Development of Capacitive Position Sensing Geophone for Microtremor System

Abstract:

Low frequency performance of geophone is important when using microtremor system to explore deep geological structure. This paper reports on improving low frequency performance of a geophone by measuring the capacity attached on a conventional geophone, and the consistency of geophone can be adjusted. The design, principal, and performance of the capacitive position sensing geophone are presented. A prototype geophone is designed and manufactured in the laboratory.
