Miniature sensors are currently the most successful and practical microelectromechanical devices, which have the characteristics of small size, light weight, good performance, and low cost. It mainly includes miniature pressure sensors and miniature acceleration sensors that use the mechanical deformation of the miniature diaphragm to generate electrical signal output; in addition, there are miniature temperature sensors, magnetic field sensors, gas sensors, etc. The area of these miniature sensors is mostly below 1mm2.Gravity Sensor,Small Range,Micro Electronic Scale,Weight Scale Sensor,Full Bridge Strain Type Electronic Micro Pressure Load Cell Weight scale sensor, full bridge strain type electronic micro pressure load cell, gravity sensor, load cell, micro electronic scale, small range Ningbo Santwell Imp & Exp Co.,Ltd , https://www.santwell.com
Among the 119 major products counted this month, there were 104 products with a cumulative year-on-year increase, accounting for 87.39% of all reported product varieties; 96 products with double-digit growth, accounting for 80.67% of all reported products; The output of these products decreased compared with last year, accounting for 11.76% of the reported products. The specific product completion is as follows:
First, the production and sales of most agricultural machinery products are booming. The output of medium-sized tractors, on-site tractors, grain processing machinery and cotton processing machinery has increased by more than 30%. The output of grain processing machinery has increased significantly compared with the same period of last year, from January to March. The increase was 93.24%.
Second, the output of metal cutting machine tools and metal forming machine tools kept growing at the same time. Among them, CNC metal cutting machine tools and CNC metal forming machine tools grew rapidly, up 60.43% and 32.68% respectively. In addition, the numerical control system equipment increased rapidly from January to March, more than doubled.
Third, in the first quarter, China produced a total of 4.588 million vehicles, a year-on-year increase of 73.23%, and basic passenger vehicles increased by 79.19% year-on-year. Among them, cars with a displacement between 1.6 and 2.0 liters grew faster, accumulating a year-on-year increase of 108.49%. The speed is higher than the displacement of 1 to 1.6 liters. At the same time, the growth of cars with displacements of 2.5 to 3.0 liters is also relatively fast, with a cumulative increase of 164.73% year-on-year. The growth rate is higher than that of cars with displacements of 2.0 to 2.5 liters, mainly due to the low base last year. Cargo and road passenger cars increased by 53.70% and 46.45% respectively.
Fourth, heavy mining machinery products such as conveying machinery, cranes and mining special equipment have grown rapidly, and the growth rate is above 20%. Metal rolling equipment, which has been growing at a low rate since last year, fell 6.77% year-on-year from January to March this year.
Fifth, optical instruments and automotive instrumentation in the instrumentation industry grew rapidly, up 61.05% and 105.04% respectively. However, electrical instrumentation, analytical instruments and devices continued to decline in output last year, with a year-on-year decline of 2.73% and 9.34%, respectively.
Sixth, the steam turbine generators in power generation equipment grew at a low speed, up 5.62% year-on-year. Wind turbines grew rapidly, up 30.33% year-on-year. The output of hydroelectric generating units decreased by 7.29% year-on-year. In addition, the fast-growing products in the electrical industry include: power station turbines, low-voltage switchboards, optical cables, steel strands and industrial electric furnaces, which grew by more than 30% year-on-year.
From January to March, the production and sales rate of machinery products increased slightly year-on-year. The production and sales rate of machinery products in the whole industry was 97.38%, 0.77 percentage points higher than the previous year (96.61%); at the same time, it was slightly lower than the national industrial product sales rate (97.5%) 0.12 percentage point.
