Brief introduction of strain sensor classification and application

The global market for strain sensors in 2012 was 6.54 billion yuan, down 5.1% from 2011, mainly due to the decline in global manufacturing demand and the weak growth of the European Union and other economies caused by the European debt crisis. With the gradual recovery of the economy, the backlog of demand in the downstream industry has emerged, and the growth rate of global strain sensor will return to the right track.

Affected by the market downturn in 2012, the overall strain sensor market did not show significant growth in 2013, basically the same as 2012. Under the environment of poor market, domestic sensors will continue to grow due to their price advantage, and the market position of larger manufacturers such as Ningbo Keli and China Aviation Electronics will be further consolidated.

According to R & D strength, technical level and production scale, global strain sensor manufacturers can be roughly divided into three echelons:

The first echelon is dominated by multinational companies, such as Vishay Survey Group, HBM, METTLER TOLEDO and Flintec of Sweden. Among them, Vishay Measurement Group and HBM Company focus on providing one-stop solutions; METTLER TOLEDO Group is good at weighing solutions that open up new fields; Flintec of Sweden is known for its complete products and technological leadership.

The second echelon is dominated by regional leading enterprises represented by CATIC and Ningbo Keli, and each has its own advantages in terms of market segmentation, product prices and downstream applications.

The third echelon is a low-end product manufacturer in China, South Korea and other countries, such as the Bengbu sensor production group. Its products are mainly sold in the country, and its competitiveness is mainly reflected in the relatively low labor cost. Participate in global market competition.

It is worth noting that in the fiercely competitive international sensor market, Ningbo Keli Sensor Technology Co., Ltd. has sprung up to become the only domestic manufacturer that occupies the top five in terms of sales volume and sales volume. In the competition of domestic manufacturers, Ningbo Keli is far ahead of the second-ranked AVIC. Stable market performance has helped Ningbo Keli lead the domestic strain sensor manufacturer for a long time.

The classification of strain sensor is very diverse. According to the material, it can be divided into steel sensor and aluminum sensor. According to the different output signals, it can be divided into digital sensor and analog sensor. According to the shape, it can be divided into bridge. Type, cantilever arm type, etc.

Bridge sensor:

China is the largest production and sales base of bridge sensors, and its production accounts for about 70% of the global total. Ningbo Keli is the largest manufacturer of bridge sensors in China. It has a wide range of products, obvious price advantages, and strong core competitiveness in the market. In 2012, its bridge sensors ranked first in the world in terms of sales and sales volume, and far away Leading the second place.

Steel sensor:

Steel sensors are mainly used in industrial and high-end fields, such as medicine, biology, chemical industry, food and power industries. Due to high safety requirements, huge investment, and high effects, etc., they have high precision and high-speed sensor detection weighing systems. Huge demand.

In the steel sensor market, Ningbo Keli's performance is still eye-catching. It is the only local sensor manufacturer that can compete with foreign manufacturers in terms of sales, and it ranks first in sales volume. As one of the few domestic manufacturers that can steadily produce and supply high-performance stainless steel sensors, Ningbo Keli has a promising market prospect.

Digital sensor:

Compared with foreign countries, China's digital sensors started late. In some core manufacturing processes and advanced technologies, the overall level of China's digital sensors is still far behind that of developed countries abroad. With the maturity of digital sensor technology and the popularization of intelligent digital systems, the proportion of Chinese digital sensors in the world will increase.
