FERITSCOPE® FMP30 Measurement of the Ferrite
Content in Austenitic and Duplex Steel
|
|
|
Chemical, utility and other processing plants
are often exposed to heat, aggressive media
|
|
|
and high pressure. These circumstances require
corrosion and acid resistant steel that is
|
|
|
mechanically resilient even at high
temperatures. If the ferrite content is too low, the weld is
|
|
|
susceptible
to cracking under heat, if the ferrite content is too high, the weld loses
its toughness
|
|
|
and ductility. For duplex steel, a lack of ferrite
in the area of the weld seam is an indicator of
|
|
|
susceptibility to cracking under
tension or vibration.

|
|
|
|
Characteristic features:
|
|
|
Non-destructive measurement of the ferrite
content in a range of 0.1 to 110 FN or 0.1 to 80% Fe in austenitic and duplex
steel
|
|
User-friendly instrument operation
|
|
Large display, rich in contrast with 240 x
160 pixels
|
|
USB port for data transfer to PC or printer
|
|
Mechanical sliders to cover keys not required
for the measurement operation
|
|
Ready to make measurements right after power-up
|
|
Measurement automatic upon probe placement
through external trigger via instrument button or PC
|
|
Automatic probe recognition
|
|
Audible signal at measurement acquisition
|
|
Only one calibration required for the entire practically
relevant measurement range from 0.1 to about 90 FN. Measurement accuracy
according to ANSI/AWS A4.2M/A4.2:1997 standard
|
|
Calibration with standards traceable to TWI
secondary standards or with customer-specific standards
|
|
Adjustable instrument switch-off or continuous operation
|
|
Lockable keyboard/ restricted operating mode
|
|
Various status displays (e.g., warning message when battery
voltage drops)
|
|
Various language settings
|
|
Measurement units selectable between WRC-FN and %Fe
|
|

|
|
Up to 100 applications for measuring application specific
calibrations
|
|
Capability of allocating readings into up to
4,000 blocks
|
|
Date and time stamp for blocks

|
Display of statistical common characteristic
values such as mean value, standard deviation, min, max, range in the block
and final results. Output of characteristic variance-analytical values
|
|
Graphical measurement display as a histogram with a
Gaussian plot
|
|
Capability of entering process tolerance limits
and computation of the associated process capability in dices cp and
cpk
|
|
Audible and visual warning when tolerance limits are
exceeded
|
|
Free-running display with additional
presentation of the reading as an analog bar between the tolerance limits
|
|
Matrix measuring mode for connected multi-point
measurements, e.g., in a pre-defined surface array
