  • High-Power Toneburst Output: Capable of producing RF tonebursts up to 5 kW, ensuring clear signal detection even in challenging materials.
  • Phase-Sensitive Detection: Provides precise amplitude and phase measurements, enabling exceptional accuracy in ultrasonic testing.
  • Superior Signal Processing: Equipped with superheterodyne receivers for noise rejection and high-resolution timing for accurate transit time measurements.
  • Distributed by Sonemat for Local Support: With Sonemat’s expertise and customer support, integration and maintenance are straightforward, ensuring maximum performance.

The instrumentation for this sophisticated, complete ultrasonic system has been divided into functional modules. Each module performs a specific task and can be understood, tested, and modified individually. The system consists of the following elements in conjunction with the RAM-5000 power frame:

• Broadband, high-power gated amplifiers for producing RF bursts, derived from the CW source, to drive various types of transducers, including piezoelectric, air-coupled, and electromagnetic acoustic transducers (EMATs).
• Timing module to produce the gates required to turn the amplifier on and off coherently with the CW source.
• An accurate direct digital synthesizer (DDS) for high-resolution frequency control and the ability for rapid frequency sweeps.
• A broadband receiver stage to amplify ultrasonic signals, either from the transmitting transducer via a diplexer or from a separate receiving transducer.
• The broadband receiver is typically followed by superheterodyne phase-sensitive receiver stages to improve the detection of received signals in noisy environments.
• A pair of integrators that are gated on and off to process the information from the phase-sensitive receiver outputs for precise measurements of the phase and amplitude.

Configurations (Marks):

• • Mark I: Basic configuration with high-power gated amplifier and power frame; requires an external RF source.
  • Mark II: Adds timing functionality, allowing coherent gating of RF signal for more controlled pulse generation.
  • Mark III: Fully computer-controlled toneburst pulser with an integrated synthesizer.
  • Mark IV: Includes a broadband receiver module for enhanced signal detection in addition to toneburst generation.
  • Mark V: Adds superheterodyne mixer and phase-sensitive detectors, enabling digitized phase detection for detailed analysis.
  • Mark VI: Complete superheterodyne phase-sensitive measurement system with all six elements, offering full amplitude and phase measurement capabilities.

Applications :

• • Flaw detection in metals, composites, and high-density materials
  • Material characterization for research and industrial quality control
  • Acoustic property analysis and time-of-flight measurements
  • Ultrasonic testing in high-precision industries such as aerospace, automotive, and energy
