Monitoring structures on permafrost
Monitoring the temperature and condition of ground foundations and structures.
Discuss your facility
What we monitor
- Frozen ground temperature
- Differential settlement
- Structural tilt and displacement
From on-site measurements to information for staff
Parameters and instrument selection depend on the structure, operating conditions, and existing systems.
On-site monitoring
We select measurement points and instruments for the changes being monitored.
Collection and transmission
We connect measurements to the shared system using the available communication and infrastructure.
Monitoring and events
We set up archives, change visualization, and alerts for responsible staff.
Purpose
Monitoring buildings on permafrost helps track the temperature of the supporting ground and the related structural changes. The data supports early detection of differential settlement and movement of load-bearing elements.
Monitored parameters
- Permafrost temperature beneath the building
- Differential foundation settlement
- Tilt of structural elements
Monitored assets
- Buildings and structures on permafrost
- Foundations and pile supports
- Ground beneath and around the structure
Possible system components
The following families and instruments are examples. The final selection is defined by the project.
Settlement sensorsHSSG Hydrostatic level sensorMeasures vertical displacement and structural settlement from changes in liquid levels in connected vessels. Suitable for foundations, hydraulic structures, and geotechnical monitoring.
Settlement sensorsLNGG Displacement sensorMonitors movement along two or three coordinates. The measurement system includes a laser emitter, target, and electronic unit.
Soil moisture sensorsHMGG Soil moisture and temperature sensorMeasures soil moisture and temperature. Supports calibration for different soil types and using a sample from the site.
Temperature sensors and stringsTHLG-D00 1-Wire thermistor stringMeasures temperature at multiple points along a cable. The 1-Wire interface connects it to data acquisition equipment.
Temperature sensors and stringsTHLG-D11 RS-485 thermistor stringMeasures the temperature profile of soil or structures at multiple points. Transmits readings over RS-485 / Modbus.
Temperature sensors and stringsThG-D01 Temperature sensorDigital sensor for on-site temperature monitoring. Connects to an RS-485 measurement line and uses a threaded mounting.Let’s discuss your task
