Baumer Level Sensors are precision instruments developed by Baumer Group, a Swiss-based manufacturer known for sensors, encoders, and process instrumentation. These sensors are used to detect and monitor the level of liquids, pastes, powders, or granules in tanks, silos, or pipelines. 🏢 About Baumer Group Founded: 1952 Headquarters: Frauenfeld, Switzerland Core Products: Sensors, encoders, measuring instruments, vision systems Industries: Food & beverage, pharmaceuticals, packaging, automation, marine, and more 🔍 1. Types of Baumer Level Sensors Baumer offers a range of level sensing technologies, including: ✅ 1.1 Capacitive Level Sensors Detect level based on changes in capacitance caused by material presence. Ideal for: Liquids, solids, powders, or pastes Non-conductive and conductive media Examples: CleverLevel PL20 (universal point level detection) LBFS series (for hygienic and industrial use) Key Features: No calibration needed for media changes Immune to buildup, foam, and bubbles Can detect interfaces (liquid/liquid or liquid/foam) ✅ 1.2 Ultrasonic Level Sensors Use high-frequency sound waves to measure distance to the surface of a liquid or bulk solid. Suitable for: Open tanks, containers, or bins Harsh or dusty environments Key Features: Non-contact measurement Ideal for aggressive or sticky substances Long measuring ranges available ✅ 1.3 Hydrostatic Level Sensors Measure pressure at the bottom of a tank to determine the liquid height. Suitable for: Water, oil, or other fluids in tanks and wells Deep or pressurized tanks Features: High precision and stability Submersible options Temperature-compensated ✅ 1.4 Guided Wave Radar (GWR) Sensors (limited use in Baumer’s lineup) Use microwave pulses guided along a probe into the tank. Good for: High-pressure and high-temperature applications Differentiating between layers 📏 2.
