What is a profileometer?
Profilometer is a device used to measure surface roughness. There are two classes of profiles: contact and non -contact. Most of these devices measure the vertical difference between the high and low point of the surface in nanometers. This tight measurement easily illustrates the difference in objects that look or feel equally free of direct measurement. While the profileometer is common in many areas, one of their main uses is to measure the roughness of the road surfaces. The stylus with a diamond tip is triggered through the material sample. The stylus records Groves as a wave pattern and sends the information back to the computer. This computer can use a wool to model the surface as it moves. Before the process is done, the system will have the exact model of each measured location.
These were the first types of profiles and are still very common. Many have advantages over non -contact tools, but are limited to samples. In general, it is difficult to use in the field, because the surveyed surface must be useful under the reading needle.
Non -contact profilometer uses rays of light to read the surface. Like the common range, it shoots the beam and measure the time it takes to return. This provides two main advantages of this Profiliometer style over the contact version. At first it works easily in the field, because it can only sit on the surface and suffer almost no wear, because none of its parts does not touch anything.
This style of Profilometer has one main disadvantage. As it sends data to the central system using digital code, the surface modeling for the area of usable humans should be converted. This requires the next step that the contact version does not need and can significantly extend the modeling time.
One of the areas where the profileometers are very common is measurement of the roughness of the road. For this purpose, the profileometer, together with several other measurement tools, connects to the moving test system. YouThis system can be anything from a standard car to a specialized dolly that only moves the tools. Because these profileometers are used in a distance field, they are always non -contact devices.
The aim of these road tests is to find the roughness of the road section. The results will help determine whether the road needs repair or revival. It also helps to determine the information for tires and driving systems, ensuring that the car provides maximum power and adhesion in different road conditions.
