Eaton Helicopter Debris Monitors and Oil Debris Monitoring Systems

Why Debris Monitoring Matters

In aerospace applications, early detection of wear and metallic particles can mean the difference between routine maintenance and total system failure. Debris monitoring systems continuously inspect lubricating oil for particles caused by internal wear. Benefits of helicopter debris monitors include:

• Provides early wear detection to prevent engine or gearbox failure.
• Allows maintenance to plan and intervene before costly downtime.
• Supports safety and regulatory compliance.
• Can reduce overhaul costs by tracking particle trends.

Debris monitors help protect critical elements and maintain operation standards.

Types of Eaton Debris Monitoring Systems

At Herber Aircraft, we supply the Electromesh® Lube System Debris Monitor from Eaton’s Glenolden helicopter product line, which is configured to capture and indicate the presence of conductive, non-ferrous debris particles such as aluminum, magnesium, phosphor bronze, and Babbitt material. The heart of the system is a uniquely woven screen that traps the debris and closes an electrical circuit to indicate its presence.
We also supply the Eaton Electronic Oil Debris Monitoring System (DMS), which consists of an inductive debris sensor/collector, a highly efficient vortex debris separator, and an electronic module. This device sends debris particle-count signals to the full-authority digital engine control (FADEC). The heart of the system is a magnetic, inductive particle sensor. It captures and retains ferromagnetic debris particles and provides an output signal for each capture.

Applications of Helicopter Debris Monitors

Eaton debris monitoring systems are used across many helicopter platforms and systems, including Sikorsky, Bell, and Airbus. Specific installation applications can include:

• Main and tail rotor gearboxes
• Engine lubrication systems
• Transmission assemblies
• Accessory drive systems

As a distributor of Eaton debris monitors, we support accurate debris monitoring applications with high-quality, reliable devices.

How to Choose the Right Debris Monitor

When it comes to selecting a debris monitor, there are several factors to consider:

• Aircraft system type: Identify where the monitor will be installed, such as the engine, gearbox, transmission, or accessory drive.
• Wear particle type: Determine if wear particles are ferrous or non-ferrous. Ferrous particles typically require chip detectors, while conductive or non-ferrous particles may require the Electromesh® system.
• Operational priorities: Decide if your goal is early warning or full debris counting.
