With its magnetic sensor head the Portamonitor™ is attached to the outer casing of machinery and takes readings over a short period to assess the condition of the moving parts within. It achieves this by measuring the Ultrasonic signature given off by the bearing as it is in operation.

  • Decibel Level – the decibel reading is used for longer term condition monitoring with readings taken periodically and compared to previous readings to chart how specific bearings are degrading over time. This allows for predictions of potential failures and helps avoid expensive failures by building a very easy preventative maintenance scheme into existing procedures
  • Distress Level – The distress level offers an ideal solution for visiting Superintendents onboard or sporadic testing as it provides a rough indication for the current condition of each bearing over a 0 – 40 scale. If a bearing consistently measures over 10, action of some kind is required to lubricate, examine or repair that specific machinery.
