Smart Sensors for Compressed Air Leaks: Fast Payback

Compressed air is one of the most expensive forms of energy in manufacturing — often accounting for 10–15% of total electricity. Smart sensors can detect leaks in real time, enabling fast repairs and measurable savings.

Why Air Leaks Matter

• A single 3 mm hole at 6 bar can waste over 10,000 kWh per year.
• Most plants lose 20–30% of compressed air through undetected leaks.

Smart Sensor Technologies

• Ultrasonic microphones detect high-frequency leak sounds.
• Flow and pressure sensors monitor abnormal drops in distribution lines.
• AI-based anomaly detection identifies leaks automatically using pattern recognition.

Integration with Automation

Connect sensors to PLCs or SCADA via IO-Link or Modbus. Alerts can trigger work orders in the CMMS, or even isolate sections automatically for maintenance.

Case Example: Automotive Plant

By installing 50 ultrasonic sensors, a Tier-1 supplier cut compressed air losses by 22%, achieving ROI in under six months.
