The L500C is a remote chamber level switch that provides a machined, high-pressure, bottle housing for mounting outside the tank in applications where inside mounting is impractical. The vertically installed device features an all-brass or 316 stainless steel body with 316L stainless steel internal float assembly.

Rated for operating pressures up to 750 psig (51 bar) at 70°F and maximum operating temperatures to 300°F, the level switch has a solid metal housing that can contain over pressure to 1,500 psig. In addition to offering higher system pressures than similar type cast housings, it boasts a wider inside chamber that affords ample clearance between the float and the chamber wall to avoid particle entrapment and jamming.

The L500C can be equipped with 3/4 or 1 in. npt ports and an optional 1/2 in. npt conduit connector. With both SPST and SPDT elements available, it has magnetically coupled switch operation that can be reversed by inverting the float position.

Suitable for small or large tanks and cooling towers, the L500C measures about 6 in. in height and installs at the actuation level point. A compact aluminum bottle version is also available with 1/4 in. npt connections for smaller volume applications.
