Magnetic Field Monitoring MFM-035




The Magnetic field monitoring MFM-035 is specially designed for Rütten Magnetic Agitator® System and part of the Rütten Sterile Storage System (SSS) for production and handling of sterile liquid pharmaceuticals and by-products.


© Challenge

Validation is requiring a proof constant mixing to show that the magnetic agitator is really rotating.

© Application

The Magnetic field monitoring MFM-035 is measuring and checking the magnetic field generated by the agitator bar and agitator drive. The panel is indicating the agitator speed and locked or slipping magnetic agitator.

© Background

The MFM-035 Magnetic Field Monitoring System analyzes magnetic fields in the surroundings of magnetic agitators.

During normal operation (left), the system measures the actual RPM of the magnetic agitator.


Is the magnetic agitator locked or slipping, the system detects the anomaly in the magnetic field (right) and reports the error.

© Construction

The system is mainly consisting of the magnetic field sensor built-in in a stainless steel housing and panel. The magnetic field sensor and the panel are attached at the Rütten Magnetic Drive®.
