1.2.1 Capteurs de type flottant
Principe : Un flotteur flottant se déplace avec la surface du liquide, transformant le déplacement vertical en un signal électrique ou mécanique.
? Advantages: Simple design, cost-effective, easy maintenance.<\/span>
? Limitations: Mechanical wear, lower precision in turbulent environments. <\/span><\/p>\n1.2.2 Capacitive Sensors \n ? Principle: A probe forms one plate of a capacitor; changes in dielectric constant of the surrounding medium alter capacitance, converted into level readings. \n ? Advantages: No moving parts, high reliability, suitable for viscous or corrosive fluids. \n ? Limitations: Sensitive to foam or dielectric variations, higher cost than float types. \n\n1.2.3 Ultrasonic Sensors \n ? Principle: Ultrasonic pulses emitted at the fluid surface reflect back; time-of-flight measurement indicates distance to liquid. \n ? Advantages: Non-contact measurement, minimal intrusion, applicable for dirty or contaminated fluids. \n ? Limitations: Affected by vapor, foam, and heavy condensation; higher initial investment. \n\n1.2.4 Pressure-Based Sensors \n ? Principle: A diaphragm or sensor at the tank bottom measures hydrostatic pressure; converts pressure to fluid height. \n ? Advantages: Good for deep tanks, high accuracy, compatible with high temperatures. \n ? Limitations: Requires installation at tank bottom, potential clogging in dirty fluids. \n\n1.2.5 Magnetostrictive Sensors \n ? Principle: A magnetic float travels along a waveguide; an electrical pulse interacts with magnetostrictive material to produce precise level readings. \n ? Advantages: High resolution, robust for harsh conditions, digital outputs. \n ? Limitations: Complexity and cost, requires precision installation. \n<\/code><\/pre>\n
