SoMat 200 Field Computer System. The SoMat 2000 is a small self-powered
data acquisition computer that can be adapted to "ride" on a rotating shaft
or other moving device while it is connected to and recording data from
transducers such as strain gages. After a typical test run, the machine
is stopped and the acquired data is off-loaded to the notebook PC for further
processing and backup. As an example, strain gage data can be recorded
and processed by an FFT algorithm to result in a spectrum plot of strain
vs. frequency. The significant frequencies at the strain gage locations
can be resolved as well as the strain time history data.

Also used for data processing and graphics generation.
Wavetek l00A Mini-Analyzer vibration analyzer. The analyzer receives a
signal from an accelerometer mounted on the machine and processes the signal
to produce time history acceleration and frequency domain results of acceleration,
velocity or displacement. Results are plotted on the spot by a HP7470A
pen plotter.

flow fan impeller (courtesy Joy/Green Fan, New Philadelphia, OH). Joy utilizes
strain gage test results to verify stresses and blade frequencies calculated
using finite element analysis or other analysis methods.
