NBR FLOAT-MAGNETIC

Magnetic NBR Floats: Precision Fuel Level Sensing

As a critical component manufacturer, we produce magnetic NBR floats essential for accurate fuel level sensors in automotive and motorcycle fuel tanks. The operating principle is simple yet vital:

Buoyancy & Movement: The hollow NBR (Nitrile Rubber) float rides precisely on the fuel surface, moving vertically with level changes.
Magnetic Coupling: A permanent magnet sealed within the NBR core moves with the float.
Resistance Adjustment: This magnet actuates a nearby reed switch or hall-effect sensor, altering circuit resistance proportionally to fuel height.

Why NBR is Non-Negotiable:

Fuel Resistance: NBR withstands gasoline, ethanol blends, and diesel without swelling/degredation.
Seal Integrity: Prevents fuel ingress into the magnet cavity, ensuring consistent magnetic force.
Temperature & Durability: Operates reliably from -40°C to +120°C and resists tank sloshing/vibration.

Failure-proof NBR floats guarantee accurate gauging, prevent false readings, and eliminate sensor leaks – mission-critical for safety and operational confidence. Our rigorous material testing ensures uncompromising float durability. Trusted by leading OEMs worldwide.
