Parker Kittiwake Fluid Condition Sensor

On-line /Fluid/oil/fuel quality measuring instrument

Low quality, incorrect fuel or oil lubrication combined with infrequent maintenance is a cause of machinery damage, leading to expensive repairs. The Parker Kittiwake Fluid Condition Sensor (FCS) provides constant, real-time monitoring of critical oil parameters - permittivity (dielectric), conductivity, temperature, moisture content and pressure.

Our most technically accomplished multiparameter sensor

The Fluid condition sensor can measure any ,combination of the five parameters - oil quality (permittivity, ,conductivity) moisture, temperature and pressure - as required by the host machinery. The sensor is suitable for all hydrocarbon mineral-based hydraulic fluids and lubricating oils.

On diesel engines, the FCS may be used to monitor the common problems of fuel contamination, degradation of the oil and ingress of water from the cooling system.
