  • What are the characteristics of particle contamination that can lead to degraded lubricant health and negatively impacted machinery?

    The characteristics include particle size, particle count, surface area, particle shape/ angularity, hardness, density, composition, polarity, magnetic susceptibility and conductivity.

    What are the consequences of particle contamination to machinery?

    Particle contamination restricts oil flow and mobility of a machine’s moving parts. This could leave a business in a precarious position when it comes to managing expensive repairs and production losses.

    To what classifications are the cleanliness results shown?

    The cleanliness results are shown according to ISO/SAE or ISO/NAS classifications.

    What are suitable applications for HYDAC’s contamination sensor CS 1000?

    HYDAC’s contamination sensor CS 1000 can be used in several different applications, including industrial hydraulic and lubrication systems and mobile hydraulics.

    What are the features of HYDAC’s contamination sensor CS 1000?

    Features of this sensor include the ability to identify critical machine monitoring in good time and switch between ISO 4406:1999/SAE AS 4059 and ISO 4406:1987/NAS 1638 (only CS 13xx...). Continuous monitoring of oil conditions also takes place and condition-based maintenance planning.
