Application

For electrician / automation specialist: Quick installation into existing tanks or silos. Easy connection to PLC, relay or signaling circuits. Low sensitivity to vibrations and environmental disturbances.
For engineer / project manager: Reliable solution for challenging media (dust, granular flow, foam). Suitable for Ex zones (explosion-hazardous environments). Low maintenance costs, long service life.
For food, chemical, pharmaceutical industries: Resistant to aggressive substances. Stable operation even when product properties change.
Pros

Works with both powders and liquids
Does not require calibration according to material
Resistant to dust, deposits and vibrations
Explosion-proof construction
Wide power supply and mounting options
Cons

Not suitable for extremely low-density bulk materials (< 0,23 g/cm³)
This is a level switch (ON/OFF), not a continuous level transmitter
