4.5Hz Geophone Element (S10045) What is it? What is it used for? What are its features? Description: The 4.5Hz Geophone Element (S10045) is a low-frequency seismic sensor used to detect ground motion and convert it into electrical signals. With high sensitivity and a low natural frequency, it is particularly suited for deep subsurface exploration. Purpose of Use: Detects low-frequency ground motion and surface waves Ideal for seismic reflection and refraction surveys targeting deeper geological layers Works in conjunction with seismic acquisition systems in the field
