Yes — online oil monitoring systems can be used in both engines and hydraulic systems, but the purpose, sensor types, and monitored parameters may differ slightly between the two.
In engines (diesel, gasoline, gas engines), online oil monitoring helps track:
Oil degradation / oxidation
Viscosity changes
Soot and fuel dilution
Water contamination
Wear metal particles
Additive depletion
These parameters help prevent engine failures, reduce downtime, and extend oil change intervals.
Typical applications:
Trucks, buses, generators, marine engines, mining machinery, construction equipment.
In hydraulic systems (industrial and mobile equipment), the focus is usually on:
Particle contamination (ISO cleanliness levels)
Water content
Air entrainment / foam
Viscosity stability
Wear debris trending
Hydraulic systems are extremely sensitive to particle contamination, so online particle counters and moisture sensors are essential.
Typical applications:
Injection molding machines, presses, excavators, wind turbines, industrial hydraulics, power units.
| Aspect | Engines | Hydraulic Systems |
|---|---|---|
| Main concern | Oil degradation & wear | Cleanliness & water |
| Common sensors | Dielectric, viscosity, ferrous wear, temperature | Particle counter, moisture sensor, ferrous debris |
| Oil type | High-temperature engine oils | Hydraulic fluid with anti-wear additives |
| Failure risk | Overheating, bearing wear | Valve sticking, pump failure, system inefficiency |
Online oil monitoring systems are fully suitable for both engines and hydraulic systems.
The monitoring needs differ, but the core idea is the same: real-time oil condition analysis to prevent failures, reduce costs, and extend equipment life.
