Click on the quantity：734Today is June 12, 2024 (German time), the third day of the flight from Iceland to Germany. Attend the world's largest Sensor exhibition, the annual "Sensor+Test" in Nuremberg, Germany, to try to understand the general dynamics of sensor development around the world.
Xi'an Chinastar M&C Ltd. has participated in this exhibition for the 16th year, and it is also the earliest and most frequently participated company among Chinese enterprises. Today has been the exhibition for two days, let's talk about the general feeling.
First, due to the impact of the epidemic, the Ukrainian-Russian war, the Arab-Israeli war and other aspects, the number of global companies participating in this year's exhibition should be said to be a new low in my experience of more than 10 years, the number of exhibitors is about 380. In history, the largest number of exhibitors in one year is close to 800, and under normal circumstances, there are about 500. There is only Hall 1 and half of Hall 2, and the conference hall in the exhibition is larger than before.
Second, the number of visitors, on the whole, seems to be much lower than usual. In addition to the global economic downturn, Russia. The number of visitors from Belarus, Ukraine and Israel is certainly much lower than usual, and the second day of the exhibition, which is usually considered to be the largest number of visitors, does not seem to be very large today. In addition, these professional exhibitions in Germany, if there is no invitation, visitors need to pay to buy tickets. This year, it is said that the total cost of a three-day visit is 85 euros, and if it is a one-day visit, it is 40 euros.
Third, Chinese exhibitors hit a record high, reaching nearly 40, accounting for more than 10% of the total number of exhibitors, China Shenzhen Council for the Promotion of International Trade focused on showing Shenzhen sensor companies in a booth, if each company is counted, the number of exhibitors is said to reach about 80. When Xi'an Chinastar M&C Ltd. participated in this exhibition in 2005 as the first and only one in China, Roseman, former chairman of the German sensor Association AMA, once said to me that they invited Chinese enterprises to participate, one this year, two next year, take your time, we are not afraid of slow, I believe there will be more Chinese companies to show to the world in the future. If the old man is still alive, he will be glad.

Fourth, in addition to the commonly used pressure and temperature sensor exhibitors. Optical including laser, infrared microwave sensors and their applications are also significantly increased, gas sensors including traditional semiconductor technology, electrochemical technology, contact combustion principle, many optical gas sensor companies have also demonstrated their latest achievements. Exhibitors also accounted for a considerable proportion. It can also be said that pressure, temperature, gas, optical four categories of sensors occupy the majority. This exhibition process industry used in the pressure, temperature, flow and discrete industry in the photoelectric switch, close to the switch sensor companies, has historically not accounted for the main position, the exhibition more focused on the basic sensor devices.
Fifth, most of the world's famous sensor companies also participated in the exhibition, especially European companies. However, their booth occupies a small area, the decoration grade is not high, TE Connectivity, Honeywell, Sensata, E+H, TDK and so on all participated, but no particularly eye-catching new technology appeared.

Our Xi'an Chinastar M&C Ltd. brought China's original innovative product MCS high-end pressure sensor core, appeared in the overseas exhibition for the first time, attracting the attention of professional visitors. In addition, the wireless Bluetooth technology pressure and temperature sensor exhibited for the first time also attracted great interest from the visiting audience, and there were more customers to discuss samples and tests.
For the MCS pressure sensor core, visitors are concerned about the process method, reliability, stability and cost. The wide operating temperature range (operating temperature -65 ° C ~ +175 ° C) and very high accuracy (0.02%, 0.05%) are important parameters of interest to visitors. Due to the use of metal materials, but not sputtering process, so the temperature coefficient is very high, the best temperature coefficient can reach 5ppm, while the pressure range can be low, the maximum damage pressure can reach 20 times the range.
In addition, the newly developed wireless Bluetooth pressure and temperature sensor, due to its small size, built-in battery, and normal working life can reach 5 to 10 years (depending on the transmission frequency) can be used in many applications. The transmission distance is about 20 meters, in a radius of about 20 meters, if there are multiple (dozens or even hundreds) pressure, temperature measurement points, you can very simply do not use cables, use a DTU can achieve the purpose of measurement.
The last day of the exhibition today, the next episode plans to talk about the Chinese enterprises to participate in the exhibition, welcome interested friends can contact Gu, talk about their feelings.
