Description

Control relay for emptying well or hole, with protection of submersible electric pumps against lack of water, indicated by led “Pump in Service” and “Thermal Shooting”.Adjustable sensitivity, according to the liquid conductivity (selected in the front button) 4 – 30 KΩ

Applications

• Level control in conductive liquids through three probes (minimum, maximum and mass), with maximum level protection
• Sensitivity adjustment 4 – 30 KΩ (depending on the conductivity of the immersion liquid)
• Protection of electric pumps from lack of water
• “Pump in Service” and “Thermal Shooting” indication
