Fuel common rail pressure sensor 55PP32-01 for Santana

Test characteristics

The diversity and rapid change of the tested objects

The commonly used sensor types in automobiles include wheel speed sensor, crankshaft/camshaft position sensor, temperature sensor, pressure sensor, knock sensor and so on. In view of the endless stream of vehicles, each sensor with the same function has various differences in appearance, and the requirements of measurement indicators and production environment are becoming more and more demanding, which makes it impossible for the traditional single test bench to take care of such a variety of sensor production.

Test approximation

In actual production, the test contents of different sensors are similar to some extent. Because from the test principle, automobile sensors are mainly divided into active/passive, temperature, pressure sensors and other types. That is to say, for different sensors, as long as the test principle is the same, it means that their test instruments and other equipment are the same.

Testing equipment

The automobile sensor production line requires the use of economical, efficient, automatic and flexible testing equipment, and has the characteristics of high automation, high efficiency, high productivity and high reliability. Sensor manufacturers hope that after one-time investment, the test equipment itself can be continuously expanded to effectively support the latest products and higher performance requirements, thus ensuring the effectiveness of equipment capital investment.

Other requirements

In order to ensure the production quality, the equipment needs to have a certain statistical ability of production process, and it is helpful to reduce the problem of production quality reduction caused by human factors. Integration and intelligence are the development trends of automobile sensors. If only the final test is carried out, it is too late to find the problem, so the test will often interact with the production process. In this way, on the one hand, the test equipment is required to be well connected with other equipment on the production line, on the other hand, the information and data sharing between the equipment can be realized.
