The products are mainly used in data acquisition, signal transmission and conversion, PLC, DCS and other industrial measurement and control systems in the fields of machinery, electricity, telecommunications, electric power, petroleum, chemical industry, iron and steel, sewage treatment, building construction and so on. They are used to improve and supplement the system analog I / O plug-in function and increase the applicability of the system and the reliability of the on-site environment.
YOKOGAWA(橫河)1975年率先研制出世界上*套具有劃時(shí)代意義的集散型控制系統(tǒng)(DCS系統(tǒng)),對(duì)石油、化工等大型工廠的生產(chǎn)過(guò)程進(jìn)行測(cè)量、運(yùn)行監(jiān)視和控制,為工業(yè)的發(fā)展和社會(huì)的進(jìn)步做出了極大貢獻(xiàn),到目前已相繼推出了7代CENTUM DCS系列產(chǎn)品,流量表、變送器、分析儀等現(xiàn)場(chǎng)儀表也得到了用戶的高度評(píng)價(jià)。
YOKOGAWA的計(jì)測(cè)技術(shù)事業(yè)核心--測(cè)量?jī)x器事業(yè),有著高穩(wěn)定性和高可靠性的產(chǎn)品以及始終*于時(shí)代的計(jì)測(cè)技術(shù),使之成為一個(gè)在世界上值得信賴(lài)的合作伙伴。通過(guò)與安藤電氣公司的合并,進(jìn)一步擴(kuò)大了通信測(cè)量?jī)x器的生產(chǎn)領(lǐng)域。如今又將目光投向光通信,移動(dòng)通信測(cè)試和數(shù)字式信息家電等領(lǐng)域,力爭(zhēng)在測(cè)量?jī)x器方面成為*的生產(chǎn)廠家。
