Parker's new FCS fluid condition sensor monitors the critical oil parameters of permittivity (dielectricity), water content, temperature, density, pressure and conductivity. According to the manufacturer, it is the only sensor of its type that can measure conductivity in nanosiemens per meter. The FCS sensor determines when the oil needs to be treated due to deterioration of the oil chemistry (oil condition) or contamination by liquids such as water or tramp oil. As part of a proactive maintenance program, the FCS sensor is designed to help reduce the total cost of ownership of machines as well as minimize downtime and the number of inspection checks and laboratory tests. The Parker FCS sensor is suitable for all mineral oil-based hydraulic fluids and lubricating oils.
