Crankshaft Sensor for Fiat CINQUECENTO 46417650
The abs sensor is applied to the ABS (Anti-lock Braking System) of the motor vehicle. In the ABS system, the speed of the vehicle is mostly monitored by an inductive sensor. The abs sensor outputs a set of standards through the action of the ring gear rotating synchronously with the wheel. Sinusoidal AC signal whose frequency and amplitude are related to wheel speed. The output signal is transmitted to the ABS electronic control unit (ECU) for real-time monitoring of the wheel speed.

Diversity and rapid variability of the measured object
Types of sensors commonly used in automobiles include wheel speed sensors, crankshaft/camshaft position sensors, temperature sensors, pressure sensors, knock sensors, and the like. For the endless models, 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 the traditional single test bench unable to balance such diverse Sensor production.
In actual production, the test content of different sensors has a certain approximation. Because from the test principle, automotive sensors are mainly divided into active/passive, temperature, pressure sensors and other types. In other words, for different sensors, as long as the test principle is the same, it means that their test instruments and other equipment are the same.
Automotive sensor production lines require economical, efficient, automatic, and flexible test equipment, and must be characterized by high automation, high efficiency, high productivity, and high reliability. Sensor manufacturers hope that after a one-time investment, the test equipment itself can be continuously expanded to effectively support the latest products and higher performance index requirements, thus ensuring the effectiveness of equipment capital investment.
In order to ensure the quality of production, equipment needs to have a certain statistical ability of production processes, and help to reduce the quality of production caused by human factors. Integration and intelligence are the development trend of automotive sensors. If only the final test is performed, 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, and on the other hand, information and data sharing between the devices can be realized.
