Analysis sensor detecting air and gas bubbles


  • For hygienic and industrial applications
  • No matter what's the medium texture, from liquid to viscous as fruit concentrate or cooling agents (DK >1,5)
  • Extremely robust design for particularly harsh environments ​
  • Individually adjustable switching outputs with IO-Link (2) to configure switching range or two-stage alarm (early warning)
  • Optional, multicolor process visualization through 360° for different switching statuses

Baumer Bubble Sensor PAD20 wins International FoodTec Award

The unique PAD20 bubble sensor for air and gas bubble detection receives the next innovation award. After winning the Dairy Technology Award 2021, the analysis sensor has now also convinced the expert jury of the International FoodTec Award 2024 of the German Agricultural Society (DLG). 

The solution to a long-standing problem

The smart sensing principle of PAD20H/S will identify any air and gas bubbles in the process medium. Furthermore, the sensor also signals whether a closed system is free of them.

Clever and innovative functions:

  • Media-independent, from liquid to viscous for maximum flexibility
  • Individually configurable switching range with optional early warning upon exceeding the defined switching threshold
  • Convenient evaluation of measured and process values with two separately adjustable switching points (IO-Link)
  • Intuitive and fast commissioning by graphical parameterization software
  • Multicolor, particularly resilient process visualization through 360°
