The global sensor market in 2010 will surge – instrumentation, sensors – mechanical industries
Global Sensor Market is showing rapid growth. According to market reports show that in 2008 the global sensor market volume was 50.6 billion U.S. dollars, the global sensor market in 2010 is expected to reach 600 billion U.S. dollars. Eastern Europe, Asia Pacific and Canada to become the fastest growing area sensor market, while the United States, Germany, Japan remains the largest country in the distribution sensor market. Worldwide, the fastest growing sensor market is still on the car market.
"No sensors there is no modern car" has become the industry consensus, which means that the more advanced automotive technology, the higher degree of automation, the greater the dependence on the sensor. In response, industry experts believe that the future will be birth of new automotive applications, with supporting new vehicle sensors. Most important feature of the sensor is constantly introducing new technologies to develop new features, the total development of future automotive sensor technology trend is miniaturization, multi-functional and intelligent.
World development trend of vehicle sensor
Information, an ordinary family car are about to install dozens of sensors, sensors on the number of luxury cars up to 200 only. According to market research StrategyAnalytics expects automotive sensor 2012 Pin Sales amounted to 15.8 billion U.S. dollars.
Vehicle sensors can be divided into three categories: power systems, safety management systems and vehicle comfort systems sensors. Power system in which the largest proportion of sensor market, embodies the most advanced automotive sensor technology. For example, the accelerator pedal position sensor angle error must be less than 0.4%; throttle position sensor requires high reliability, and to be able to work -50 degrees to 150 degrees.
In the power system, lead the development trend of active sensors. Cam and crank sensor because the car's "heart" Engine Closely related to a dynamic system of relations Key . The active cam sensor and crank sensor power systems can provide more protection, they will lead the future development trend. Expected in 2009, there will be 58.2 million active crankshaft sensor in use, and passive sensors will be reduced to 21.5 million.
In safety management systems, pressure sensors achieve airbag. Automotive safety management system is also widely used sensors in the field. The control of a vehicle side airbags Accelerometer And pressure sensors are two options. Authoritative data show that compared with the acceleration sensors, pressure sensors in the side impact test speed, the acceleration sensor faster than almost 3 times, even a small probability of malfunction.
In body comfort systems, doors, transmission, make cars more intelligent passive safety. Door modules, door handles, window controls on the use of a DC motor position sensors, door modules using a distributed architecture, and connected via LIN bus. Transmission through the use of 2-axis or 3 axis angle / linear sensor, gearbox position to meet the different requirements and save costs, the specific choice of sensors will have to function under the car and gearbox design requirements to decide. Passive safety devices including seat load testing, seat belt open / withhold monitoring, seat position adjustment of the test (to ensure effective protection airbag system), etc., which control the details of the demand for automotive sensors is also very impressive.
Acceleration, vibration, speed sensor is a measurement of vehicle movement in the three main sensor, has remained steady and strong growth momentum. Currently, the three sensors produce more than 30 large enterprises, including the top 5 companies account for 31.3% of the market. Such as Endevco accounted 13.6%, WilcoxaResearch 9.1%, Motorola accounted for 4.2%, IMI accounted for 3.0%, AnalogDevices 1.4%.
Emission regulations in Western developed countries, increasingly stringent exhaust emissions requirements, and promote the automotive oxygen sensor development and production.
Now, we have applied oxygen sensor auto oxygen sensor germanium oxide, titanium dioxide oxygen sensors of several.
