CMG-3TB
The CMG-3V sensor is identical to the vertical-component module of
the 3TB instrument, allowing you to build mixed arrays of 3V and 3TB
sensors with identical response characteristics.
1.2 Digital borehole installations
The Güralp DM24 digitizer is available in a borehole sonde form.
Connecting a Güralp borehole instrument to a downhole digitizer
allows you to construct a true digital borehole installation. This has
several advantages over a traditional borehole setup:
•
Digital signals are not subject to attenuation as they travel up to
the surface, so signals received are stronger and more reliable.
•
Digitizing the data at source allows you to ensure that its origin
can be reliably traced.
•
The DM24 digitizer may also be combined with an
Authentication Module within the borehole sonde, allowing you
to generate cryptographically-signed data at the point of origin.
