Our OCM technologies


Oil condition sensor from Tan Delta monitors oil & provides results in real time.

FSH Core Technology

Full Spectrum Holistic (FSH™) core technology is a fusion of real time oil condition analysis and analytics working together to create a single sensor solution.

The electro-chemical properties of oil are analysed in real time, to an accuracy of 0.001%. This means users get a continuous stream of very high quality raw data, with analytics that provides deep insight on the real status of oil & equipment.


Advanced Fault Detection™

Advanced Fault Detection™ (AFD) alerts plant managers or operators at any sign of any possible issue that might cause equipment failure or damage.

Using this technology, plant managers can implement targeted, strategic interventions, reducing breakdowns and increasing equipment longevity.

Dynamic Maintenance Optimisation™

Dynamic Maintenance Optimisation™ (DMO) means plant operators / managers can easily optimise maintenance schedules to equipment need.

DMO helps identify optimal maintenance schedules for equipment safely & accurately, enabling efficient advanced planning, increased service intervals, reduced costs & less equipment down time.
