IRS21 Lufft Intelligent Road Surface Sensor
3. Installation
FIGURE 3-1. Core cut for the road sensor.
Hole diameter = 6”
Hole depth = 3”
Saw cut depth = 2”
Saw cut width = 1/2”
Locate the place in the pavement for the sensor. Drill the sensor hole 3” deep,
and clear the drilled hole of all excess material.
Saw cut the road surface for the sensor lead. The cut needs to be extended
beyond the sensor hole to completely clear the sensor hole of excess material.
