  • Oil Condition monitoring solution
• System Overview:
  • WearSens® is a unique, new system for online oil condition monitoring. Early indication of oil changes leads to optimum loading and/or timely preventative maintenance. The result, huge savings in money, downtime and man hours.
  • Change in oil is one of the precursors of particle shearing and pitting in the bearing raceway. Early detection can warn of potential damage states, before damage occurs.
  • WearSens® works from day 1, prior to other technologies limits of detection. Tests have shown that the WearSens® can detect deterioration in oil while standard laboratory analysis still reports oil as good. Vibration and particle monitoring only detect after damage is done.
  • Conductivity, permittivity and temperature are measured with high precision. Both conductivity and permittivity are temperature dependent, but the temperature compensation for any pollutants is unknown. WearSens® features a self-adapting temperature compensation algorithm similar to a neural network.
  • Conductivity is measured in picosiemens per metre. This sensitive conductivity measurement indicates the formation of compounds from broken oil molecules, the presence of micro particles and the consumption of any additives. The temperature compensated values allow comparison at any time.
  • Relative permittivity is a measure of the dielectric constant. Permittivity decreases as additives are used up but will then increase once all additives are consumed. Taken in conjunction with the conductivity values, a clear picture emerges of the changes in the oil.
  • The web based, decentralized monitoring system is perfect for remote or inaccessible locations.
  • Measurements are transmitted via LAN, WLAN or the serial interface.
  • Conceived, developed and manufactured in Germany the WearSens® represents a completely new approach to oil condition monitoring in a variety of applications. For the first time, changes in oil can be detected accurately, online and continuously. The result, optimised loading, reduced wear and cost savings.
• Technical Description:
  • WearSens® - ideal for early fault detection, changes in the machine detected from the start - long before failure states.
  • Applications：
    • Wind turbines, including offshore
    • Oil insulated turbines, including cogen plants
    • Lubricant performance analysis
• Test benches for automotive and marine applications
  • WearSens® detects early changes in the "quality of the machine" from day 1 - before damage occurs. This represents a great improvement on vibration monitoring systems, oil particle analyzers and oil filtration systems which detect after damage occurs.
  • cmc Instruments together with their academic and industrial partners have a thorough understanding of how abrasive wear damage occurs. First, a very small hairline crack appears as a result of roller bearing passage. Oil enters this crack. Localized vibration and temperature rises cause the oil to degrade into oil soaps, acids and hydrogen. The hydrogen then causes embrittlement of the surrounding metal accelerating the possibility of shearing and consequent pitting of the bearing.
  • Premature bearing failures in industrial gearboxes usually result from friction-induced vibration loads due to cracks in the raceway surface.
  • The early detection of critical lubricant states allows preventative maintenance on the transmission - before damage occurs.
  • Early failures of bearings in wind turbines due to surface cracking and subsequent corrosion fatigue represent a technical problem that can lead to unnecessary downtime and costly repairs.
  • Accessibility of offshore turbines presents an even greater problem. The WearSens® sensor system can identify critical operating states early, so that corrective action can be initiated before serious damage.
  • The patented measurement method (Patentnr.: EP 2 163 887 B1, Method and circuit assembly for measuring physical parameters in fluids and their application) combines a high sensitivity at a low noise with a broad measurement range.
  • The electrical conductivity of oil is very low. However, it is possible to measure down to to 0.1 pS/m with the high precision WearSens®. Results are temperature compensated taking into account the unknown and varying amounts of impurities.
  • The web based, decentralised monitoring system is perfect for remote or inaccessible locations. Measurements are transmitted via LAN, WLAN or the serial interface.
  • The WearSens® sensor system was developed in collaboration with the Competence Platform "center for strategic corrosion protection" Prof. Dr.-Ing. Kuipers of the University of Applied Sciences, South Westphalia.
