FDX Series Magnetic Float Level Switch

Introduction – FDX Series Magnetic Float Level Switch

The FDX Series Magnetic Float Level Switch is engineered for precise and reliable liquid level monitoring using the proven principles of buoyancy and magnetism. Designed with reed switches housed inside a stainless-steel or engineering-plastic stem, the system uses float balls containing sealed magnets that move with liquid level changes. This movement actuates the reed switches to create clean ON/OFF signals for accurate level indication.

Built as a top-mounted, multi-point level switch, the FDX Series provides an efficient solution where multiple measurement points are required from a single tank entry. Its rugged construction, long contact life, and wide material options make it suitable for demanding industrial environments. Dubai Sensor supports the FDX Series for applications across the UAE/MENA market, where durability and chemical resistance are crucial.

With customizable configuration options, the FDX Series adapts to a wide range of tanks, liquid properties, and operating conditions. It supports liquids with a minimum specific gravity of 0.45 S.G., offering versatility in industries such as chemical processing, shipbuilding, wastewater treatment, and food production.

Installation, Commissioning & Maintenance

The FDX Series Magnetic Float Level Switch is installed from the top of the tank, allowing multiple switching points through a single mounting entry. Floats are positioned based on required level points using graduated rings on the stem. During operation, the float magnets actuate reed switches without needing an external power source.

Maintenance is minimal due to fully isolated reed switches and rugged construction. Periodic checks ensure that float movement remains unobstructed and that the stem is free from buildup, particularly in high-viscosity or chemical environments.

Why Choose FDX Series Magnetic Float Level Switch

The FDX Series offers a robust and cost-effective solution for applications requiring multiple level detection points without complex wiring or multiple tank penetrations. Its flexible material options and high durability make it ideal for corrosive, high-pressure, and harsh industrial environments.

Supported by Dubai Sensor, the FDX Series delivers reliable performance across diverse industries, including marine, chemical, food processing, and wastewater treatment. Its long lifecycle, simple installation, and customization capability provide excellent value for industrial automation and process control systems.

Ordering Guide

1. Identify required number of switching points (single or multiple).
   
2. Select suitable stem and float materials (PVDF, PP, PVC, SUS304, SUS316) based on liquid properties.
   
3. Confirm minimum specific gravity of the liquid (≥0.45 S.G.).
   
4. Specify temperature and pressure conditions to determine standard or high-temperature/explosion-proof versions.
   
5. Choose mounting configuration and junction box requirements.
   
6. Provide tank dimensions and switching height positions for customization.

FAQ – FDX Series Magnetic Float Level Switch

Q1: How does the FDX Series Magnetic Float Level Switch detect liquid levels?
A1: It uses float balls containing sealed magnets that move with liquid level changes. When the magnet approaches the reed switch inside the stem, the contact opens or closes to generate an ON/OFF signal.

Q2: What is the minimum liquid density required for proper operation?
A2: The floats are designed for liquids with a minimum specific gravity of 0.45 S.G.

Q3: Can the FDX Series provide multiple level detection points?
A3: Yes. It supports multiple switch points using a single tank entry, with float positions customized to your application.

Q4: What materials are available for the stem and floats?
A4: Material options include PVDF, PP, PVC, SUS304, and SUS316, making the switch suitable for corrosive and industrial liquids.

Q5: Is the FDX Series suitable for high-temperature or high-pressure environments?
A5: Yes. Stainless-steel versions are suitable for high pressure and high temperature, and explosion-proof models are also available.

Q6: What is the expected contact life of the reed switches?
A6: Each reed switch has a life expectancy of up to 2 million operations.

Q7: Does the system require power for the float or magnetic actuation?
A7: No. The magnetic actuation requires no power. Only the output circuit requires standard wiring.

Q8: What protection rating does the switch housing provide?
A8: The minimum housing protection level is IP65.

Q9: In what industries can the FDX Series be used?
A9: It is suitable for shipbuilding, chemical processing, wastewater treatment, food and beverage, petrochemical, electronic manufacturing, dyeing/finishing, and other liquid-handling sectors.

Q10: Are the reed switches and wiring exposed to the liquid?
A10: No. The reed switch and lead wires are completely isolated from the liquid to ensure reliability.
