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.

The company offers a complete range of machines and tooling for applications ranging from 1 / 8 " light wall tubing to 8" pipe.

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 UFD40 system accommodates two independent measuring channels in one IP 65 module enclosure

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

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
