Geotechnical IoT Solutions
The wireless tiltmeter and laser-tilt sensors provide tilt and distance measurement readings directly to the gateway for automated movement detection and reporting. Tiltmeters provide tri-axial readings (tilt in three directions) to a high accuracy, providing precise movement detection for structure health determination and excavation and shoring stability.
The laser-tiltmeter is a 2-in-1 laser distance meter and tiltmeter. The laser measures the relative distance between a pair of reference points. While the tiltmeter provides measurements of changes from the vertical level, either on the ground or relative to structures. It is used to monitoring inclinations, movements, and differential settlement required commonly for excavation stability analysis, tunnel convergence, and building displacement monitoring.
Trimble's line of geotechnical data loggers turns any geotechnical sensor into a wireless device. Transform manual and sporadic data collection to regular and automated intervals for a cost-effective way to capture monitoring data. Trimble's line of data loggers includes digital, analog, and vibrating wire systems to support any type of geotechnical sensor you have on site.
- Low-power, long battery life, up to 10 years
- A high sampling rate of up to 30 seconds
- Transfer data to the gateway from up to 15 km away
- IP67 rated
The rugged Long Range (LoRA) radio and 4G gateway, enables communication with the wireless geotechnical sensors and data loggers to connect the project site with the office through a cellular or local network. Data is transferred seamlessly to Trimble 4D Control for automated reporting, alarming, and analysis.
- Communication range with wireless sensors of up to 15 km
- Integrated internal antenna for GPS, 4G, and LoRa
- Manages up to 50 data message per minute
- External waterproof connectors eliminating the need to open the casing during installation
- Three options for region-dependent frequencies - 863-873 MHz, 902-915 MHz, and 915-928 MHz
The Trimble-branded geotechnical product line, powered by Worldsensing, provides a fully automated wireless monitoring solution that helps minimize field visits and increase on-site safety to obtain manual readouts. The automated measurements generate real-time notifications and automated reporting through the new Trimble® 4D Control™ software (T4D) Geotechnical Edition software. Enabling survey, geotechnical and structural engineers to seamlessly expand their monitoring business opportunities with a comprehensive system that incorporates geospatial and geotechnical data. The Trimble geotechnical portfolio includes:

Wireless sensors such as tiltmeter and laser-tilt are deployed on-site and remotely collect movement data and transmit wirelessly to the central gateway.
The comprehensive set of data loggers, vibrating wire, analog, and digital, connect to any existing geotechnical sensors on site such as piezometers, crackmeters, extensometers, pressure guages, and more, and enable data to be sent wirelessly to the central gateway.
All wireless sensors and data loggers send data to a central gateway over long range radio communication (LoRa) and can be deployed up to 15 km away from the gateway.
From here, the gateway transfers data via an internet connection, either ethernet or cellular, to the Trimble 4D Control database where automated reporting, alarming, and visualization are conducted to detect movement in real-time.

Trimble 4D Control integrates data from geotechnical and geospatial sensors on-site into one platform.
Configure geotechnical sensors, alongside geospatial sensors such as GNSS and total station, to manage monitoring data, apply geodetic corrections, report, visualize and share analysis with other project stakeholders.
Real-time analysis is performed on the movement to detect specific trends through techniques such as inverse velocity and velocity calculations.
Automated reports and alarms are generated and sent to any stakeholders on the project site to ensure transparency and safety on site.
