ROCHESTER FPI SINGLE LEVEL FLOAT SWITCH CUSTOM INDUSTRIAL LEVEL SENSOR

The Rochester Sensors FPI Single Level Switch (part of the FPI Sensors line acquired by Rochester) is a high-reliability float-activated sensor designed for point level detection in diverse industrial liquids.

A durable, customizable single-point float switch utilizing magnetic reed technology for accurate high or low alarm liquid level monitoring.

ROCHESTER FPI SINGLE LEVEL FLOAT SWITCH CUSTOM INDUSTRIAL LEVEL SENSOR

Engineered for demanding industrial environments, the FPI Single Level Switch features a hermetically sealed magnetic reed switch inside a stem, actuated by a floating magnetic field. These sensors are highly configurable, offering various materials such as stainless steel, brass, and plastics to suit specific chemical compatibilities. They are designed to eliminate mechanical failure points, providing a long service life of up to 100 million cycles for critical applications like fuel management and wastewater treatment.

PRODUCT USES:

  • Tank Alarms: High-level overflow prevention and low-level dry-run protection for pumps.
  • Fuel Systems: Monitoring diesel and gasoline levels in generators, heavy construction equipment, and storage tanks.
  • Environmental: Oil/water separators and wastewater treatment equipment.
  • HVAC/R: Freon recovery and regulation in refrigeration units.
