In order to conserve resources and reduce operating costs, the service life of the oils in hydraulic systems and lubrication systems should be maximized.

In addition to system-compatible filtration with the aim of stabilizing the cleanliness class, this includes the permanent monitoring of various parameters using sensors such as the CM series from Bühler Technologies in Ratingen. These sensors keep an eye on the temperature, conductivity and permittivity of the oil. The aging of the oil and thus the remaining service life can be derived from these values. Why this effort?
Especially in lubrication technology, the oil has the status of a construction element and must have certain properties over its useful life in order to ensure the safe operation of the entire system. The desired properties are created by adding additives to a base oil. The additives will change as a result of the tribological loads in the course of operation and external loads such as moisture or air pollution, the oil ‘wears out’. In order for the above-mentioned sensors to be able to fulfill their task in a targeted manner, they become ‘familiar’ with the values of the fresh oil in a training phase, so to speak. The onboard algorithms then use the recorded values to calculate the probable service life of the oil and set appropriate limit values. If the correlation of the parameters to each other changes during operation, this affects the remaining service life and the CM sensor resets the limit values.
The course of the measured values of all parameters can be called up at any time via the ‘Data Viewer’ software included in the scope of delivery and, for example, evaluated in the form of course curves. If the end of the service life is imminent, the limit values can be overwritten and timed to the next planned downtime for maintenance.
