Revolution in Fluid Film Bearing Monitoring

Dries Van Loon, Application Engineer, PRUFTECHNIK


For the last 40 to 50 years, the industry standard to monitor bearing wear or machine problems on the most process critical and expensive equipment in each plant, has been the proximity probe.

A new revolutionary Insight Force Detection Sensor creates a cost effective and easy to install alternative. It provides the necessary data for condition monitoring and advanced analysis of all types of fluid film bearings.

In this presentation the measurement principal is explained, as well as case studies of real machine problems which were detected and identified using this new technology in combination with handheld and continuous monitoring solutions. Different applications are shown from Diesel Engines to Turbines and High Speed Compressors.

A must attend for all rotating equipment specialist and maintenance managers, eager to learn about this new (condition monitoring) life changing technology.


  1. Basic theory behind fluid film bearings and the current monitoring techniques
  2. Principle behind the new technology of the Force Detection Sensor
  3. Data examples, comparing different measurement technologies


After graduating as an electro mechanical engineer, specializing in maintenance, I worked for apredictive maintenance company actively using all existing predictive maintenance technologies throughout various different industries. After a few years I started working for PRUFTECNIK Benelux as an application engineer involving high-end troubleshooting using on and offline vibration measurements. As well as, the responsibility for all online condition monitoring projects, from initial design through installation and remote monitoring. Beginning 2014 I moved to the US office of PRUFTECHNIK where we are setting up a condition monitoring department to serve the US market on all CM related topics, including proactive maintenance, remote (temporary) monitoring, trouble shooting and torque measurements.

In 2017 I had the opportunity to participate in the ISO CAT 4 Vibration class and passed the exam,
becoming one of the youngest CAT 4 analyst at that time.
