G130 Gauge - Measures the change in sag
Made in France

Table of contents


> Detailed description of G130 gauge

With the device depicted, which uses the simplicity and precision of the G1 gauge, the change in sag, the lean of a wall or the distortion of a structure relative to 2 fixed points can be detected to 1/10th of a mm.



  • The body of the G3 gauge is firmly attached to the structure under study, either by a self adhesive tab or if the surface is irregular, damp and of poor quality, using an intermediate plate.

  • The sensor mounted on the G3 gauge arm is in contact with the cold drawn Invar wire stretched between 2 fixed points independant of the structure being monitored.

  • Readings are made under constant tension controlled by a pre-loaded spring.
