Domestic Trend of Weighing Instruments

The development of modern industrial instrumentation and control not only depends on the level of production technology but also involves engineering application techniques. In recent years, many manufacturers of measurement and control equipment, as well as technology-driven enterprises and engineering companies in fields such as thermal energy, petrochemicals, metallurgy, have made significant advancements in software development and system integration technology. Overseas control systems and products have mastered the application technology for automatic control of large-scale projects and facilities. However, with the emergence of overseas field buses,SOLUTION、MIV、EPCWith the advancement of technology and engineering assembly methods, the difficulty of China's automatic control systems and field instruments entering large-scale projects will increase.

 Our automatic control systems, field instruments, and key precision testing equipment still lag behind international standards.10Please provide the Chinese content to be translated.15The gap in years. China's instrument technology breakthroughs require crossing eight major hurdles.

 Achievement One: Enhanced levels of digitalization, intelligence, and integration

 Modern industrial instruments and meters feature digitalization, intelligence, networking, and integration, yet our country's products are predominantly conventional varieties, with intelligent products only beginning to take off. Taking nuclear power control systems and instrument integration as an example, the gap has widened even more due to weak foundations, as we enter the era of digital control technology.

 Achievement Two: Enhanced Product Reliability

 Modern industrial instruments and meters are characterized by high reliability, performance, and applicability. The distinguishing feature of most Chinese products from foreign ones lies precisely in this aspect. For example, the distribution control systems developed domestically...DCSThe basic performance and functions of electromagnetic flowmeters have approached international standards, but there is still a gap in reliability and engineering application capabilities.

 Breakthrough Three: Enhancing High-Tech

 International Smart Actuators Utilize Variable Frequency Speed Control, New-Type Motors, Low Labor Consumption, and Micro-Piezoelectric CeramicI/PNew technologies such as converters, Bluetooth communication, intelligence, and fieldbus are just beginning to take off domestically.

 Breakthrough Four: Enhanced Product Precision

 For example, with quality flowmeters, the measurement accuracy in foreign countries is categorized as such.4Degree and precision measurable gas0.1Degree, commonly referred to as0.15Domestic production can only reach the level of economy.0，2Rank and applicable types.0.5Another example is the meters at our country's gas stations. . 5%The precision, while overseas30The precision of a万吨 oil tanker for our country is0.1%。

 Breakthrough Five: Rich Variety and Specifications

 With high-precision intelligent pressure/For example, domestic transmitters lack low-pressure differential pressure transmitters.1kPaBelow, high pressure difference800kPaAbove, High Pressure16MPaAbove, certain special requirements in terms of corrosion resistance within the measurement reference range. Not applicable for engineering or system applications.

 Breakthrough Six: Enhanced Automation Level

 For instance, in high-performance photoelectric direct-reading spectrometers, foreign instruments have their vacuum levels monitored in real-time by computers, whereas domestic instruments still require manual operation in many aspects.

 Prosperity Seven: Increase Share of Advanced Products

 Currently, our country has very few, if any, products. For instance, with atomic absorption spectrophotometers, foreign countries have instruments that utilize Zeeman background correction technology, but domestically, such development has yet to be successfully achieved, with advanced demand largely depending on imports.

 Achievement 8: Increased Market Share

 With Programmable Logic ControllersPLCFor instance, currently in China...PLCMarket95%Above, dominated by foreign products. Products from Europe and America are prevalent in medium to large-sized categories.PLCJapan's products excel in the niche sector.PLC领域具有优势，韩国和台湾产品也占有一定的市场份额。中国自主品牌PLCThe company's market influence is minimal, making it difficult to achieve economies of scale. The instrument market is similarly as mentioned earlier.
