IrisPower FluxTracII-S 4208

Continuous online Rotor Magnetic Flux Monitor

The FluxTracII-S 4208 is continuous monitor to collect and analyze flux data from any flux probe in real time, providing the user with data on rotor winding shorted turns.

Works with These Assets


  • Accepts Total Flux probes (TFProbe) and other flux probes
  • Inputs for shaft sync sensor (Keyphasor) for pole determination when shorts are detected
  • Monitors up to four machines (option)
  • Monitors 4 to 128 poles per machine
  • Provides relay contact to alert user
  • Data compatible with RFAII-S portable instrument
  • Storage for baseline, latest set of non-alerted measurements and the latest set of alerted measurements
  • Multiple communication ports: USB, Ethernet
  • Measurements can be locally or remotely downloaded to a computer with RotorFluxProTM software
  • Modbus TCP/IP protocol available for built-in server and client capability, for data interchange with third party systems

Group Created with Sketch. Applications

Flux monitoring relies on measurements of the local magnetic field emanated from each rotor pole. Factors affecting the magnetic field from each pole

  • Air-gap size change
  • Rotor out-of-round or off-centre
  • Loose pole – key migration
  • Stator migration
  • Natural variations of pole’s physical position
  • Shorted turns on a pole
