Baumer Ultrasonic Level Sensors are non‑contact level measurement devices that use ultrasonic waves to determine the level of liquids or solids by measuring the time it takes for sound pulses to reflect back from the surface. This technology makes them suitable for a wide range of media and environments because they do not require contact with the medium and are resistant to contamination, dust, and soiling. They work effectively across small containers up to large tanks with ranges up to approximately 6 m.
The ultrasonic sensors in this category include miniature designs for narrow openings, robust versions with short blind zones and IO‑Link support, medium‑distance solutions with analog or switching outputs, and long‑range variants for level and limit detection over several meters. They combine high process safety with flexibility in parameterization and analog or digital signaling options to integrate seamlessly into industrial automation systems.
