The YFM8 Wear Debris Sensor is an online sensor that tests the quantity, size, and property of wear debris particles in oil. Most mechanical failures are caused by mechanical wear, and the debris particles generated by wear can truly reflect the wear condition of the equipment. The YFM8 adopts the advanced three‑coil electromagnetic induction principle, integrated with a high‑precision signal sampling and processing unit, and combined with advanced algorithms to achieve real‑time detection of both ferromagnetic and non‑ferromagnetic abrasive particles in the oil circuit.
Key Capabilities
- Ferromagnetic wear particles: >40 μm (5 channels)
- Non‑ferromagnetic wear particles: >150 μm (5 channels)
- Detection rate ≥85% across full range
- Particle detection rate: ≤100 particles/sec
- Total particle counting (Fe + Non‑Fe)

Description
Lubricating oil debris reflects the health of the equipment and is an important basis for diagnosing equipment failures and predicting equipment failures. The YFM8 oil wear debris sensor adopts the advanced three‑coil electromagnetic induction principle, integrated with a high‑precision signal sampling and processing unit, and combined with advanced algorithms to achieve real‑time detection of ferromagnetic abrasive particles and non‑ferromagnetic abrasive particles in the oil circuit.
By continuously monitoring wear debris in real time, you can predict mechanical failures before they occur, schedule maintenance proactively, and avoid catastrophic equipment damage and unplanned downtime.

Three-Coil Electromagnetic Induction
The YFM8 uses three electromagnetic coils to detect particles as they pass through the sensor bore. Ferromagnetic particles (iron, steel) and non-ferromagnetic particles (copper, aluminum) are distinguished by their different electromagnetic signatures, allowing accurate classification and counting.

Why Monitor Wear Debris?
Wear debris is the earliest indicator of mechanical failure. By detecting particles in real time, you can identify abnormal wear patterns before catastrophic damage occurs — enabling predictive maintenance and extending equipment life.
