Design & Functionality
The switch operates through a sealed float containing a permanent magnet that moves along a vertical guide stem. Inside the stem, reed switches are positioned at specific points corresponding to desired liquid levels. As the liquid level rises or falls, the float travels along the stem and activates the reed switch contacts when the magnet approaches them.
This magnetic actuation creates an electrical signal that can trigger alarms, pumps, or automated process controls. Because the switching mechanism is magnetically actuated, the electrical components remain isolated from the liquid, increasing reliability and reducing maintenance requirements.
Total Crossed Beams
The internal sensing design enables multiple switching points within a single device. Each reed switch acts as an independent level detection point, allowing operators to monitor high, low, or intermediate liquid levels in one installation.
This configuration eliminates the need for installing several individual level switches, making it a cost-efficient solution for multi-level tank monitoring.
Beam Pitch Options
Switching positions can be customized to match the operational requirements of the tank or process vessel. Different pitch spacing between switch points allows users to configure precise level detection thresholds.
This flexibility ensures the device can be adapted for various tank sizes and process control systems.
Intrinsic Synchronism
The magnetic actuation system maintains stable switching behavior regardless of process variations. Since the reed switches respond directly to the magnetic field of the float, signal consistency is maintained even under vibration or fluid turbulence.
This ensures dependable performance in dynamic industrial processes.
Operational Advantages
The FDX Magnetic Float Level Switch offers a cost-effective and durable solution for industrial liquid level monitoring. Its robust design allows operation in high temperature, high pressure, and corrosive environments.
By combining simple installation, reliable switching performance, and multi-point monitoring capability, it becomes an ideal choice for industrial facilities seeking efficient tank level control and process automation.
