Hexis dual sensor

Hexis

APPLICATIONS

  • Earthquake Early Warning systems
  • Structural Health Monitoring (e.g. dams, industry, buildings)
  • Volcano observatories
  • Networked Arrays
  • Posthole and direct burial
The Fortis accelerometer and the Certis medium-motion seismometer combined in a single instrument for a total realised dynamic range that exceeds 200 dB

Certis Seismometer
Certis’ new sensor technology delivers medium-motion seismic monitoring data with instrument state-of-health, response and calibration data. When partnered with the Minimus digitiser, the Certis can also output to serial and offers a remotely adjustable long-period corner to suit the deployment environment.

Fortis Accelerometer
The Güralp Fortis is a very low-noise, force-feedback accelerometer with a flat response to ground acceleration from DC to 100 Hz and a stable phase response within the passband. The Fortis’ output can be set, remotely, at a wide range of gain options, providing flexibility for all strong motion monitoring applications.

Robust design for downhole deployments
The Hexis is housed in a stainless steel enclosure with a 100 bar/10 MPa waterproof connector and a lifting bail.
Dual sensor for maximum realised dynamic range

  • 120 s to 100 Hz velocity response with remote user selectable long period corner between 1s and 120s
  • DC to 100 Hz acceleration response with remote user selectabel gain options
  • Option to output to analogue with serial
  • Environmentally sealed, stainless steel enclosure with 100 bar/10 MPa waterproof connector
