open PCB design
  • Sensitivity adjustment
  • Conformally coated PCB
