Overview
Wear and oil condition in the same sensor
Highly integrated device: ferrous and non-ferrous wear, viscosity, density, temperature, water activity and moisture, with optional dielectric constant and free water. Compact and rugged, ideal for wind turbine gearboxes and heavy equipment.
What it measures
Everything it integrates
Ferromagnetic particles
5 ranges, from 40 µm
Gearbox metal wear counted by electromagnetic induction.
Non-ferromagnetic particles
5 ranges, from 150 µm
Non-ferrous metals classified separately.
Viscosity
1–1000 cP (±5%)
The number 1 quantity in lubrication, at the same point.
Density
600–1250 kg/m³ (±3%)
Changes in oil composition and contamination.
Micro moisture
1–5000 ppm (±10%)
Dissolved water over a wide range, for severe duty.
Water activity
0–1 aw (±3%)
Relative saturation before free water forms.
How it works
Measurement principle
Faraday electromagnetic induction for wear + fluid sensors for viscosity, density, moisture and temperature.
1
Faraday inductionResonating coil groups detect the metal wear particles.
2
Piezoelectric vibrationThe vibration mode measures viscosity and density.
3
Capacitors + PT100Polyimide film and a PT100 sensor measure water activity, micro moisture and temperature.
4
OutputRS485 MODBUS RTU; dielectric constant and free water optional.

Common questions
FAQ
How does it differ from the 6-in-1 Sensor?
The 6-in-1 covers the oil's physical-chemical quantities. This sensor adds ferromagnetic and non-ferromagnetic metal wear, in a single rugged body built for wind turbine gearboxes and heavy industry.
What comes as optional?
Dielectric constant and free water.
How is it installed?
SAE flange, stainless steel and aluminium body, IP65 protection.
Is there a mounting recommendation?
Yes. To reduce interference from air bubbles in the circuit, mount the sensor vertically, with the oil inlet facing down and the outlet facing up. If horizontal mounting is required, the air outlet end should face down.
