The DM Division oers equipment systems based

on passive magnetometer technology. Dr. Friedrich

Frster, the companys ounder, has developed the

Frster-probes (uxgates), which provide the basis

or a wide spectrum o applications such as

geomagnetic measurements or non-d estructive

testing o semi-fnished metallic products and

the resulting fnished components.

Diverse applications.

Precise results.From measuring magnetic elds todetermining coercive eld strength.

INSTITUT DR. FOERSTER has worked or over 60 years to develop magnetic feld

measurement techniques and derive processes or non-destructi ve material

testing. The DM division utilizes this unique expertise to produce highly-sensitive,

precise magnetometers.

This measuring equipment is specifcally developed or the measurement

o magnetic parameters such as ux density, specifc saturation, relative

permeability, and coercive feld strength . In addition to the development,

manuacture, and sale o equipment, the international ly active company

also oers comprehensive services such as training or uture users, service,

measurement equipment calibrati on, and contract measurement.

MAGNETOMAT

The PC-supported equipment system enables high-

resolution magnetic eld measurement or the precise

identication o the direction and magnitude o magnetic

elds. Three-axis sensors are available or the spatial

determination o magnetic elds and can be networked i

required.

MAGNETOSCOP

This easy-to-manage, portable device covers a wide

spectrum o measurement applications based on an

extensive range o probes. These include permeability

measurements or eebly magnetic materials.

KOERZIMAT

The KOERZIMAT delivers reliable data or coercive

eld strength or weight-specic saturation magnetization

on hard- or sot-magnetic components. Specically

congured device systems are available depending

on the application arearom labs to series production.

Absolute magnetic neutralit y is oten a decisive actor in ensuring the usability and unction o materials,

components, and products. It is thereore essential to determine even the minimal presence o magnetic

particles. The MAGNETOM AT is a PC-supported system that measures even the smallest feld strengths

along up to 3 axes, enabling it to detect erritic inclusions or adhesions.

Applications in research and production.Wherever the metal manuacturing and processing

industry requires the highest non-magnetic purity or its

products, the MAGNETOMAT HotSpot technique or

magnetic residual eld measurement is the most precise

and reliable method. It is specically applied to test semi-

nished products (rods, pipes, sheet metals)

and components or magnetic anomalies (hot spots).

The digital 3-axis sensors enable applications ranging

rom laboratory use with a single sensor to complex eld

and component measurements with a large number

o networked sensors. Fluxgate probes transmit the

measurement results to a conventional PC, where theyare displayed by the MAGNETOMAT sotware, saved,

and documented according to job.

At home on oil rigs.

The petroleum and natural gas industries present

some o the most challenging application areas or eld

strength measurements. The exceptional precision

and reliability o the MAGNETOMAT make it standard

measuring equipment in these contexts. To avoid

declinations during directional drilling, the collars on the

drill pipe must exhibit only minimal magnetic properties.

The specication API Spec 7 stipulates exact limits.
