Mounting Locations
Two sets of #10-32 socket-head cap screws are included with the sensor. The #10-
32x3/4” screws are suitable for mounting to tubes between 5/8” and 3/4” in diameter.
The #10-32x1-1/4” screws are suitable for mounting to tubes between 15/16” and 1-1/8”
in diameter. The screws are driven with a 5/32” Allen wrench.
The sensor needs to have good clearance from the ground and no parts of the vehicle
should obstruct the sensor’s field of view. The closer to the ground the sensor is the
smaller the sample area is for road temperature.
The sensor can be mounted at less than 1 foot; though it is not recommended as the
sample size will be small. Also snow, ice, salt, and dirt can be thrown up and cover the
distal end of sensor at that height should they be present on the road. Sensor can be
mounted as high as 8 feet.
Figure 1
shows the clearance from the vehicle versus the
height of the sensor above the road surface. It is important to note the higher the sensor
is mounted, the greater distance from the vehicle is needed to ensure the sensor is only
measuring road temperatures, and not a combination of the road and vehicle
temperatures. For every foot of height the width of the area measured widens by
approximately 2.1 inches.
