Condition monitoring for hydraulic oil and lube oil

The condition monitoring of hydraulic oil, lube oil, gear oil and other fluids via online monitoring and/or on-site is an important part of a professional oil care and oil analyses program. Regular oil analysis functions for documentation of oil condition and trend curves as well as for the check whether the oil cleanliness required by the manufacturers of the sensitive components is achieved.

The continuous monitoring of contaminants (particles, water), wear debris, oxidation rate, total acid number (TAN) / total base number (TBN) and viscosity etc.:

  • send us information about the oil condition and machine condition
  • enable the detection of wear and leakages at the earliest and condition-based maintenance
  • enable control whether an oil change or an additional fine filtration in the off-line circuit is necessary
  • enable control of efficiency and performance of the in-line and off-line filter

Only with an oil cleanliness level that meets the application-specific requirements, it is possible to achieve the maximum regarding performance, availability and lifetime of machines and engines and to minimize maintenance costs simultaneously.

The DIGI oil analysis sets in transportable cases are ideal for quick condition monitoring and oil analysis on-site.

The CJC® Cyber-Physical-System, the CJC® Oil Contamination Monitor and the CJC® Condition Monitoring Unit are ideal for continuous condition monitoring and enable due to individual implementable oil sensors the optimum adjustment to machine- and application-specific requirements.
