Johnson Pump Ultima Switch Auto Control with Mirus Technology - Water Level Sensor for Submersible Pumps

Ultima Switch

New digital technology uses the Mirus field effect detector cells producing micro-electrical fields that detect disruptions caused by water and fluids. Detector cells are totally sealed, 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. A 3 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
  
  
  

The Johnson Pump Ultima Switch with Mirus technology is an advanced water level detection device designed for reliable operation in various applications. Utilizing new digital technology, it employs Mirus field effect detector cells that generate micro-electrical fields to accurately identify disruptions caused by water and fluids. These sealed, solid-state detector cells are completely isolated from water contact, eliminating corrosion risks and ensuring long-term durability even in challenging environments. The switch activates at a fluid level of approximately 2 inches and deactivates at about 3/4 inch, with a built-in 3-second delay to prevent false triggering during transient conditions. It is rated to handle all Johnson Pump submersible pumps up to 20 amps at both 12V and 24V systems, making it suitable for a wide range of marine, industrial, and commercial uses. The device features a unique 3-way switch that disables the piezo alarm while keeping the warning LED illuminated, providing flexible alert options for operators. Its environmentally sensitive design ensures safe and reliable performance across diverse settings, without the use of mercury or exposed sensors that could lead to corrosion. The Ultima Switch's robust construction and innovative technology make it an essential component for maintaining fluid levels efficiently and safely in your pumping system. For detailed installation and operation instructions, refer to the official Johnson Pump manual available online.
