2hz/2.5hz/4hz/4.5hz Geophone Seismic Sensor for Sale
It are remarkably simple (yet ingenious) devices. The active element of the device consists of a mass hanging on a spring. When the ground moves, the mass (because it has inertia) wants to remain motionless. If you were watching the seismometer as the ground moved, it would look like the mass itself was moving. But, in reality, you are moving with the ground, and the mass is remaining motionless.
