Strain gage readout.

Archiver

I need to analyze a series of "pulses" and readout in real time parameters
such as the integral (area under) of each pulse, total intergal for a series
of pulses and the average value of these areas over a few pulses. The pulses
are generated from a force being applied to a cantilevered beam which is
indicated by a strain gage.
I plan to use a wheatstone bridge configuration to produce a voltage change
proportional to the resistance change in the gage. Can anyone advise if
there already exists similar circuits or a circuit which may be suitable as a
starting place?
I have purchased both BS1 and BS2-1c's.
Thanks.

It is not easy to readout the output from strain gage connected to create
the four leg of a wheatstone bridge configuration.Overall outputs of less
than 1mV on common mode voltage of 5 volts may be encountered.
You need a special kind of ins.amp. or A/D.
