Abstract

The objective of this work is to present an inexpensive alternative to traditional accelerometer and DAQ components for machine condition monitoring. This paper explores the feasibility of using a PC sound card for high bandwidth data acquisition from an epoxy-sealed electret condenser. This sensor's frequency response will be contrasted against that of a commercial piezoelectric accelerometer amplified and sampled by a traditional DAQ system. The frequency response of the sealed electret accelerometer is shown to be a linear function of acceleration input magnitude. As a result, the electret accelerometer is capable of replicating the response of the piezoelectric system through frequency deconvolution. An evaluation of the sensor's capabilities and possible applications are discussed.
