Güralp 5 series-5TB
5T Borehole

A low noise, triaxial force feedback borehole instrument.
The Güralp 5T borehole is equivalent to the 5T vault accelerometer, designed for strong-motion borehole studies. Analogue borehole instruments can be combined with DM24 borehole digitizers and DCM/AM borehole data modules to build a fully networked, authenticating digital instrument inside a single borehole. If a downhole digitiser is not required the instrument is supplied with a strain relief mechanism to isolate the sensors from motions in the load bearing cable.
