"[introduction] German e + H (enderhaus) is a family business with more than 10000 employees. Last year, its revenue was 2.1 billion euros, of which industrial pressure sensors contributed 230 million yuan. Small range, low power consumption, reliability and high precision are the foundation of E + H in the pressure sensor Market.
German e + H group, founded in 1956, is a family enterprise with more than 10000 employees. Headquartered in Switzerland, it mainly focuses on the market of measuring instruments and automation equipment in the field of industrial process. Last year, its revenue was 2.1 billion euros, of which industrial pressure sensors contributed 230 million yuan, with small range, low power consumption Reliability and high precision are the foundation of E + H in the pressure sensor market.
E + H group has its own independent sales centers and production centers in 12 countries around the world, mainly producing flow meters, ultrasonic radar probes, liquid level meters, differential pressure transducers, water analysis instruments and temperature instruments, of which 70% of industrial pressure sensors are directly sold to customers and 30% are used for internal operation turnover of enterprises in the north of the group.
Li Jian, regional manager of E + H China
Li Jian, China regional manager of sensors and parts of German e + H group, said: "although the revenue of sensors in our group is not too high, it is very important, first, because it is the core competitiveness of various measuring instruments of the group, second, because their own sensors help to continuously reduce costs, and third, because they can provide better after-sales services to direct customers, Fourth, it can help our group enterprises provide customized development services for customers. Fifth, it can provide OEM production services for customers. "
E + H group only develops industrial pressure sensors, and its core competitiveness is small range, high precision, low power consumption and reliability. Li Jian said: "in order to follow China's market goals of 2025 intelligent manufacturing, industrial 4.0 and 5g big data, we have also developed digital output pressure sensors, pressure sensors integrating digital, analog and switching functions, and industrial pressure sensors with digital temperature compensation."
Local instrument manufacturers in China are the largest customer group of E + H group, accounting for 60% of China's total revenue, and 40% serve customized development businesses in various laboratories, universities, aerospace research institutes and some special industries, including some special applications in military ships.
Li Jian said: "compared with other pressure sensor suppliers such as Honeywell, e + H's industrial pressure sensors are mainly aimed at industrial fluid transmitters, flow meters and other markets, while Honeywell should be biased towards the medical market, or the market of water health and air quality. Low power consumption and small range are the core competitiveness of our pressure sensors. Today, we have entered the IOT era. Terminal devices must often transmit data to the cloud. Therefore, low power performance is very important, which is the biggest highlight of our products. At present, there is still a small gap between the measuring instruments of most Chinese enterprises and overseas products in terms of small range and small range, but they will catch up soon. We will seize this opportunity to develop. "
In addition, he said that the e + H pressure sensor also realizes digital output and comes with temperature and pressure compensation, which is also one of our biggest competitive advantages. There is also high-precision measurement. Compared with ultrasonic flowmeter, our detection accuracy can be two orders of magnitude higher.
"After additional pressure and temperature compensation, the monocrystalline silicon pressure sensor can achieve an accuracy level of 2.5 per 10000," Li Jian said. The accuracy of the sensor is generally one thousandth of the level, which is very high. After conditioning circuit and temperature compensation, it can be between 7.5 and 2.5 per 10000, depending on the number of compensated pressure and temperature points. "
In the field of intelligent manufacturing and river water level monitoring, e + H industrial pressure sensor has great advantages. For example, e + H pressure sensors are mostly used for the flow control of food and beverage. Some underground and field water level monitoring and measurement in China, as well as the water level monitoring of river and marine ships, are realized by the industrial pressure sensors of E + H group. These are all due to the long-term stability and high precision of E + H pressure sensors. Other applications include foundation settlement detection, pipeline settlement detection and benchmark instrument of rail transit. This ceramic capacitive pressure sensor with high long-term stability is adopted.
In the medical market, Li Jian said: "at present, our industrial pressure sensors are used in hemodialysis analyzers, because we can provide excellent small range characteristics and high long-term stability. At present, 300000 pressure sensors are used a year, because this pressure sensor is pollution-free and has no oil filling, and can be directly contacted with human blood for recycling."
In 2016, e + H group also launched monocrystalline silicon differential pressure sensor, which is of great concern to the Chinese market. At present, 6-7 sensor suppliers have also launched this product in the market.
Li Jian said: "compared with the traditional silicon capacitance pressure sensor, the monocrystalline silicon differential pressure sensor has three advantages: first, long-term stability, but large range, and third, high overload. At present, the unilateral overload of monocrystalline silicon differential pressure sensor can reach 420 kg, and the bilateral overload can reach 630 kg. "
E + H also has mature supporting products in the traditional oil and gas industry and chemical industry, that is, pressure transmitter, which can also be called intelligent sensing unit. Li Jian said: "our industrial pressure sensors have successfully served the development of national oil field projects, especially the multi parameter remote transmission flowmeter developed in cooperation with key customers in the west, which can better serve China's oil and gas industry. For example, Changqing Oilfield also includes Yanchang oil. "
E + H group can also provide customized sensor development services. Li Jian said: "we can provide customers with core sensor chips and surrounding conditioning circuits. Customers can match their own designed mechanical shell and brand, and entrust domestic local manufacturers to do some specific customized development. In this way, we can achieve rapid market response, and the delivery time is much faster than that of our European enterprises. We also have this semi encapsulated factory in Suzhou, involving flow, temperature, pressure and wastewater analysis. "
In terms of cost, compared with traditional sensor products in China, e + H pressure sensor is about 2.5 times higher. So what's the difference? Li Jian said: "the history of German enterprises and the accumulation process of technology determine the differentiation advantages of overseas products. However, domestic sensor enterprises are catching up. It is estimated that in two or three years or four or five years, this gap will gradually narrow. "
The sensor business of E + H group in China has grown at a compound growth rate of 17% on average in recent years. Li Jian said: "China's market capacity and economic growth rate determine that the future of the sensor business must be in China. We should be able to achieve a revenue of 2.5 million euros this year. ", Read the full text, technical section
