pressure geophone

Completely different from the conventional magnetic-electric geophone,piezoelectric ceramic geophone is a kind of acceleration geophone with high sensitivity and simple structure and is widely used in rivers,lakes,oceans and other regions for geophysical exploration.

压电检波器具有灵敏度高、结构简单的特点,广泛应用于江、河、湖泊、海洋等地域的地球物理勘探。
