From design to measurement in the field
GEO Instrumentation designs and manufactures its own vibrating wire sensors and acquisition systems. Our teams work in France and abroad: diagnosis, technical support, instrument assessment and on-site work.
Engineering office
Design and development of custom sensors and systems
In-house machining
CNC lathe and machining centre to keep manufacturing in hand
Quality
Standards and inspection at every manufacturing stage
Support
Diagnosis, instrument assessment and on-site work
Where every millimetre counts
Nuclear
Instrumentation and monitoring of nuclear plants and facilities
Civil engineering
Dams, bridges, tunnels and major infrastructure
Energy
Hydroelectric structures, energy and industrial facilities
LNG / Industry
Monitoring of industrial plants and LNG terminals
Heritage
Monitoring of historic monuments and sensitive structures
Vibrating wire, dual coil
The frequency of a tensioned wire varies with its tension. Fixed to the structure, it turns every deformation into a measurable frequency that stays stable over time.
The principle in detail
Six measurement families
Vibrating wire sensors
The family everything else follows from.
Pressure sensors
Measurement of pore pressures and total pressures in soils and embankment structures.
Displacement sensors
Crack meters and joint meters, mounted either side of the area to be watched.
Extensometers
Measurement of compression and decompression of the soils beneath a structure.
Temperature sensors
Temperature governs every other measurement: concrete moves, steel expands.
Data acquisition systems
Read the sensors, record, transmit.
Inside the structure
Instrument installed in an inspection gallery, two-axis measurement
Against the steel
Sensors fitted to a ground anchor tie rod
French manufacturing, structures monitored over time
Our teams work in France and abroad and support every installation, from design to measurement.
