Measuring systems
GEODYN
Alignment & structural monitoring systems for critical infrastructures
Purpose & use cases
- Monitor slow drifts or thermal deformation of large installations
- Ensure high-precision alignment during equipment calibration or commissioning
- Track dynamic or long-term movement due to environmental or mechanical influences
- Monitor vertical and lateral positioning of key components over long distances
Architecture & key components
WPS – Wire Positioning System
- Measures 1D (X) or 2D displacement (X/Y) relative to a tensioned reference wire
- Capacitive sensor head with multi-electrode architecture
- Typical range: ±2.5, ±10, ±22, ±30 mm and more on request
- Accuracy: 1 to 10 microns (depending on range)
- Resolution : ±0.1 .. ±0.3 microns
HLS – Hydrostatic Levelling System
- Measures vertical movement using the communicating vessel principle
- Capacitive level sensor, facing the free surface of a liquid as an absolute measurement reference
- Typical range: ±5 to ±100 mm
- Resolution: 0.5 to 2 microns
Signal Conditioning & Acquisition Units
- Analog or digital signal modules
- Real-time data capture, remote control or local display
- Compatible with SCADA and stand-alone setups
Accessories & Integration Kits
- Mounting brackets, tension systems (WPS), tubing (HLS)
- Cable kits, temperature probes, alignment tools
- Commissioning assistance and diagnostics kits
Proven applications
- Particle accelerators (beamline alignment, girder control, tunnel monitoring)
- Civil infrastructures (bridges, dams, tunnels)
- Power generation (nuclear plants, rotating machine bases)
- Large scientific instruments (synchrotrons, detectors)
- Industrial assembly lines requiring sub-millimeter positioning
Key Advantages
