High-Power UT Instrumentation

Conventional ultrasonic instrumentation has been designed to provide good performance with conventional piezoelectric transducers that enjoy a high-degree of efficiency when properly coupled to the material.

However, there are techniques and applications where very high voltages and/or long bursts of energy are necessary to produce the desired outcome, including:

  • Non-contact techniques such as Electro-Magnetic Acoustic Transducers and air-coupled ultrasound.
  • Highly attenuative materials and low-frequency applications.

Innerspec has patented a unique pulser topology that permits outputs in excess of 20kW of power in frequencies ranging from 50kHz to 20MHz. The advantages of these pulsers include:

  • Large power density.
  • Optimum power over a wide range of frequencies.
  • High efficiency (>93%) with minimum heat dissipation needs.

Innerspec uses 8kW and 20kW pulsers in their high-power temate® instrumentation as shown in the table below:
