Programmable Accelerometer Conditioner Integrator

Abstract

Ground motion studies rely heavily on the Sandia DX velocity transducer. This report describes an analog circuit which may be used with a piezoresistive accelerometer to produce velocity data. The circuit may also be used to amplify and calibrate accelerometer outputs. It is programmable in that microswitches are used to change the gain and the low frequency roll-off point. The integrator is DC coupled, but it does not saturate with DC inputs. The results of laboratory tests and field test comparison are described. It is concluded that any integration schemes for producing velocity from acceleration data should be applied after the acceleration has been recorded and the final signal-to-noise ratio established. An improved routine for processing acceleration data is suggested.
