Roland Electronic GmbH,
Germany, has launched the
newly designed digital UFD40
system as a successor to the
analogue UFD detector. The
system has been designed
to detect faults, butt welds
and mechanical connections
in small tubing, wires, and
cables made of metallic
materials such as steel,
stainless steel, copper, brass
and aluminium.
The system is based on the eddy current
measurement principle. The material to be
monitored passes through the opening of
an encircling coil sensor. Roland Electronic
offers sensors suited to materials ranging in
diameter from 1 – 90mm.
The UFD40 has features typically available
in classic eddy current fault detection
systems designed for automated production
processes. These include adjustable fre-
quencies, high and low pass filters, and
y-component and vector analysis, making the
system suitable for monitoring many different
discontinuities with one type of hardware.
The system features a modular design and
several operating modes. The complete
electronic circuitry for two independent
measuring channels is housed in one IP 65
module enclosure. Each channel executes
the measurement functions completely
automatically.
An RS232 interface provides connection
to the host PC, which serves as t e
operating interface for the system and
provides visualisation of all measurement
values. Both measuring channels function
autonomously, allowing the disconnection
of the host PC. Alternatively, a parallel
interface or a fieldbus interface are
available for communication with production
equipment PLC.
