Abstract: The temperature influence on parameters of a geophone is studied. Based on data analysis for the parameters measured in high precision, their responses to temperature are revealed, including the output resistance, natural frequency, damping and sensitivity. Some strategies are proposed for controlling the variations with respect to temperature and the feasibility is shown by the preliminary experiment results. At last, it is shown that the parameters of a geophone can be controlled, and without a further significant improvement, a supper-geophone with high precision can be made working in a range of 10-20Hz.
