Johnson Pump Ultima Switch Auto Control with Mirus Technology – Fluid Level Sensor for 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 a highly reliable and maintenance-free fluid level sensor designed for various pumping applications. Utilizing advanced digital technology, it employs Mirus field effect detector cells that generate micro-electrical fields to detect water or fluid disruptions without direct contact. This sealed, solid-state design ensures the switch will not corrode or be affected by oil or debris, making it suitable for harsh environments. The Ultima Switch activates at a 2-inch (50 mm) fluid level and deactivates at a 3/4-inch (20 mm) level, providing precise control for pump operation. A built-in 3-second delay prevents false triggers, ensuring stable performance during fluctuating conditions. Rated to handle all Johnson Pump submersible pumps up to 20 amps at 12 or 24 volts, this switch offers versatility across many marine, industrial, and agricultural applications. Its environmental sensitivity and robust construction make it an ideal choice for demanding fluid management tasks. The device features a unique 3-way switch that disables the piezo alarm while keeping the warning LED active, giving users flexible notification options. With no exposed sensors or moving parts, the Johnson Pump Ultima Switch ensures long-lasting, corrosion-resistant operation, reducing maintenance needs and increasing reliability over time. This product comes with an owner’s manual for installation and maintenance guidance, ensuring proper setup and optimal performance for your specific needs.
