Submersible level sensors are specialized devices designed to measure liquid levels in tanks, wells, and other submerged environments. These sensors are widely used in industrial automation, water treatment, and oil & gas applications. Key features include waterproof construction, high accuracy, and resistance to corrosive substances. Common types include hydrostatic, ultrasonic, and capacitive sensors. Example products in this category may include submersible pressure transducers, float switches, and multi-parameter level probes. These sensors often feature robust materials like stainless steel or titanium housings, with output options such as 4-20mA, Modbus, or HART protocols for seamless integration with control systems.
