Possible applications

The DT-156 is an extremely compact and very versa-
tile measuring instrument, which has been specially
developed for the fast, precise and non-destructive
measurement of coating thicknesses . The main appli-
cations lie in the field of protection against corrosion .
the BB 20 is extremely well suited for a wide variety of
applications and is ideal for manufacturers and their
customers, for offices, surveyors and experts, for paint
shops and galvanising operations and for the chemi-
cal, automotive, shipbuilding and aircraft industries . In
addition, the ergonomically formed appliance is parti-
cularly well suited for applications in light and heavy
mechanical engineering, in laboratories, in workshops
and outdoors . The sensor exploits two physical princi-
ples . It works according to both the magnetic induction
and the eddy current principle . The sensor measures
the coating thickness on both ferrous/ferromagnetic
and non-ferrous substrates and can also be used for
special tasks, e .g . for particular geometries or on ma-
terials with special characteristics .

Appliance description

The BB 20 works according to two different principles,
depending on the substrate: the measuring instrument
uses the magentic induction principle for measure-
ments on ferrous materials and the eddy current prin-
ciple for measurements on non-ferrous substrates .

Operating manual – layer thickness measuring instrument BB 20
The measured values appear together with further
user information on the easily readable display . The
display is equipped with background lighting, which
facilitates reading under poor lighting conditions .
There are two different modes of operation: DIRECT
mode and GROUP mode .
It is recommended that you use the DIRECT mode for
individual, fast measurements . This mode supplies
information for statistical analyses . No individual va-
lues are stored . The program can analyse up to 80
measured values .
GROUP mode allows the user to store the measured
values in a freely configurable memory . Up to 400
measured values and 4 series of measurements can
be recorded and analysed according to certain criteria .

Scope of supply

1x measuring instrument for the determination of the
coating thickness on various substrates, 2x 1.5V bat-
teries, plastic carrying case, user manual, steel and
aluminium baseplate including different film thick-
nesses for calibration .
USB cable
CD for Windows 98/2000/XP/Vista/Windows 7

Sensor

The sensor rests on contact springs in the sensor bus-
hing . They are intended to ensure that the sensor is
protected and correctly positioned and applied with
the same constant pressure . A V-groove in the bus-
hing ensures that measurements performed on small
cylindrical parts are reliable and accurate . The tip of
the sensor is made of a hard and durable material .
Hold the sensor against the measurement object via
the spring-loaded contact bushing .
To measure, press the appliance with the spring-loaded
measuring tip against the surface to be measured .
