Roland Electronic has extended its
expertise in eddy current measurement
to a new product programme to cover
the detection of defects, butt welds and
mechanical connections in wires, cables
and small tubes. The new UFD40 system
is specifically designed for continuous
process control in production.
The UFD40 has all the features of eddy
current testing equipment used in
automated inspection lines, such as
variable operating frequencies, high
pass and low pass filters, y-component
and vector analysis. This makes it
possible to configure the same hardware
specifically to the inspection task under
consideration.
The measurement is based on the
eddy current principle whereby
the wires and cables pass through
encircling coil sensors in the continuous
production process. The sample rate of
the measurement is 15kHz; materials
passing the sensors at 10m/sec result in
a resolution of 0.6mm in length.
The system features a modular design
where the host PC is separate from
the measurement channels. Complete
electronics for up to two measurement
channels are accommodated in a
separate module enclosure (IP65). Each
channel is completely functionally
independent: measurement, analysis
and real-time communication with the
host PC can be used for visualisation
of the results and for configuring the
connected measurement channels.

Universal fault detector
LaserLinc has launched the ProfileVu
micrometer fixture that pivots up to 180
degrees to allow continuous inspection.
It is designed for use in finding width
and thickness of non-circular products,
such as flat wire, and for locating
thickandthinsectionsofextrudedmaterial
and other die-formed products. Users
can mount one or two compatible Laser-
Linc laser micrometers to the ProfileVu;
the TLAser122, TLAser222, TLAser230,
Triton312, and Triton330 are suitable.
Using three-axis micrometers (providing
six-axes of inspection), the angle of
rotation and the cycle-time required to
identify the dimensions of interest are
significantly reduced.
The fixture’s angle of rotation is
adjustable from four up to 180 degrees,
and it completes a rotation of 180
degrees in up to four seconds (speed and
rotation are dependent on the material
to be inspected). The angle of rotation is
managed by an easily configured PLC.
Combined with a Quadrature encoder, the
ProfileVu system can correlate diameter
(or other laser scanner measurement)
with the angle of measurement, giving an
accurate picture of the product.
Power requirements are 110–240V
AC, 50–60Hz; the unit has a one-year
warranty. The Zero Latency encoder input
is part of Total Vu software.
