HLLSW Hansen Refrigerant Float Switch

These Hansen refrigerant liquid level float switches (HLL Series) are used to electrically indicate or control a liquid level by opening or closing a SPDT switch. Their simple, reliable design provides long life performance for almost any application. These refrigerant liquid level float switches are typically installed on a vessel’s liquid level column. They can control liquid level by controlling a liquid fill solenoid valve. Often, they are used to provide high level cutout or alarm. In addition, they can be used to turn off a recirculating liquid pump if a low level occurs. Other applications include control of liquid level via a liquid exit solenoid valve, level indication via a pilot light, and transfer drum operation.

This switch assembly is sealed in a clear housing to allow visual confirmation of switch action but protection from tampering. In addition, the switch is surrounded by an inert gas that provides an environment which inhibits corrosion.
