New - Digital bubble level for alignment and leveling

Now it's even easier to deploy your direct bury seismometers

If you are installing a direct burial sensor at depth with an alignment rod, this feature makes it possible to use a 'virtual bubble level' to align and level your sensor when a the sensor is out of visual range.

 

The bubble level visualizes the tilt of the seismometer in near real-time (approximately 1 second delay). It can take the place of a physical bubble level in posthole installations where the seismometer may be out of sight of the installer, or too dark or dirty to see clearly.  It also eliminates the need to carry a separate level bubble accessory for posthole seismometers.  For deeper posthole installations (beyond arm’s reach), the seismometer may be manipulated with an alignment rod while watching the bubble level GUI.

 

 

Virtual bubble level on Centaur graphic user interface

 

When the display screen is oriented in the same direction as the seismometer, the digital bubble level mimics the behaviour of a real bubble level—that is, tilting the seismometer in the north direction causes the bubble to move south, and vice versa. This feedback is useful for orienting the seismometer in a level position.

 

Alternatively, when the display screen is oriented 180° to the seismometer (south on the display screen lined up with the north mark on the seismometer), the digital bubble level behaves like a cursor controlled by a joystick—that is, tilting the seismometer in the north direction causes the cursor to move north on the screen.  Some users may find this behavior more intuitive, allowing them to level the seismometer more quickly.

 

Centaur technology is also integrated into our Meridian Compact and Meridian Compact Posthole digital seismographs.
