Güralp 5TDE
Introduction
2 Introduction
The Güralp 5TDE accelerometer is a three-axis, strong-motion, force- feedback
accelerometer packaged together with a 24-bit digitiser and a flexible data
acquisition and storage unit, all in a single sealed case. The entire system is
self- contained except for its power supply and GPS receiver, which is used for
time-stamping seismic data.
The 5T system combines low-noise components with a high feedback-loop gain
to provide a linear, precision transducer with a very large dynamic range. In
order to exploit the whole dynamic range, two separate outputs are available,
one with high gain and one with low gain. Normally, the high gain outputs are
set to output a signal 10 times stronger than that from the low gain outputs.
See section 2.1 on page 6 for details.
Full-scale low-gain sensitivity is available from 4.0 g down to 0.1 g. The most
common configuration is for the 5T unit to output 5 V single-ended output for
1 g (≈ 9.81 ms

) input acceleration. The standard frequency pass-band is flat
to acceleration from DC to 100 Hz (although other low pass corners can be
ordered.) A high frequency option provides flat response from DC to 200 Hz.
