Description

The UDL-M8009 Magnetic Flux Monitor  monitors the presence of rotor flux abnormalities that are caused by the deterioration of the rotor winding.
Operational stresses caused by fluctuating load balances expedite the deterioration of rotor winding insulation in aging machines. Manufacturing and installation defects can also damage the rotor winding in new machines.

The UDL-M8009 Magnetic Flux Monitor is a simple, cost effective, powerful tool that delivers the following benefits:

• Unnecessary expensive and logistically complicated machine re-balancing can be avoided by first identifying if a fault is due to an electrical imbalance as apposed to a mechanical imbalance.
• Safely and confidently delay scheduled rotor winding maintenance based on reliable monitoring data.
• Protects you during the site acceptance phase of new, or recently serviced generators where manufacturing and installation defects that result in damaged rotor winding can be quickly identified prior to accepting the machine.
