Application of film pressure sensor in intelligent vehicle

Auguest 3rd, 2017 , Posted By H. Rackham

Tire pressure detection: the tire pressure test system based on membrane pressure sensor is a general tool for tire industry, which can obtain the tire imprint pressure distribution of passenger cars, trucks, off-road vehicles, agricultural vehicles and aircraft tires. Dynamic or static imprinting is also easy to obtain. It can display the distribution of tire contact pressure with high-throughput color pictures. The system has a very intuitive and professional image analysis software, which can carry out qualitative and quantitative analysis on the acquired images.

The system can quickly measure the contact area, edge area, tread length and width, and the pressure distribution of the section of the tire. Then it is very convenient to compare the characteristics of a variety of tires, or to compare the characteristics of a tire under different loading and inflation conditions. This information helps designers and manufacturers analyze the composition and tread design of different tires, conduct quality control measurements, develop reference standards, and assess the impact of vehicle suspension. It can be directly placed on the road, car repair shop, tire roller or fixed on the running plate testing machine, or even buried under the road to measure the pressure of the car when driving through the soil.
