Float level sensors are electromechanical devices that measure liquid levels using buoyancy principles. They consist of a floating element mechanically linked to a sensing component, providing continuous or point-level detection. These sensors play a critical role in industrial automation, ensuring process efficiency, safety, and resource optimization across sectors like water treatment, energy, and manufacturing.
| Type | Functional Characteristics | Application Examples |
|---|---|---|
| Magnetic Float Switches | Hermetically sealed contacts activated by float movement | Water tanks, fuel storage |
| Mechanical Lever Arm | Physical linkage translating float motion to potentiometer | Industrial boilers, hydraulic systems |
| Guided Tube Float | Float moves along a vertical tube, triggering reed switches | Chemical processing, corrosive environments |
| Optical Float Sensors | Combines float mechanism with infrared detection | Medical equipment, cleanrooms |
A typical float level sensor comprises: - Float Element: Hollow cylinder made of stainless steel, plastic, or titanium - Guide Mechanism: Rigid rod or cable for vertical movement guidance - Sensing Assembly: Reed switches, potentiometers, or Hall-effect sensors - Enclosure: IP65-rated housing with process connections (NPT, flanges) - Electrical Interface: Terminal block or industrial connectors (M12, etc.) The design ensures reliable operation in media with specific gravity 0.5 and temperatures up to 200 C.
