In today’s industrial landscape, pump protection is more critical than ever. Cavitation and dry run incidents can lead to significant downtime and costly repairs. These issues often stem from the presence of gas bubbles in fluid flows—a problem that traditional sensors struggle to detect reliably.

PAD20 addresses this challenge with its innovative sensor technology. Designed by sensor experts at Baumer, PAD20 offers a precise solution for detecting even microscopic air and gas bubbles in fluids. The sensor’s sophisticated algorithms enable it to identify any excess gas content quickly and accurately, triggering alarms or initiating pump shutdowns as needed.

How PAD20 Works

At its core, PAD20 utilizes dc-value based detection (where dc represents the dielectric constant) to measure deviations in fluid flow. This method is effective for fluids with a minimum conductivity of dc > 1.5. The system operates independently of the medium being monitored, making it highly versatile.

“The sensor measures dc deviation and this way provides maximum flexibility,” explains Julian Budde, Baumer’s Product Manager. Users can define two individual switching ranges to tailor the sensor’s response to their specific process requirements.

Applications Across Industries

PAD20 is suitable for a wide range of applications, from brewery technology to heating systems. Its reliability extends to viscous media such as oil and fluids like milk, ensuring consistent performance across different industries.

Key Benefits:

  • Early Detection: Identifies gas bubbles before they cause damage.
  • Versatility: Works in various industrial and hygienic settings.
  • Efficiency: Reduces maintenance effort and downtime.
  • Digital Integration: Features an IO-Link interface for condition monitoring and data collection.

Conclusion

PAD20 represents a significant advancement in sensor technology, offering precise detection of gas bubbles to protect pumps from cavitation and dry run. Its ability to adapt to various process requirements makes it an invaluable tool across multiple industries.
