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
- 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.
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.
