🔍 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
