Installation in a Cut

MagSense installation cut

Installation of the magnetic field sensors in a cut in asphalt and concrete

Both for single-space acquisition and free-flow traffic counts, sensor installation in a grouted cut is possible.

The following pictures illustrate the steps to be taken when installing MagSense® sensors. In the below example, the sensors are used to detect free-flow traffic. Similarly, the magnetic field sensors can be installed in parking lots to detect individual vacant spaces.

Marking

The position of MagSense®– magnetic field sensors is marked precisely.

Cutter

As for the installation of induction loops, too, a conventional saw is used to cut the asphalt.

Cutting depth

The depth of the cut is 6 to 8 cm.

MagSense installation cut

Cutting width

The width of the cut is about 20 mm.

Quartz sand

Then the cut is filled with a layer of 1 to 2 cm of quartz sand.

Sensor insertation

The sensor is inserted and embedded in the quartz sand.

Sensor position

The rotation of the sensor does not matter.

PE-cord

To protect the sensor a 20-mm-thick PE-cord is introduced.

Sealing compound

The casting material can be either hot or cold sealing compound.

Grouting

Over its whole length the cut is now filled with sealing compound.

Scraper

Finally protruding grout is scraped off.

Cleaning

Excess grout and sand are removed.
