6-in-1 Oil Condition Sensor
Overview

One sensor, the lubricant's whole health

MAXLUBE's reference multi-parameter platform for oil condition monitoring. In a single measurement point it gathers the main oil quantities, viscosity, density, dielectric constant (quality), water activity, moisture and temperature, reducing the number of installed sensors and delivering a complete, real-time view of lubricant health.

What it measures

6 parameters in a single measurement point

Viscosity

1–1000 cP (±5%)

The number 1 quantity in lubrication, measured continuously in the circuit itself.

Density

600–1250 kg/m³ (±5%)

Tracks changes in oil composition and contamination.

Dielectric constant

1–6

Quality index that reflects lubricant deterioration.

Water activity

0–1 aw

Detects relative saturation before free water forms.

Moisture

0–1000 ppm

Dissolved moisture content in parts per million.

Temperature

0–100 °C

Thermal reference for compensation and system diagnostics.

How it works

Measurement principle

Piezoelectric-resonance MEMS elements with an integrated high-precision signal sampling and processing unit and a built-in algorithm, simultaneously detecting temperature, viscosity, density, dielectric constant, water activity and moisture (no wear counting).
1
Immersion in oilThe MEMS element resonates in direct contact with the lubricant.
2
Signal samplingA high-precision integrated unit processes the element response.
3
Built-in algorithmConverts the response into 6 simultaneous oil quantities.
4
Digital outputValues published over RS485 MODBUS RTU to your system.

Common questions

FAQ

Does the 6-in-1 measure wear particles?
No. It covers 6 physical-chemical oil quantities (viscosity, density, dielectric constant, water activity, moisture and temperature). For real-time metal wear, see the Metal Wear Particle Sensor or the Wind Turbine Gearbox Oil Sensor.
How does the sensor talk to my system?
Through the RS485 output with MODBUS RTU protocol, an open standard supported by industrial PLCs and SCADA systems.
Does it replace laboratory analysis?
It complements it. The sensor delivers a continuous 24/7 trend on the equipment; the lab remains valuable for detailed periodic analyses. Full specifications in the official datasheet.
Which fluids does it monitor?
Lubricating, hydraulic and gear oil, plus diesel, gasoline, jet fuel, biodiesel, ethanol and other industrial fluids. Factory calibration uses 68# hydraulic oil, with custom calibration for other fluids.
