Pressure sensor usually consists of a pressure sensor and a signal processing unit for measuring the pressure of liquids and gases.
According to different test pressure types, pressure sensors can be divided into gauge pressure sensors, differential pressure sensors and absolute pressure sensors. According to the working principle, it can be divided into Ceramic Pressure Sensor, diffusion silicon pressure sensor, piezoresistive pressure sensor, sapphire pressure sensor and so on.

The domestic cold-rolled coil market was slightly higher, and the transaction was slightly improved. Analysts say that the recent strong earthquake in Japan may have a certain impact on the production of Japanese steel mills such as Nippon Steel.
According to the data, in 2010, China imported more than 1.43 million tons of cold-rolled coils directly from Japan. After a strong earthquake, the imported Japanese steel has a certain gap, and downstream users may find alternative resources in China.
Earthquake affects steel exports, domestic steel prices are expected to stop falling for a short time
According to Xinhua News Agency, due to the strong earthquake in Japan, some merchants have improved their expectations for steel exports in the later period. Coupled with the continuous rise in steel forward prices, the spot steel market offers have risen.
