Liquid

| Prex
float switch, innovative hydraulic regulator, has been designed to
manage the level of liquids in critical contexts and industrial applications,
where the hydraulic pressure makes common float switches unreliable.
The working out of a new design, as well as the case moulding process
and the new sealing system, have been focused on achieving a superior
quality in terms of seal and mechanical resistance, both guaranteed
up to a depth of 50 m. The high buoyancy allows the immediate activation
of the high power microswitch: 20(8) A 250V, which permits the direct
control of 1HP pumps at 117 V and of 2HP at 230 V. Made from totally
atoxic reusable material, it doesn't contain mercury and is therefore
suitable for alimentary uses. Available with various types of cables,
PVC, H07, A07 and oil resistant, with three or four wire cables, Prex
comes in different versions: 250 V / 400 V microswitch, with golden
contact microswitch for low current absorption (max 0.1A) and with
piggy-back plug. |
