Johnson Pump Ultima Electronic Level Switch 12/24v

New digital technology uses the patented Mirus field effect detector cells producing micro-electrical fields that detect disruptions caused by water and fluids. Detector cells are totally sealed, never in contact with the water, will not corrode and are not affected by oil or foreign debris. Nomoving parts, totally sealed solid state electronics and field detectors, no mercury and no exposed sensors eliminate corrosion possibilities and makes the ULTIMA switch environmentally sensitive. ULTIMA activates at a 50mm (2”) fluid level and deactivates at a 20mm (¾) fluid level. An 8 sec. delay prevents false starts.
