One-float level switch for external side mounting, with one switching unit. For pressure up to 50 Bar max., temperatures between -10˚C and 135˚C for fluids with specific gravity of 0.85 kg/dm3 min. (1.0 kg/dm3 for the 56 model). Fixed differential, with SP.GR. 1 kg/dm3 , 30 mm. This means that 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 30 mm.

Set point accuracy ±5 mm.
