This market concerns the instrumentation of the Pont-canal located at the level of the village of Houdeng.

As the frequency of manual measurements does not allow sufficiently regular monitoring of the bridge, it was decided to place instrumentation which will allow:

- performing four settlement measurements per day at the level of the supports or at the level of the deck, vertically above the supports (32 measurement points);

- carrying out four temperature measurements (two in concrete and two in air) per day;

- their transmission, once a day, by telemetry.

The various components of the system are chosen so as to allow it to operate for 20 years.

Design and installation of an instrumentation that will:

- performing four settlement measurements per day at the level of the supports or at the level of the deck, vertically above the supports (32 measurement points);

- carrying out four temperature measurements (two in concrete and two in air) per day;

- their transmission, once a day, by telemetry.
