Guralp 3/5TB
Achieve exceptional dynamic range with the dual-sensor 3T/5T borehole package.
This solution enables both acceleration and velocity measurements within a single borehole instrument and is designed for seismic monitoring applications requiring a wide dynamic range.
Product Brochure
- Provides a total effective dynamic range exceeding 200 dB with an extremely low noise level
- Enables simultaneous monitoring of weak signals and strong ground motions within the same system
- Features a single-arm borehole locking mechanism for borehole diameters ranging from 99 to 203 mm, or can be used with sand backfill to reduce convection
- Operates with a tilt tolerance of up to 2.5°, optionally extendable to 12.5°
- Offers a waterproof and robust design thanks to O-ring seals used throughout the structure
- Provides an optional integrated inclinometer for position control at depth
- Available with pass-through cable borehole locking units, allowing installation in already instrumented boreholes
- A strain-relief mechanism fully isolates the sensors from movements in the suspension cable
