For use as a fill-level switch in wastewater pumping systems, industrial water tanks, rain water collection systems etc. To control any low and high level for liquids in all industries.
SPECIFIC FEATURES
The floats are moulded in polyethylene. The body is welded therefore perfectly tight. A micro-switch is used in conjunction with a balancing mass. It has a high switching power. The switch operates when the float pass across the horizontal axis. The standard cable is highly flexible (PVC with additives) accepts neutral, alkaline or lightly acid media. The oil version cable is of special PVC. The acid version cable (HCl 33%, HNO3, etc.) is polyethylene coated.
SS2 / W: cigar shaped, convenient for all clear fluids without sludge, (specific weight ≥ 1 kg/L).
SS2 / KW: the pear-shaped float switch is convenient for viscous media and wastewater pumping systems with residual paper content, presence of sludge, etc. (specific weight ≥ 1 kg/L).
SS2 / WH: oil version, mainly for liquids with a specific weight ≥ 0.9 kg/L
TECHNICAL FEATURES
Specific weight: ≥ 0.9 kg/L (SS2 / WH); ≥ 1 kg/L (SS2 / W and SS2 / KW) SwitchPotential-free micro-switch, changeover contact
Switching limits: 4 to 250 V AC / 4 to 30 V DC Caution: legal disposition When U> 50 V, the tank (fluid) has to be connected to earth otherwise the electrical loop has to be powered with a low potential current.
Switching power: 1 mA to 3 A / DC or AC Maximum temperature: 0...+60°C Maximum pressure: 0.5 bar (depth immersion < 5 m) Float: PE (polyethylene)
