Flotect Level Switches
Series L8 FLOTECT® Liquid Level Switch
Low Cost — Leak Proof Body — Excellent Chemical Resistance
Series L8
The Flotect Series L8 Liquid Level Switch features a leak-proof body and float constructed from tough, durable polyphenylene sulfide which has excellent chemical resistance. Because the liquid level snap switch is magnetically actuated, there is no direct mechanical linkage to leak or fail, assuring longer life and decreased maintenance costs.
This inexpensive unit is ideal for liquid level alarm, indication or control. Installation is quick and easy — simply install in a horizontal position with the index arrow pointing down.
The L8 is UL recognized as an industrial motor controller per UL standard 508, suitable for mounting in a protected environment. This lightweight switch can be used in numerous chemical processes, industrial systems and similar applications where process conditions are compatible with polyphenylene sulfide, ceramic 8 and 316 stainless steel.
