　　格拉夫

　　Graeff

　　1930年， Graeff（格拉夫）發明第一支壓力傳感器轉換機構，在此機構中,膜片、彈簧或Bourdon管的移動量變為電量部分,壓力膜片成為電容部分,指示器可動機構成為電位計分支，實現了壓力測控裝置。

　　Graeff 源自歐洲，品牌超過90年的歷史，Graeff專注于溫度傳感器、熔體壓力傳感器、流量傳感器、智能傳感器、位移傳感器、壓力傳感器、液位傳感器、壓力溫度控制儀表、控制單元、控制系統、驅動器、加熱器、激光技術、自動化及物聯網系統的研發；Graeff（格拉夫）是NTX環保型無汞填充高溫熔體壓力傳感器領域的創變者；Graeff（格拉夫）多個系列產品主要用于食品、制藥、生物技術、化工、石油化工能源工業、電站、污水處理、航海造船工業、環境工程、噴涂設備、塑料、化纖、橡膠、制藥、冶金、石油化工、汽車制造、陶瓷玻璃等領域。

　　In 1930, Graeff invented the first pressure sensor conversion mechanism. In this mechanism, the movement of the diaphragm, spring or Bourdon tube becomes the electric part, the pressure diaphragm becomes the capacitor part, and the indicator movable mechanism becomes the potential. The meter branch realizes the pressure measurement and control device.

　　Graeff originates from Europe and has a brand history of more than 90 years. Graeff specializes in temperature sensors, melt pressure sensors, flow sensors, smart sensors, displacement sensors, pressure sensors, liquid level sensors, pressure and temperature control instruments, control units, control systems, Research and development of drives, heaters, laser technology, automation and Internet of Things systems; Graeff is an innovator in the field of NTX environmentally friendly mercury-free high-temperature melt pressure sensors; Graeff's many series of products are mainly used In food, pharmaceutical, biotechnology, chemical, petrochemical energy industry, power station, sewage treatment, marine shipbuilding industry, environmental engineering, spraying equipment, plastic, chemical fiber, rubber, pharmaceutical, metallurgy, petrochemical, automobile manufacturing, ceramic glass and other fields .

　　單尼斯科

　　Dynisco

　　1952年，美籍華人李耀滋和李詩穎兄弟在美國波士頓創建了Dynisco公司，公司主要生產應變式壓力傳感器，后來生產生產熔體壓力傳感器產品主要應用于化纖、橡塑行業。

　　2011年僅28歲的吳浩先生將一手創建的上海皓鷹測控技術有限公司出售給Dynisco的母集団上市美資Roper集團，吳浩先生被Roper集團返聘擔任Dynisco中國公司總裁并且創建了Dynisco中國工廠。

　　In 1952, the Chinese-American brothers Li Yaozi and Li Shiying founded the Dynisco Company in Boston, USA. The company mainly produces strain gauge pressure sensors, and later produced melt pressure sensor products mainly used in the chemical fiber, rubber and plastic industries.In 2011, Mr. Wu Hao, who was only 28 years old, sold Shanghai Haoying Measurement and Control Technology Co., Ltd. to Dynisco's parent company and listed the American-owned Roper Group. Mr. Wu Hao was rehired by Roper Group as the president of Dynisco China and founded Dynisco China Factory. .

　　杰弗倫

　　GEFRAN

　　GEFRAN（杰弗倫）是在意大利米蘭上市的專業生產控制器、壓力傳感器、位移傳感器、熔體壓力傳感器及工業自動化系統的家族企業。

　　1969年Gefran第一個車間在意大利普羅瓦利奧(布雷西亞省)建立，生產用于制造塑料的機器的電動面板；20世紀70年代開始在意大利和國際市場上推出了Adamello控制器，后來被稱為1000型，為該行業樹立了基準；20世紀80年代開始收購熔體壓力傳感器公司美國ISI，公司將生產范圍擴大到包括熔體壓力傳感器在內。

　　GEFRAN is a family-owned company specializing in the production of controllers, pressure sensors, displacement sensors, melt pressure sensors and industrial automation systems listed in Milan, Italy.In 1969 Gefran's first workshop was established in Provallio (province of Brescia), Italy, to produce electric panels for machines used to make plastics; the 1970s began with the introduction of the Adamello controller on the Italian and international markets, later called For the Model 1000, it set the benchmark for the industry; in the 1980s, the acquisition of the melt pressure sensor company American ISI began, and the company expanded its production to include melt pressure sensors.

　　日本RKC生產的熔體壓力傳感器，銷售量以及應用并不多；還有比如美國GP50、英國Terwin基本上等銷售量以及應用也不多。

　　除此之外，其他國外熔體壓力傳感器品牌全部為貿易型企業，比如德國的格諾斯GneuB都是貿易型公司，并不自己生產熔體壓力傳感器，跟中國國內很多的貿易公司一樣，代工制造，沒有任何核心技術和專業競爭力。
