Güralp 40 series-40T
Güralp 40T
BROADBAND SEISMOMETER

A rugged and robust threecomponent broadband seismometer. 
The Güralp 40T is ideally suited for installation in vaults with moderate noise. It’s high-gain feedback loop eliminates mechanical non-linearity (the overall measured linearity exceeds 90 dB) and minimizes resonances in the spring system. The 40T’s design has carefully avoided low-frequency vibration modes. The lowest spurious vibration mode of the 40T is a barely measureable resonance at 440 Hz.
