Johnson Pump

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, and are never in contact with the water, will not corrode and are not affected by oil or foreign debris.

ULTIMA activates at a 50 mm (2") fluid level and deactivates at a 20 mm (3/4") fluid level. An eight second delay prevents false starts. ULTIMA switch is rated to handle all Johnson Pump submersible pumps pumps up to 20 amps at 12 or 24 volts.

Features

  • No moving parts
  • Totally sealed solid state electronics and field detectors
  • No mercury
  • No exposed sensors eliminate corrosion possibilities
  • Unique 3-way switch disables piezo alarm while keeping warning LED lit
  • Environmentally sensitive

Field effect dector cells Mirus dector cells are composed of an active device and an electrode surrounded by a second electrode.The applied circuit creates an electric field around the cell. When a dielectric material (such as bilge water) interrupts the field the active device responds by outputting a signal. In the case of the ULTIMA switch, this signal is used to automatically control your bilge pump.

Great product!

Great idea, no moving parts. I added a lenght of clear tubing and silicon seal to avoid any contact of the wires to water. So far works very well.
