STUDY OF AN INCLINOMETER FOR MEASURING THE ROTATION OF SECTIONS DURING STRUCTURAL TESTS

ETUDE D'UN CLINOMETRE ADAPTE A LA MESURE DES ROTATIONS DES SECTIONS LORS DES ESSAIS DE STRUCTURES

The measurement of the rotation of sections in tests on prestressed and reinforced concrete structures gives rise to complex problems because of the magnitude of the measurements to be taken and of the high degree of accuracy required. To solve these problems, an inclinometer was designed based on the well known pendulum principle. The pendulum, articulated without friction thanks to a very flexible steel blade, transmits its movement, without play or friction, to a linear sensor with inductance variation. The device which is simple to design and produce, gives very satisfactory results: maximum sensitivity of + or - 0.5/100000 rd; range of measurements of + or - 5/100 rd; continuous and high output tension proportional to the rotation facilitating direct recording. /TRRL/
