GeoCloud Laser Displacement Sensor

GeoCloud laser displacement sensors provide remote, high-precision measurements to monitor movements and deformation. Datasheet

Laser Displacement Sensor

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 displacement measurements: The laser optical displacement sensor (ODS) 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 Laser ODS 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.
