Innerspec specializes in NDT products and services that demand unconventional means and high levels of performance such as:- Inspections of difficult materials such as cast steel, cast iron, austenitic stainless steel, coated and painted surfaces.
- Inspections in extreme environments such as cryogenic freezers (-100ºC), furnaces (+1000ºC), radioactive vessels, and deep space (vacuum).
- Integrated inspections at high speeds without disrupting production.
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:

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:
The power output at different frequencies for the 8kW and 20kW pulsers are shown on the tables below:
Typical output currents and voltages 8Kw RF pulser at 1.5Mhz.

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.
