Level Switch
Model L-5

Adjustable Heavy Duty Level Switch

SPECIFIC GRAVITY ADJUSTABLE
(Stainless Steel or Brass)

Featuring continuously adjustable float buoyancy control to allow use in fluids with specific gravity down to 0.6.

Continuous buoyancy control allows switch activation at oil/water interface.

May be used in hazardous areas when used with intrinsically safe relays.

Consult factory for other dual-component fluid interface systems.
