Yokogawa Electric Corporation (横河電機株式会社, Yokogawa-denki Kabushiki-kaisha) is a Japanese multinational electrical engineering and software company, with businesses based on its measurement, control, and information technologies.

It has a global workforce of over 19,000 employees, 84 subsidiary and 3 affiliated companies operating in 55 countries.^[3] The company is listed on the Tokyo Stock Exchange and is a constituent of the Nikkei 225 stock index.^[4]

Yokogawa pioneered the development of distributed control systems and introduced its Centum series DCS in 1975.^[5]

Some of Yokogawa's most recognizable products are production control systems, test and measurement instruments, pressure transmitters, flow meters, oxygen analyzers, fieldbus instruments, manufacturing execution systems and advanced process control.

History

Yokogawa traces its roots back to 1915,^[6] when Dr. Tamisuke Yokogawa, a renowned architect, established an electric meter research institute in Shibuya, Tokyo. After pioneering the development and production of electric meters in Japan, this enterprise was incorporated in 1920 as Yokogawa Electric Works Ltd.

In 1933 Yokogawa began the research and manufacture of aircraft instruments and flow, temperature, and pressure controllers. In the years following the war, Yokogawa went public, developed its first electronic recorders, signed a technical assistance agreement for industrial instruments with the U.S. firm Foxboro, and opened its first overseas sales office (New York).

In the 1960s the company made a full-scale entry into the industrial analyzer market and launched the development, manufacturing, and sales of vortex flowmeters, and in the decade following established its first manufacturing plant outside Japan (Singapore), opened a sales office in Europe, and became one of the first companies to bring a distributed process control system to market. In 1983 Yokogawa merged with Hokushin Electric Works and, towards the end of the decade, entered the high-frequency measuring instrument business. In the 1990s, Yokogawa established an office in Bahrain to oversee its business in the Middle East and entered the confocal scanner and biotechnology businesses.

In 2002 the firm continued its growth with the acquisition of Ando Electric, and in 2005 set the stage for a new level of globalization in its industrial automation business with the establishment of Yokogawa Electric International in Singapore. In 2008 the company entered the drug discovery support market with a new bio test system.^[7]

In April 2020, Yokogawa acquired Scarborough-based Fluid Imaging Technologies. Terms of the deal were not disclosed.^[8]

In 2021, Yokogawa focused on cloud-based solutions and industrial IoT applications. The company launched the OpreX Control Care cloud service and acquired Industrial Control Systems, Inc. (ICSI) to strengthen its industrial cybersecurity offerings.^[9]^[10]
