Howdy again bio-netters:
Thank you to everyone that reponded to my request for information on
accelerometers. Following is the edited responses that I recieved.
You may try Omega Engineering. I called them yesterday and asked
them the exact same question. They are sending me their catalogs on
various transducers, including accelerometers. Their number is:
1-800-826-6342
Good luck. Please post any of the other replies that you get.
thanks.

Another source for accelerometers is:
PCB Piezotronics Inc.
3425 Walden Ave
Depew, NY 14043
716-684-0001
PCB has been an excellent company to work with. They have generally been
willing to help researchers with educational discounts and/or equipment
donations when projects are on "shoe-string" budgets.

Fabian,
I bought a Dytran 3016A triax accelerometer for $950 (10mV/G sensitivity) and
power supply $345 and assorted cable $50 about a year ago.

There are many other companies that make all sizes and kinds of
accelerometers:

Here is one company that makes triaxial accelerometers:
ENDEVCO
30700 Rancho Viejo Road
San Juan Capistrano, CA 92675
(714)493-8181

You can contact Analog Devices. They make accelerometers for air-bags. It is about
$50-100 each dependent on quantities.

Hi Fabian:
There are several companies that make triaxial accelerometers. The
subminiature ones are quite expensive. PCB electronics makes some "cheap"
ones. They will run for between $1000 and $1500 for a triaxial set. The
cheaper accelerometers that you are talking about I was told are rather coarse.
In an airbag design you only need to make sure that above a certain
acceleration the airbag employs, so you don't really care what happens at the
lower end. Kistler makes some excelent accelerometers, but they are rather
expensive.
Ben.
Analog Devices makes two models of uniaxial accelerometers. I think one is
model AD50. ONe model has built in amplifier circuits. I don't know their
address, but they are a large semiconductor company.

Try Endevco. They make accelerometers and the instrumentation that
go with them.

Dear Fabian,
Why don`t you check the Danish Company "Bruel and Kjaer" and Kistler.
B&K`s triaxial accelerometers are highly qualified and miniature in
structure. Also one of the netters had came out with the same question
and I have put her responses to my archive, I will send you the responses
in the nearest time.
I wish you success in your work.

We use uni- and tri-axial accelerometers for examining impulsive
loading during gait. We have typically used IC Sensors and Entran
devices, but we are always looking for smaller and/or less expensive
options. I would be interested in seeing the other responses you receive.
I know of two companies that make inexpensive accelerometers designed
for automotive use, but possibly well suited for biomechanics as well.
1. AMP part no. ACH04-08 (about $40 ea.) measures two linear and one
rotational components, with built-in signal conditioning, designed
for higher-g ranges (> 3g, 125 rad/sec*sec). Sorry - I have no contact
info for AMP.
2. Analog Devices part no. ADXL-10, ADXL-50: single-chip monolithic
design, uni-axial, low-cost, with built-in signal conditioning,
DC-1kHz response, 0-10g or 0-50g range, single +5v supply. Contact
Analog Devices (One Technology Way, P.O. Box 9106, Norwood, MA 02062,
USA) at (617) 329-4700.
We have no experience with the AMP device, but we have experimented a
little with the Analog Devices chip - it looks pretty good so far. We
have talked about trying to assemble a small triaxial system with 3 of
these, but we haven't done anything about it yet.
If anyone has experience with the AMP device, I would be interested in
hearing about it.
