Monitoring Systems / NOVA TB15


Biaxial Inclinometer

Wall tilt-meters are used to monitor changes in the inclination of structures, walls, retaining walls, rock masses and for evaluating the behavior of bridges and beams subject to load.
Equipped with a biaxial MEMS sensor, this instrument detects the angular variations of the structures, providing useful indications about the rotational movements of the same.


  • Particularly suitable for long-term monitoring or load tests;
  • Accuracy and resistance;
  • IP67 protection degree;
  • Vertical and horizontal installation;
  • Ease of assembly;
  • Compatible with the “NB-IoT 5G DATA ACQUISITION SYSTEM” and with the “NOVALog” data acquisition control unit.


  • Monitoring of concrete structures;
  • Load tests on bridges and viaducts;
  • Historical buildings;
  • Containment walls;
  • Monitoring of steel structures;
  • Concrete dams;
  • Wind towers;
  • Land subsidence;
  • Monitoring of landslides.
