Bühler CMS – Condition Monitoring System
The CMS Condition Monitoring System is designed for the continuous monitoring of oil condition in hydraulic and lubrication systems. Using various integrated sensors, key parameters such as temperature, conductivity, permittivity, relative humidity, and oil cleanliness class are permanently recorded. These measurements allow reliable assessment of oil aging as well as the remaining service life.
The system continuously monitors the oil condition and detects changes at an early stage—regardless of whether they develop slowly or occur suddenly. This permanent analysis ensures stable and reliable operation of hydraulic and lubrication circuits.
Special sensors are available for detecting different types of contamination. The BPM 100 particle monitor measures the quantity of solid particles in the oil and precisely indicates the degree of contamination. The BMD 100 metal detector additionally detects ferromagnetic and other metal particles, typically found in gearboxes or heavily loaded system areas. The BCM LS sensor complements this monitoring by measuring relative humidity, temperature, permittivity, conductivity, and tank fill level. Together, these sensors provide an accurate overview of the current oil condition, enabling reliable fluid assessment.
Depending on the application, different versions of the CMS system are available. The devices can be permanently mounted, used as portable equipment, or integrated as mobile solutions. This flexibility allows seamless integration into existing machinery, maintenance processes, or service operations.
The CMS Condition Monitoring System thus provides a clear and precise method for comprehensively monitoring the condition of hydraulic and lubrication oils and reliably detecting changes. It creates full transparency regarding the operating fluid and supports stable performance of the entire system.
