HSSG Hydrostatic level sensor
Measures vertical displacement and structural settlement from changes in liquid levels in connected vessels. Suitable for foundations, hydraulic structures, and geotechnical monitoring.
Application and connection
Measuring vessels are connected by a hydrostatic line. When parts of a structure move vertically, the liquid levels change; the system determines settlement from this difference.
Used to monitor foundations, piles, hydraulic structures, and buildings near tunnels. Data is collected over RS-485; wireless transmission requires separate acquisition modules.
