Product Details
4.5hz Geophone Seismic Sensor Moving Coil Geophone 375 Ohm
Introduction
The 4.5hz Geophone Seismic Sensor (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.
