Advanced Platform / Core Component for the High Speed AUT
Machines and Process Monitoring Systems
ISONIC AUT 16 / 32 are portable multi-channel instruments designed for servicing as the core components of high-speed automatic ultrasonic testing (AUT) machines and process monitoring systems
ISONIC AUT 16 / 32 comprises 16 / 32 identical independently adjustable channels. Each channel comprising pulser, receiver, and 100 MHz sampling rate signal digitizer (A/D Converter) has 2 probe terminals to drive either single or dual element probe or probe pair. The highest scanning speed is achieved through the parallel pulsing, receiving, digitizing, and recording of signals by all channels in use. However in the case of cross-talking through the material is possible the instrument’s channels may be toggled to work sequentially or organized into several groups of few channels working at parallel each (combined mode). The PRF of up to 5 kHz per channel is provided
Superior signal to noise ratio and dynamic range are achieved through firing probes with up to 400 Volt pp bi-polar square wave initial pulse. The duration and the amplitude of both positive and negative half-waves of the initial pulse are tuneable in the wide range. Further it is provided high stability of the firing amplitude selected by an operator within entire pulse width while the leading and falling edges of the bi-polar initial pulse are electronically boosted. Electronic damping circuit provides optimal amplitude / duration ratio for the received signals
Every channel is featured with 3 independent gates; beside regular functions the Gain per Gate Adjustment is possible for each gate – this allows implementing of pulse echo and back echo attenuation inspection techniques simultaneously, interface echo synchronizing, suppression of large geometry echoes, etc
