Add-on Zone 1/21


The Valve Sense mobile inspection system for leak detection in valves combines high-quality acoustic emission sensors with the 5G smartphone IS540.1 and the Senseven software. Intuitive operation, automatic leak detection, structured data management and a high-quality processor for fast data processing make it a unique maintenance tool in demanding industrial environments.


  • User-friendly application without expert knowledge
  • Leakage detection through algorithms and artificial intelligence
  • Software-guided inspection process
  • Automated data transfer in cloud-based back office
  • Cost savings through predictive maintenance
  • Avoidance of unplanned production downtimes
