Domestic sensor industry is a long way to go. At present, the automation products and abroad there is a big gap, especially in the field of high-end industrial automation sensor, is almost a blank in China, domestic use by more than 90% of high-end sensor mainly from Europe and the United States, Japan and other developed countries technology, and expensive, and the goods time long, or even ban certain products to China sales, military industrial enterprises and high-tech areas such as sales to China.

Industry development, precision is still the important factor. Surface, compared to the sensing accuracy, the market demand for smaller and more multifunctional sensor is greater. Under the condition of the given cost, however, sensing accuracy is still mainly factor should be the manufacturer. Only consider multi-function sacrifice accuracy, will bring adverse consequences.

In order to achieve the high precision, the price of the sensor will improve accordingly. But this is not the economy, also can't meet the needs of low-cost, large-scale application. Engineers should not be because of low-cost sensors not optimal solution is to ignore the accuracy value. This is very important, no matter whether it is "low cost", accuracy has become a differentiation advantage. Low-cost applications can not be ignored the importance of precision of another key lies in the fact that the reserve is easy to install parts is very good. Precision low sensing technology can be completely offset the advantage of using plug and play technology. However, this advantage for engineers to meet the design requirements are of great value.
