Main Features

Sonia Violet is a ultrasonic module compatible with SONIA architecture designed to drive high frequency probes. This module has 1 UT channel with high bandwidth, intended for applications in the field of inspection of thin components, ultrasonic microscopy, materials characterization, etc…

UT channel, single crystal probe.
Pulse-echo technique.
Bandwidth from 4 to 200 MHz (probes from 10 to 150 MHz).
High speed negative spike pulser with two energy levels (low & high).
High digital signal processing capabilities (filters, gates, signal types, etc…).
2 different electronic units: main unit and remote pulser-preamplifer, able to work underwater. The maximum cable length is 3 meters.
Small size that permits to minimize the length of the transducers cables, digitizing the UT signal very close to the transducer. This implies lower UT signal distortion, attenuation and noise.
Replace the analog communication lines by digital ones, immune to electromagnetic interferences (fiber optic), which means no signal distortion and/or noise in the transmitted signals and performance independent of installation layout.
Low power consumption. The electronic boards are sealed in non ventilated rugged enclosure.
