Buoyancy level switch for external side mounting with a

single switching unit. For pressure from 100 Bar to 400 Bar, for temperatures up to 135˚C max. and for fluid with a specific gravity of 0.55 kg/dm3 min.

Inspect-able body. Minimum differential of switch, at SP.GR.

1 kg/dm3, 75 mm. This means that if the change-over takes place by increased (or decreased) contact level, the following change-over will take place when the level falls (or rises) by 75 mm. 
Set point accuracy: ± 7 mm.
