Approximation test content in the actual production, test content from different sensors also have a certain similarity. Because the test principle, automotive sensors are divided into active / passive, temperature, pressure, and other types of sensors. That is, for different sensor automotive sensors which, as long as the test principle is the same, it means that their test equipment and other equipment is the same. Efficient and flexible production line test equipment automotive sensors require the use of economic, efficient, automated, flexible test equipment automotive sensor production, but also to have a high degree of automation, high efficiency, high performance, high reliability. Disposable sensor manufacturers hope into the future, the test equipment itself can continue to be expanded automotive sensors, effectively support new products and higher performance requirements to ensure the effectiveness of capital equipment investment. Sensor means can feel the physical requirements of automotive sensors offer, according to certain rules to convert the device or devices available input signal. Simply put, the sensor is converted into electricity to non-power devices. Sensor sensitive element usually consists of the conversion element and the measurement circuit of three parts. 1), sensitive components are those that feel the direct (or response) is measured part of the upcoming conversion is measured by a sensor sensitive components have to be measured to determine the relationship of non-electric or other amount. 2), then the non-electricity conversion element is converted into electrical parameters. 3), the effect of the measurement circuit is to convert the electrical parameters of the input element processed into a voltage, current or power frequency can be measured, for display, recording, control and processing section. Mainly electromagnetic induction type, photoelectric, variable reluctance and Hall concentration. Widespread use of electromagnetic induction type speed sensor and Hall on electric vehicles.
