What DO both instruments have in common?• an LCD A-Scan Display, providing various display modes• Display Set Functions (Delay, Range, etc.) • Set Functions for Gain, Sound Velocity, Frequency Ranges, Rectifier, • Multiple Gates (including Gate-B triggered by Gate-A)• Multiple Thickness Indicators• Tolerance Monitors for Min and Max values• Echo Freeze Mode• Storage for Instrument Settings• Data Logger/Recorder• Remote Control by and Data Transfer to/from a PC via RS 232

It is not easy to determine the real differences between Flaw Detectors and Thickness Gauges having an A-Scan Display...

A USM 35X costs @ $11,500.00A DMS 2 TC costs @ $7,500.00 ________________There is an attractive price difference of @ $4,000.00

Why not buy a DMS 2 TC as a Flaw Detector?

What is UNIQUE for a Flaw Detector?

• Prepared for universal US Applications• connectable to ALL probes of all types and Frequencies • More Precision in Display and Gate Parameter Settings• Transit Time AND Amplitude evaluation (DGS, TCG, CGB, AVG,

DAC)• High Pulse Repetition Frequency for (Semi)automatic scanning• Prepared for special Echo-Analysis (Time --> Frequency domain)• Prepared for a better acoustical Resolution (between 2 Echoes)

What is UNIQUE for a Thickness Gauge with A-Scan Display?• Specialized for Full Range Thickness Measurement Applications (independent of

Display Setting) • Dialog Probes are Recognized for a better Documentation• Individual Breakpoints and V-Path Correction out of Dialog Probes• On-Block Zeroing Procedures for Delay Line Temperature Compensation• Off-Block Zeroing for Bad Material Surfaces• Dialog Probes are able to store individual Parameter Settings like Gain, Filtering,

Main Bang Blockout (Gate), Thresholds• B-Scan, Auto-V and TopCoat for Thickness Measurement without knowing the

Sound Velocity• Automatic Amplitude regulation during Peak Measurements• Only 4 small AA Batteries for 40 hours Operating Time (due to low PRF) • Data Recorder with several Structures including A/B-Scan Attachments

Why is a Thickness Gauge with A-Scan Display not a Flaw Detector?

• It cannot use any Type of probe: eg. NO angle beam probe• No Distance Amplitude Correction on Board• No Amplitude measurement and/or evaluation• Risk of missing Flaws during (Semi) automatic scanning • No evaluation of Echo Forms
