The Internet of Things (IoT) is dramatically changing the business of geotechnical monitoring through the integration of truly smart instruments that integrate sensing elements, signal processing, telemetry with abundant local and cloud-based storage. The consequence is a more user-friendly experience, improved reliability, improved data security and above all, reduced cost. YieldPoint’s digital strategy leverages these opportunities for geotechnical engineers.
Networking and Telemetry
BluGateways are battery powered telemetry devices that fully integrate the functionality of a data-logger and communication gateway. YieldPoint’s latest line of Gateway devices provide centralized data-logging and data upload over Ethernet, WiFi, and Cellular (LTE-M) communication. The system can aggregate instrument readings from (i) BT5 beacons (ii) YP wired RS485 instruments and (iii) VW instruments. Local BT5 clusters of instruments can “beacon” data to a gateway over a range of 100m LoS. All functionality is managed by YieldPoint’s BluPoint Android App.

Our various data-loggers for geotechnical monitoring bring easy and modular capability and effortless scalability to the largest monitoring program. They accept (no configuration required) all instruments in our product-line for rock movement and ground support behavior monitoring. They represent a major step forward compared to analog data-loggers that tend to be expensive, require a cable connection for downloads and are more difficult to configure, often involving expertise to create a proprietary script or program.
YieldPoint data-logging from digital geotechnical instruments solves specific problems such as:
- Inaccuracies related to changes in geotechnical readings with lead-wire length
- Instability due to water ingress affecting analog signals
- Errors related to temperature changes
- Human errors in the application of calibration coefficients
- Errors related to the mapping of instruments to data-logger ports
- Lead-wire vulnerability
Manual readout unit for geotechnical instruments
Manual readings of ground support behaviour data or rock deformation data are important to verify that instruments are operational during installation. They are also useful when a dataset is showing unexpected or irregular readings. YieldPoint has two solutions: the d-Reader and d-Tablet.
d-Reader is a simple, powered instant readout unit that requires zero configuration to operate any of our geotechnical instruments. No button to press: the unit powers the instrument upon simple connection and instanjtly displays battery level, instrument serial ID, instrument type and the apprtopriate readings, all on a loop.
d-Tablet can also be used to download geotechnical data from d-Loggers when a laptop computer would be impractical.
