Keep Watch of
Rotating Machinery

Designed to assess and monitor an array of assets, the Sparrow sensor excels at detecting faults with remarkable anticipation, thanks to its high-frequency capabilities. Built with materials resistant to dust, water, and common solvents, it thrives in diverse environments, and its battery has a typical lifespan of 2 years, ensuring continuous, hassle-free operation. The Sparrow is the ideal vibration monitoring sensor for:

  • Non-critical assets
  • Stationary machines without gearboxes
  • Large-scale facilities with a high number of rotating assets
