EJA transmitter measuring principle
EJA transmitter measurement principle:
The EJA transmitter is the latest product introduced by Yokogawa Electric Co., Ltd. in the mid-1990s. It pioneered the use of a true digital sensor--single-crystal silicon resonant sensor. It has created a new era of transmitters with higher accuracy. Stability, reliability, self-promotion to the market, praised by all walks of life. At present, EJA transmitters sold throughout the Chinese market have reached 1 million units. EJA transmitters have replaced Rosemont, E+H, Honeywell, Siemens and other brands to become the first brand in the Chinese market.
EJA transmitter basic information:
The development of the EJA transmitter won the Japan Industrial Society's highest award - the Greater Hanoi Memorial Award and the quality product award presented by Ryutaro Hashimoto, and passed multiple safety certifications in advanced countries such as the United States, the United Kingdom, France, Germany, Russia, and China. . In 1995, Yokogawa Electric Co., Ltd. and Chongqing Chuanyi Plant Co., Ltd. jointly invested 14.2 million U.S. dollars and became Chongqing Yokogawa Instruments Co., Ltd. (CYS). The company now produces and sells 120,000 EJA smart transmitters, and its sales volume continues to grow rapidly. It has become China's largest and most advanced transmitter company. EJA smart transmitter adopts single-crystal silicon resonant sensor technology developed by Yokogawa Electric in Japan. It is the most advanced transmitter in the world. Since entering the Chinese market, it has been favored by the majority of users and is the most popular in the transmitter field. Vibrant branded products. CYS is one of the three largest production bases of Yokogawa EJA smart transmitters in Japan. It combines ISO9000 quality assurance system with Yokogawa's 5M quality management method. It adopts advanced manufacturing technology and high-tech equipment to ensure CYS products. After the same quality of Japanese products was introduced to the market, it was well received by Chinese customers. In May 1997, it obtained the certification of 200MW, 300MW, and 600MW units from China's Ministry of Electric Power and the certification of China's Ministry of Chemical Industry and the petroleum sector.
