MFD900. The most industrial ultrasonic test system for flaw detection and thickness measurements

Transcription

1 MFD900 The most industrial ultrasonic test system for flaw detection and thickness measurements Guaranteed the lowest possible down time over many years. Pure ultrasonic testpower for high speed off- line and in line testing * Combines the best of analog and digital techniques * Very easy to use and quick system integration * Local and remote control

2 MFD900 The only computerized system in the world that keeps working even if its central computer would fail Each MFD900 channel is a complete independent flawdetector / thickness tester with individual outputs, constructed as a plug-in module from the rear of the system. Replacement - if needed - can be done in the field by non specialized personel. The central computer module is also field replaceable in case of service. As the computer section is only used for external communication, for the display and to set up the channels, the individual channels remain operational including their outputs in case the computer section would fail. This guarantees the lowest possible down time over many years.

4 GENERAL: The MFD900 has been designed for flexibility, ease of use and efficiency. Quick field service possible by its modular design Optimal test results are achieved using a combination of hardware and software techniques to obtain the highest performance in test speed and reliability. The MFD900 can be supplied as a 2 channel system for research, production or C-Scan applications or with 10 module each equipped with a second pulser receiver. It can also be supplied as a multi channel, multiplexed or a combination of both systems for ultrasonic testing up to 30 MHz. Easy integration by direct accessible analog outputs of signal amplitude and dual TOF (thickness) of each channel as well as digital alarm outputs of all gates and alarm conditions. Outputs can be configured to customers requirements Very high power square wave pulsers Very low noise resulting in high sensitivity. Various noise reject filters built in. Directly accessible I/O module. User defined input /output to control external alarms, auxiliary functions, inputs with switch buttons, PLC in- and outputs etc.

5 POSSIBLE CONFIGURATIONS: Each single ultrasonic channel can be equipped with a second pulser/receiver module which makes it a dual channel multiplexed unit. Most parameters and gate settings in this multiplexed mode are yet independent for both pulser/receivers which allows a high freedom for various applications. One mainframe of the MFD900 can be equipped with 10 channel modules working in parallel at full prf speed. When each channel is equipped with a second pulser/receiver it contains 20 channels. Optionally it is possible to work with 4 channel multiplexed modules when speed is less important, making it an even more economic system. Applications: Thickness and corrosion inspection. Measuring with contact or immersion transducers ID/OD. Measuring water path from transducer to front wall for dimensional measurements as well as wall thinkness Weldinspection including a couplng check phase of the transducers for 100% reliability. Working with most of customers own transducers. Non couplant testing with airprobes with external probe adapters. Billet testing with large transducers
