IO-Link vibration monitoring

Simple to implement industrial-grade machine vibration condition monitoring

  • Easily protect your machinery from damaging conditions.
  • Automate your machine condition monitoring with real-time indicators of impact, fatigue, friction, and temperature.
  • Seamless integration directly into Industrial Ethernet systems via IO-Link.
  • No control cabinets or extensive wiring required for installation.
  • Leverage your existing control network for process and Real-time Maintenance.

Industrial-grade machine protection integrates directly into your existing control platform. Machine condition is continually monitored for common fault conditions of impacts, component fatique, and friction. This allows timely and predictable scheduling of maintenance before major damage or failure and production downtime. Machines are continuously and permanently protected, unlike when using intermittent single measurement monitoring systems.

  • Simple installation
  • Accurate equipment condition assessment
  • Automated alerts
  • Root cause analysis tools without the complexity and high price

Measurements

The VV design aims to simplify the primary categories of machine failure. Unlike typical single measurement systems, the VV simultaneously monitors equipment for the four categories of machine problems: impact, fatigue, friction, and temperature. The embedded IO-Link technology provides this data in real time, giving the VV sensor the capability to predict pending failures and mitigate catastrophic damage.

Monitoring methods

Each VV sensor comes with factory-set alert outputs optimized for out-of-the-box performance based upon machine size and speed. Alarming thresholds adhere to recognized standards (ISO 10816) and ifm’s years of machine monitoring experience.

Location of sensors and monitoring methods

Typically, we recommend mounting sensors radially to shaft rotation to detect the greatest level of movement and located mechanically as close to the target as possible. The orange dots in the images indicate approximate sensor location.

When applying real-time continuous monitoring, 3-axis measurements are typically not needed. 3-axis techniques are typically used in traditional route-based analysis methods where only a snapshot of the machine health is recorded. In some cases where machine design implements axial loading, a second axial sensor may be necessary.

Integration

The VV family is flexible enough to provide varying degrees of control so it can scale as your level of IIoT integration grows. From sensor to ERP.

Stand-alone switching
With a 24 VDC power supply, the VV provides simple switching outputs for machine control and / or local indication of machine status.

IO-Link system
Adding sensors to your existing IO-Link network provides a quick way to achieve Industry 4.0, IIoT and RtM.
