Ultrasonic sensor improves maintenance practices when re-lubricating bearings

Designed for maintenance technicians, the TLGU 10 uses ultrasonic technology to improve manual re-lubrication. When connected to a grease gun, the intuitive device helps a technician to dispense the correct amount of lubricant into a bearing. By overcoming the problems associated with over- or under-lubrication, it can help to extend bearing life. The device is recommended for a range of bearing applications including electric motors, pumps, fans, compressors and conveyors.

  • Easy to use
    The TLGU 10 is supplied as a kit. Combining sound with visual displays helps the technician to re-lubricate with maximum accuracy.
  • Saves cost
    As well as avoiding over-lubrication – and excess grease costs – the added accuracy improves the reliability of a customer’s assets.
  • Increases reliability and accuracy
    Rather than using theoretical models or experience, a technician is given accurate, real-time guidance on the progress of the re-lubrication process.
  • Extends bearing life
    Accurate re-lubrication leads to optimum bearing performance, which reduces the likelihood of wear and failure.

Re-lubrication is critical to extending the life of bearings yet is often carried out based on experience. The TLGU 10 makes re-lubrication a more practical, condition-based process, by delivering the correct amount of lubricant to a bearing at the right time.

The device is simple to use, and relies on a robust, repeatable ultrasound sensor that is optimised for harsh conditions. The sensor monitors the sound of lubricant filling the bearing. Once connected to a grease gun, the TLGU 10 allows a technician to listen to this sound, via headphones. The sound changes abruptly at the point where the correct amount of lubrication has been applied. In addition, a coloured display indicates noise levels for ease of use.

The combination of sound and visual display helps technicians to re-lubricate quickly and accurately – with the right amount. Under-lubrication can cause premature bearing failure or allow contaminants into the bearing. Over-lubrication is wasteful and expensive and can cause serious complications. Both over- and under-lubrication can reduce bearing lifetime.

The TLGU 10 helps technicians to deliver the optimum amount of lubricant in order to maximise bearing performance and lifetime.
