Level sensors are electronic devices that detect and measure the level of liquids, powders, and granular materials. They can be used in various industries for continuous level measurement, inventory control, and process automation.
Level sensors work based on various principles such as ultrasonic, capacitive, resistive, optical, and magnetic. Ultrasonic level sensors use sound waves to measure the distance from the sensor to the liquid surface, while capacitive level sensors measure the dielectric constant of the liquid to determine the level.
Resistive level sensors work by measuring the change in resistance when the sensor comes in contact with the liquid, while optical level sensors measure the level using light beams. Magnetic level sensors use the magnetic field to measure the level of liquids, and they are ideal for detecting the level of non-conductive liquids.
Level sensors are used in a wide range of applications such as wastewater treatment, oil and gas production, food and beverage, pharmaceuticals, and chemical processing. They are available in different sizes, shapes, and materials to suit the specific requirements of different applications.
