Each hydraulic oil is subject to thermal influences and changes. Foreign particles speed up aging and deterioration. So, there are several advantages to analyzing your operating medium on a regular basis: For instance, impurities can be detected early on and lubrication-related consequential damages prevented. This also delivers important indications of potential problems in your hydraulic system and the best possible time for oil changes.
Particle measurement in line with oil purity class ISO 4406 and NAS 1638 in running machinery.
Extensive analysis set for clean sampling, including lab report.
Standard analysis set for clean sampling, including lab report.
The required oil purity grade of your machinery depends, among other things on the specifications of the component manufacturer, the system operating pressure, the frequency of alternating pressure loads and your requirements with regard to machine availability.
The respective ISO 4406 purity class is generally derived from the particle content. The particle count is done either microscopically or automatically using a particle monitor built into the unit. The number of solid particles in 100 ml of the hydraulic oil being tested provide the ISO codes which correspond to the various different oil purity classes. As a general rule, a doubling of solid particles equates to an increase in the ISO class by one.
