SPECIFIC GRAVITY COMPENSATING.
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.
