Audited Supplier GD-3C Low Frequency Three-components Geophones
GD-3C is a low-frequency, high-sensitivity geophone model, which does not requiry an external power supply. What it can do is to receive very deep, low frequency and weak signals. It is necessary for seismic surveys and widely used in engineering seismic measurement, single point seismic exploration and other vibration analysis fields.
Features:
* Long travel version, with max coil excursion p-p 6.0mm
* Special orientations upon request beyond normal vertical and horizontal options
* Rugged construction with precious-metal rotating-coil contacts
* 200V·m/s high sensitivity
Functions & Application:
* Engineering seismic measurement
* Single point seismic exploration
* Vibration analysis fields
