Ultrasonic
PC Boards
Mistras Group Hellas
offers a variety of state-of-the-art UT boards (Analog/Digital
AD Boards and Pulse/Receive PR boards) which can
be fitted into any PC and convert it to a powerful UT system,
with the appropriate software (UTWin). The AD boards can be used
separately as a custom Data Acquisition system as the boards can be
supplied with Lab View software and drivers so that customers can
develop their own acquisition system for specialized uses. Typical
applications are:
AD-IPR-Express-4
The AD-IPR-Express-4 is a full UT system on a 2/3 sized PCI Express
Card. It includes a pulser/receiver, 250 MSPS, 14-bit analog to digital
conversion (available in 1, 2, or 4 channels), and motion control. With
a conversion rate of 250 MSPS and 14 bits of resolution, the signal
processing is fast and precise, opening the door to a wide range of UT
applications. The integrated motion control enables control of up to 4
independent or synchronized axes and 4 encoders for motion feedback.

AD-IPR-1210-PCI
(12-Bit Digitizer)
A 12-bit analog to digital converter with an integrated high-performance
300-volt (400 optional) pulser/receiver module. A 10-layer SMT printed
circuit board creates a low-noise, high-speed PCI-bus card designed for
wide bandwidths, yet fits into one standard PCI slot. Available as an
integrated unit or as a stand-alone (analog/digital only board for use
with other internal or external pulser/receiver options).
Key Specifications:
-

ARB-1410
Arbitrary Waveform Generator
A PCI-bus based, highly precise (14-bit), high-speed (100 MSample/
second) unit that generates an extensive variety of simple or complex
arbitrary waveforms. The board uses DDS frequency synthesis to generate
an analog output waveform and the entire system is housed on a single
PCI card. It features selectable smoothing filters with an optional
high-voltage amplifier (+150V) and optional output multiplexer for
sensor arrays.
The ARB-1410 is ideal for use Acousto-Ultrasonics instruments like the
T-SCOUT™, to synthesize waveforms for Acousto-Ultrasonics signal
generation or Guided Wave Inspection.
1616
UT Node
This single channel pulser/receiver (P/R) node has a 4-channel
multiplexer for four single or dual-crystal transducers.
The receiver has 12-70 dB gain with 200 kHz - 20 MHz bandwidth. The
pulser is square wave 10-50v. Wireless communication between the node
and other software/hardware components is possible using Zigbee or Hart.
An SD memory card or data logger mode optimizes data acquisition and
storage.
The 1616 UT node is also ultra-low power with a two-year battery life
possible at one measurement per day. It's designed for
intrinsically-safe certification and use in the oil & gas and
petrochemical industries.
