Oil Condition Monitoring for Mining Equipment

Extend service life, reduce unplanned repairs, and optimise maintenance across your mobile and fixed plant with real-time oil condition monitoring.

Oil Condition Monitoring for Mining Operations

Maximise uptime. Cut unplanned maintenance. Protect critical assets.

Why Oil Monitoring is Critical in Harsh Mining Environments

Mining equipment operates under intense load, extreme temperatures, and abrasive contamination. Engines, hydraulic systems, and gearboxes face fine dust, water ingress, and thermal stress—conditions that accelerate oil degradation and component wear.

While manual sampling remains a valuable tool, it captures only a moment in time. Tan Delta’s real-time oil condition monitoring provides continuous visibility, helping maintenance teams detect issues earlier, optimise service intervals, and prevent unexpected failures.

Continuous Monitoring for Fixed and Mobile Plants

  • Live Oil Monitoring

    Continuously tracks oil degradation, contamination, and wear.

  • Fits Any Equipment

    Use on haul trucks, excavators, crushers, screens, conveyors, pumps, and powerpacks.

  • Simple Installation

    Mounts using existing oil ports or sampling points—minimal disruption to operations.

  • TDN Output

    One numerical value summarises oil condition and trend. No lab required.

  • Easy Integration

    Connect to control systems, onboard displays, or remote monitoring tools.

  • Maintenance Alerts

    Detect early-stage failure and schedule intervention before it escalates.

Avoid Costly Failures Caused by Oil Degradation

  • Contamination Ingress

    Water, dust, or debris can enter hydraulic and lubrication systems, causing premature wear.

  • Thermal Degradation

    Extreme heat degrades oil, reducing lubrication and accelerating component fatigue.

  • Fuel and Coolant Dilution

    Unnoticed dilution compromises oil viscosity and load-bearing properties in engines.

  • Undetected Metal Wear

    Lack of visibility into fine metal particles causes critical failures in gearboxes and pumps.

  • Missed Failure Signals

    Intermittent or slow-developing issues may go unnoticed between manual samples.

  • Inefficient Servicing

    Fixed-hour service schedules often result in unnecessary oil changes or late interventions.

Proven Benefits Across Mining Fleets

PREVENT UNPLANNED DOWNTIME

Identify issues early and take action before they cause costly production stoppages.

OPTIMISE MAINTENANCE TIMING

Extend service intervals based on oil condition, without increasing risk to reliability.

CUT OPERATING COSTS

Lower oil, filter, and parts use while reducing labour and emergency repair expenses.

TRACK EQUIPMENT HEALTH

Continuously monitor critical assets like crushers, trucks, and hydraulic systems.

IMPROVE ENVIRONMENTAL OUTCOMES

Avoid unnecessary oil changes and reduce waste across your entire equipment fleet.

ENABLE PREDICTIVE MAINTENANCE

Act on live data trends instead of relying on fixed schedules or visual inspections.

Used Across Mining and Mineral Processing Plants

Tan Delta sensors are installed on mobile and fixed plant across surface and underground mining operations—including loaders, crushers, conveyors, vibrating screens, and powerpacks.

Maintenance teams use the data to optimise service intervals, reduce unplanned downtime, and identify issues early to avoid major failures. It’s a proven tool for improving asset performance and reducing waste.

Reliable Oil Monitoring for Harsh Mining Conditions

Tan Delta’s oil condition monitoring system is built for the demands of mining. It delivers real-time visibility into oil condition across engines, gearboxes, and hydraulic systems—helping reduce cost per tonne and maintain uptime in tough environments.

Oil Sensors

Real-time oil condition analysis for fixed installations in standard and hazardous environments.

Kits

Pre-configured kits with sensors, displays, and cabling — engineered for quick install into engines, gearboxes, hydraulics, and rotating equipment.

Accessories and System Interfaces

Displays, gateways, and manifolds for integration, readout, and remote monitoring in any environment.

Tan Delta enabled us to prevent a catastrophic failure which would have cost us hundreds of thousands of dollars.

The data we are getting is incredible. We can push our gear much harder with complete confidence.

Detecting degradation early has allowed us to prevent damage, and ensure equipment is always good to go.

Optimising our mobile plant maintenance across site allowed us to minimise downtime and increase productivity.

We have grown to trust Tan Delta’s solutions to tell us what’s really happening inside our equipment.

We were initially skeptical about whether we’d realise the cost savings, but not anymore.

Frequently Asked Questions

Yes. Tan Delta sensors are used across mobile equipment (such as haul trucks, loaders, and drills) and fixed plant (including crushers, pumps, and hydraulic systems). The sensor mounts into existing oil inspection points with minimal disruption.

The system supports all standard lubricating oils, including engine oils, hydraulic oils, gear oils, and compressor oils—mineral, synthetic, or biodegradable. No oil-specific sensor calibration is required.

Yes. For hazardous environments, the OQSx-G2 HAZ sensor is ATEX Zone II certified and suitable for applications where explosive gases or dust may be present.

Installation requires a flow-through point, typically using an existing oil inspection or sampling port. The sensor must be installed in a pressurised oil path with steady flow and temperature for accurate readings. No system redesign is needed.

The sensor continuously monitors a combination of dielectric and conductivity properties to detect oil degradation and contamination. This includes changes caused by oxidation, water ingress, fuel dilution, wear metals, and chemical additives.

TDN (Tan Delta Number) is a single real-time value that represents overall oil condition. It is calculated from the sensor’s raw data and allows users to track oil health and rate of change over time. TDN enables data-driven decisions on when to service or replace oil.

Data can be viewed via Tan Delta’s dedicated display units, transmitted to existing displays and control systems (SCADA, PLC), or accessed remotely via modem and the Tan Delta Online platform. Local and cloud-based options are available.

The system provides continuous real-time oil condition data that can reduce or eliminate the need for frequent manual sampling, depending on site requirements.
