Float, Level Sensors

1. Overview

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.

2. Main Types and Functional Classification

TypeFunctional CharacteristicsApplication Examples
Magnetic Float SwitchesHermetically sealed contacts activated by float movementWater tanks, fuel storage
Mechanical Lever ArmPhysical linkage translating float motion to potentiometerIndustrial boilers, hydraulic systems
Guided Tube FloatFloat moves along a vertical tube, triggering reed switchesChemical processing, corrosive environments
Optical Float SensorsCombines float mechanism with infrared detectionMedical equipment, cleanrooms

3. Structure and Components

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.
