JUMO AutomationJUMO NESOS Float Level Switches and Point Measurement
Technical Principle: JUMO has been producing high-quality floats for over 40 years. Combined with proven measurement technology, this forms the core of JUMO NESOS point and level measurement systems. Floats with integrated magnetic switches activate one or more reed contacts via their magnetic field as the liquid level rises or falls. This enables switching without auxiliary power while ensuring contactless and wear-free operation. Extended Features: In addition to level switches, temperature switches with Pt100 or Pt1000 sensors can be installed for combined level and temperature monitoring. Customized solutions are available upon request. Key Benefits: Wear-free and maintenance-free; ideal for small measuring ranges (e.g., fuel tanks); independent of tank geometry and medium properties; simple setup and installation; quick inspection during maintenance. Applications: Point-level oil measurement in wind turbine gearboxes and hydraulic systems; fuel tank level monitoring; and combined level-temperature monitoring for various industrial equipment.
