ECHOMAC^® II

Echomac^® II: Advanced Ultrasonic System for Flaw Detection, Dimensional & Thickness Measurement in Tube, Bar, Plate & Weld

Versatile, high-performance ultrasonic tester designed for modern NDT requirements

Echomac^® II builds on MAC’s proven legacy of ultrasonic testing excellence, offering enhanced signal fidelity, precision control, and advanced real-time processing—all in a flexible, user-friendly platform. Designed for full volumetric inspection of tubes, bars, plates, and weld zones, the Echomac^® II system is ideal for high-performance applications in industries such as aerospace, nuclear, automotive, and metals production.

Key Features & Capabilities

• High-Precision Flaw Detection
  Detect longitudinal, transverse, and off-angle defects with real-time signal processing and configurable alarms for up to 32 independent channels.

• Simultaneous Dimensional Measurement
  In three-transducer mode, the system simultaneously measures OD, ID, and wall thickness with superior resolution—better than 1 µm for steel in PR mode. Eccentricity and ovality evaluations are also supported.

• Advanced A-Scan Visualization
  Flicker-free, full-color oscilloscope displays with multiple modes (FE, PHE, NHE, RF) offer vivid signal clarity. Persistence and decay functionality help highlight transient or infrequent defects.

• Digital Strip Chart & Reporting
  Real-time strip chart logging for each gate and channel with summary reports at the end of each production run. Monitor and record defect events, part counts, reject rates, and traceability data.

• Optimized Pulse Control & Gating
  Fully adjustable pulser (0–225 Vp, 30–500 ns) with configurable damping and delay. Four measurement gates and one interface gate with independent setup per channel.

• Robust DAC Functionality
  Supports up to 15 DAC segments per channel with intuitive graphical setup. Combined gain up to 100 dB enables precise evaluation of amplitude-distance characteristics.

• Seamless System Integration
  Interfaces with rotary, squirter, bubbler, and spin-the-tube setups. Fully compatible with MAC’s Echomac^® Rotary Transducer Assemblies and existing NDT infrastructures.

Technical Highlights

• Frequency Range: 0.6 to 27 MHz (-3 dB)

• Receiver Gain: 0 to 100 dB (0.1 dB steps)

• Digitization: 100 MHz, 8-bit, per channel

• Pulse Repetition Frequency: 10 Hz to 20 kHz

• Data Communication: 1 GB Ethernet, TCP/IP protocol

• Alarm Logic: Configurable for peak/valley, positive or negative threshold detection
