Gas Water Heater Spare Parts Magnetic Float Switch (Zero Pressure)
The magnetic reed float switch (zero pressure) is a reliable sensor specially designed for water level detection in gas water heater tanks. Using magnetic coupling with a non-contact detection method, the float moves up and down with the water level, and the magnetic field activates the internal reed switch to open or close the circuit. This ensures high sensitivity, leak-free operation, and long service life. It is suitable for household and commercial gas water heaters, including instant and storage types, especially for low-pressure or zero-pressure side detection.
Key Features
- Durable Copper Material - Ensures long-lasting performance and corrosion resistance.
- Accurate Flow Detection - Provides reliable water flow sensing for stable operation.
- Magnetic Sensor Design - Delivers quick response and consistent control.
- Wide Application - Suitable for most gas water heater models.
- Easy Installation - Compact structure allows simple replacement and maintenance.
