FERITSCOPE® DMP30
Technical Data
3.9 Technical Data
Description
The FERITSCOPE® FMP30 determines the delta-ferrite content of austenitic and Du-
plex steels using the magnetic inductive test method. All magnetizable structure
sections are captured i. e., in addition to delta-ferrite also strain-induced martensite,
for example, or other ferritic phases. A specific advantage of the magnetic induction
method for measuring the ferrite content is that a sigma phase, i. e., a Fe-Cr precip-
itation, which has formed due to excess ferrite content and unfavorable cooling con-
ditions, for example, is recognized correctly as a non-ferritic structural component.
In comparison, erroneous interpretation of ferrite content is likely in a metallograph-
ic section where a sigma phase is not easily distinguished from a ferritic structure.
Areas of application are onsite measurements, e.g. of austenitic platings as well as
weld seams in stainless steel pipes, containers, boilers or other products made of
austenitic or duplex steel.
Universally
Suitable for measurements according to the Basler Standard
Already from a plating thickness of 3 mm (118 mils) the ferrite content can de-
termine without substrate influence
Various probe models are connectable to the gauges, appropriate to your indi-
vidual applications;
Measurement range, trueness and repeatability are dependent on the connect-
ed probe. You will find this data in the respective probe data sheet.
Uniform, simple and convenient operation
Only one calibration required for entire relevant measurement range from 0.1
to approx. 90 FN; calibration to reference value or by customer-specific cali-
bration standards; adherence to the measurement accuracy specified in stan-
dards ANSI / AWS A4.2M / A4.2:1997
USB and Bluetooth® interface
Compact and robust gauge with aluminium case, protection type IP64 and Go-
rilla® Glass display protector
Battery rechargeable in the gauge or by a separate charger
