系列: LLC2

The LLC2 series is a dual-probe, conductive liquid level control designed for OEM equipment and commercial appliance applications. 可提供用于灌装或排水操作的型号。 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.在可调装置上，敏感度调节可实现精确的液位传感，同时忽略发泡剂和漂浮物。 The LLC2 series printed circuit board is conformally coated to resist moisture and corrosion.

工作原理

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.
