SKF
Sensors for Use with Lubrication Systems
SKF sensors for lubrication systems are the active measurement elements — flow meters, pressure transducers, proximity sensors — that feed data to the controller or PLC. Flow meters measure the actual volume of oil or grease passing through a line, providing confirmation of delivery. Pressure transducers monitor system pressure, detecting blockages (high pressure) or leaks/empty reservoirs (low pressure). Proximity or Hall-effect sensors track the movement of piston distributors to verify a progressive block has cycled. These sensors are designed to handle the viscous, high-pressure nature of lubricants and the industrial environments in which they operate. Accurate, reliable sensor data is the foundation of condition-based and automated lubrication, enabling the shift from reactive to predictive maintenance.

Why Coriolis Flow Measurement Is the Gold Standard for Oil Circulation
A Coriolis meter measures true mass flow and density, independent of oil viscosity changes with temperature. In a turbine oil system, this means the measured flow is accurate whether the oil is cold at start‑up or at 60°C running temperature, providing reliable protection data.
Trending System Pressure to Predict Distributor Wear
A gradual increase in pump pressure over months, as logged by the pressure transducer, indicates that metering distributors may be gumming up or wearing. This trend allows the maintenance team to plan a cleaning or replacement during the next outage, before a blockage occurs.
