SWI L180/L190 Series | Intermediate & Large-Size Buna-N Float Level Switches

Description

The intermediate-sized L180 and large-sized L190 are equipped with a Buna-N float that provides optimum displacement and excellent stability in both oils and water. An optional stainless steel float is also available to accommodate aggressive environments. The two models are rated for system pressures up to 150 PSIG and temperatures up to 180º F. The L190, however, is best suited for highly viscous fluids.

Principles of Operation

A hermetically-sealed reed switch is actuated by an internal magnet within the float. As the float rises and falls with the liquid level, the magnetic field passes the switch encapsulated within the stem and causes the contact to either open or close.
