General Descriptions

FSS-3M Seismometers are 3-component integrated, electro-magnetic transduction and force balanced electronic feedback Short-period  Seismometer with high sensitivity and large dynamic range.

FSS-3M Seismometers use a short-period mechanical sensor which has stable mechanical resonant frequency and a high-sensitivity electro-magnetic transducer. Its equivalent closed loop resonant frequency reaches 2 Hz and its observation frequency range reaches 260 Hz after using the electronic feedback technology. As a result, the dynamic range of the Seismometer is heightened and the nonlinear distortion is reduced.

FSS-3M Seismometers are simple in structure. The electronic feedback circuit and DC transduction circuit are in the same PC Board which is installed in the sealed metal case together with the mechanical sensor, which makes the performance stable and the maintenance easy.
