From Traditional Diagnostics to Real-Time Insight: Discover VaRoM

Conventional valve monitoring methods in diesel and HFO engines rely heavily on manual inspections, compression tests, and audible diagnostics. These approaches are reactive and limited—often only detecting issues after serious damage has occurred.

In a typical setup, two technicians are required to inspect valve movement visually or through indirect indicators such as cylinder pressure loss. Unfortunately, these methods cannot provide real-time data, especially from inside the engine during operation. Valve seizure or breakage often leads to catastrophic failures, damaging pistons, cylinder heads, and turbochargers—resulting in lengthy downtime and high repair costs.

Introducing VaRoM: A Revolutionary Approach

VaRoM (Valve Rotation Monitoring) breaks the limits of traditional monitoring by providing continuous, wireless, and batteryless tracking of valve rotation and temperature while the engine is running.

  • Measures valve rotation speed, valve stroke (optional), and temperature in real-time.
  • Installs directly on the valve, even inside harsh engine environments.
  • Requires no wiring or batteries – powered entirely by vibration-based energy harvesting.
  • Transmits data via Bluetooth Low Energy (BLE), eliminating the need for cabling.
  • Integrates seamlessly with SCADA and HMI systems for full monitoring and visualization.

With VaRoM, operators gain 24/7 access to critical valve data and can act before a failure happens. Early detection allows for predictive and preventive maintenance, significantly reducing the risk of engine breakdowns.

The Future of Engine Monitoring Starts Here

VaRoM is more than a sensor—it's a smart, sustainable, and maintenance-free solution that empowers operators to make proactive decisions.

If you're ready to move beyond outdated diagnostics and embrace real-time visibility, VaRoM is the breakthrough you've been waiting for.
