High Sensitivity 4.5Hz Geophone Seismic Sensor Horizontal type

Country/Region	china

Product Details

High Sensitivity 4.5Hz Geophone Seismic Sensor Horizontal Type

The geophone 4.5hz (EG-4.5-II) is a conventional type of moving coil geophone with small
error in working parameters and stable and reliable performance. The structure is reasonable in design, small in size and light in weight, and is suitable for seismic exploration of strata and geological environments of different depths.
It is equivalent to SM-6 B coil 4.5hz geophone.
Widely used in industrial vibration-monitoring systems.
Ideal choice for shear-wave horizontal elements.
