Transducers for high pressure

"For extreme conditions (high pressure, high temperature) the acoustic adaptation layer with a kind of Lambda/4
matching can be replaced by thin metall sheets of e.g. Aluminium and copper or steel. Both can represent a spring/mass system tuned to the resonant frequency of the piezoceramic.The bonding between the sheets can be oil or at higher temperature glaspowder.
You may find some description of tbis receipe at K. Matthies.(BAM-Berlin)
Concerning your demand for a software to calculate the behaviour of such layered probe systems, I would like to draw your attention to a quadrupol software model which is used at BAM and at other places developped by the author of those lines. The program package is available at BAM.
It calculates for a given thickness mode piezoceramic element together with an unlimited number of matching layers, with attenuation loads and with tuning inductances and cables the spectrum and pulse response for a Dirac pulse excitation.

HUNDER(tm) - Taking the Industry by Storm!

Face International Corporation of Norfolk, Virginia has begun sale and
shipment of its revolutionary THUNDER Actuators and Sensors to leading
researchers, technology developers and product innovators across the
country. With a variety of THUNDER devices from which to choose, FACE is looking
to identify additional buyers interested in establishing a strong
competitive position for their organizations on the leading edge of this emerging
technology.

FACE is the premier manufacturer of these powerful new THUNDER
Actuators and Sensors, invented and patented by NASA. In addition,
FACE's licenses from NASA give the company the capability of providing
certain significant competitive advantages to FACE's THUNDER clients.

Winner of a 1996 R&D 100 Award, THUNDER technology introduces
a versatile family of ultra-high performance piezoelectric devices with
the promise of significant benefits to numerous applications...from motion
control to ultrasonic imaging, pump and valve products to position and
flow sensing. Thanks to a novel manufacturing process, THUNDER devices offer

a number of important advantages over conventional technology: very high
displacement, substantial force, ruggedness, reliability, energy
efficiency...and they're relatively inexpensive.

As sensors, THUNDER devices produce an extraordinarily high output
voltage, thus simplifying system design by reducing the need for
amplifiers and filters. These are tough, durable, solid state devices
that can be custom designed and fabricated to meet a wide variety of
dimensional requirements or performance specifications.

We would like to provide you with further information about our
THUNDER Actuators and Sensors and about the capabilities of Face
International...both as a manufacturer and as an important R&D resource.

Would you please advise as to the best contacts within your organization
and their mailing addresses?

In the meantime, please check out our new website at www.faceco.com
for the latest in product information and laboratory data.

Thanks Very Much

Sincerely,

Allison Clay

SITEX CPSERIES

Teledyne ICM’s CPSERIES has been designed with a view to revolutionizing the handling and perfor
...
mances of portable X-Ray sets. Despite having managed to halve the weight of similar portable X-Ray generators available on the market (while continuing to provide the same power output), the SITEX CPSERIES generators feature a shutter, a laser pointer, a beryllium window, an aluminum filter and two integrated diaphragms (customized sizes are available upon request). Without compromising the robustness and reliability for which ICM products are renowned, the small size and light weight of the SITEX CPSERIES will radically change the way that you perform your RT inspections. And you will see a positive impact in terms of both quality and return on investment (ROI).
