HYDAC Virtual Fluid Lab VFL sensor with IO-Link interface

Click2Contact

The Virtual Fluid Lab VFL sensor with IO-Link interface has been developed to provide a solution that can determine the remaining service life of a hydraulic filter element on the basis of pressure difference measurements. The sensor does this by using an internal algorithm to convert the filter’s pressure signal and the temperature of the fluid (which is read via IO-Link) into the current remaining service life of the filter element. This means that a signal is available that can be used for optimum planning of service work.

After the start-up phase, during which a constant remaining service life is output (9999 h), the actual calculated remaining service life will be provided to the IO-Link master. This value decreases linearly as the operating hours of the filter element increase.

The fluid compatibility includes hydraulic oils, lubrication oils and HFD as well as all environment-friendly fluids.

The Virtual Fluid Lab is used in plants where continuous, intelligent monitoring of the remaining service life is needed to enable organised service and to make full use of the filter element’s service life. The sensor is typically installed in a filter housing.
