GeoCloud Laser Distance Meter

GeoCloud laser distance meters provide automated distance measurements to monitor potential movement of remote structures. These sensors are also called laser extensometers or optical displacement sensors. Datasheet

GeoCloud Laser Distance Meter

Applications

  • Monitoring pillars, bridge decks, retaining walls, tunnel profiles for deformation or movement.
  • Monitoring heave or settlement of floor slabs (changes in ceiling-floor distances).
  • Monitoring structural movements at locations that are difficult or dangerous to access.
  • Monitoring change in inclination using the built-in 3-axis tiltmeter.

Advantages

Remote measurements: The laser distance meter works with natural surfaces up to 165 feet away and with targets up to 500 feet away.

Built-in Tiltmeter: A built-in tiltmeter provides high resolution tilt measurements.

Easy Installation: The module is compact, easy to install, and requires almost no maintenance.

Cable-Free: GeoCloud sensors provide their own power and transmit measurements by radio, entirely eliminating the cost of cables, cable protection, and cable maintenance.

GeoCloud Services: GeoCloud provides access to data wherever there is an internet connection. GeoCloud services operate 24 hours a day, processing measurements, checking for alarms, and generating graphs, reports, and alerts.
