The new design RDG 2000-2500-2500S digital flaw detectors are equipped with a high bright- ness screen for A-scan presentation and an op- erator interface via dedicated keyboard and video displays set around the special wave- forms panel. With different measurement methods available, special functions, an internal data logger, and complete output ability, the RDG 2000-2500- 2500S detectors are the most versatile of the new generation.
The high protection IP67 allows the use in workshops and construction sites being pro- tected against water and oil. RDG 2000, 2500 and 2500S can be used DAC or TGC and AVG/DGS curves. The DAC curves, which can be drawn on 10 points, can be selected on 3 level (0, -6, -12dB and one custom)with the possibility to read echo height respect to the selected curve. The AVG/DGS curves, for straight probes (e.g. DP25/2, DP25/4 and DP10/4) allow evaluation of the flaw equivalent diameter even when at- tenuation or transfer losses occur. The LCD colour TFT 7” display with adjust- able brightness, can work even in unfavourable light conditions.
Flip monitor function allows the automatic screen rotation depending on the handle opera- tor (hand right/left).
The new RDG 2500S ultrasonic flaw detector can automatically interface with the multi- transducer rotating probe dedicated to specific control of solid axles for railway field. It is configured to load calibration of the transducer selected by the switch on the rotat- ing probe. Each calibration panel recalled is identified by a message show on the display. Amplitude and depth analogical ouputs, video output (S-video) and a USB port are provided to be connected to PC. A optional software program operating under WINDOWS, is disposable to download to PC, calibration panels (100 memories complete of notes), defect (A-scan 1000) and thickness data (10000) stored in the unit (4000 for RDG 2000).
The very easy interaction with the operator, the very low weight (1.6 Kg with battery), the small size and the high battery life (> 14h) identify the RDG as a very versatile and useful tool for the ultrasonic general inspection.
