11. Frequently asked questions
11.1 How do I calculate the distance from the
sensor to the measuring area on the road?
Figure 11-1. Right triangle
Where:
c = distance from the head of the sensor to the measuring area on the road
b
= distance from the measuring area on the road to the base below the head of the sensor
a
= distance from the base below the head of the sensor to the head of the sensor
α = measuring angle
1. Measure the distances
a
and
b
.
2. Calculate
c
using the following equation:
3. See Technical specifications (p. 4) for Measurement range requirements.
