Dear Dave,
Thanks for your interest, and I have sent you a private message.
In addition to our shock recorders, I suspect our DC voltage loggers would come in handy to many teams. We offer them in single, 4, and 8 channel units, and in ranges from ±100mV up to 30VDC (the 15V range would be ideal for monitoring anything from teh 12V battery on down).

We also have pulse recorders that might tie in well with PWM's, ultrasonic ttransducers, or anything else with a dry contact output. The Pulse110 samples at 1KHz and totalizes the results at a user-specified rate of 1 second or slower.

We have engineering units built in to the software (and even programmible into the logger) that automatically convert pulses into units that make sense to your application. One great example of this in action is our Wind Speed recorder, which is a reed-switch anemometer tied to a pulse110 preprogrammed to give average wind speeds at 10 second intervals:

All of these loggers can be communicated with using a single interface cable, which comes in serial or USB.

I look forward to answering any application questions that relate to our full line of data recording products.
