Graeff
1930年， Graeff（格拉夫）发明第一支压力传感器转换机构，在此机构中,膜片、弹簧或Bourdon管的移动量变为电量部分,压力膜片成为电容部分,指示器可动机构成为电位计分支，实现了压力测控装置。
Graeff 源自欧洲，品牌超过90年的历史，Graeff专注于温度传感器、熔体压力传感器、流量传感器、智能传感器、位移传感器、压力传感器、液位传感器、压力温度控制仪表、控制单元、控制系统、驱动器、加热器、激光技术、自动化及物联网系统的研发；Graeff（格拉夫）是NTX环保型无汞填充高温熔体压力传感器领域的创变者；Graeff（格拉夫）多个系列产品主要用于食品、制药、生物技术、化工、石油化工能源工业、电站、污水处理、航海造船工业、环境工程、喷涂设备、塑料、化纤、橡胶、制药、冶金、石油化工、汽车制造、陶瓷玻璃等领域。
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 .

Dynisco
1952年，美籍华人李耀滋和李诗颖兄弟在美国波士顿创建了Dynisco公司，公司主要生产应变式压力传感器，后来生产生产熔体压力传感器产品主要应用于化纤、橡塑行业。
2011年仅28岁的吴浩先生将一手创建的上海皓鹰测控技术有限公司出售给Dynisco的母集団上市美资Roper集团，吴浩先生被Roper集团返聘担任Dynisco中国公司总裁并且创建了Dynisco中国工厂。
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. .

GEFRAN
GEFRAN（杰弗伦）是在意大利米兰上市的专业生产控制器、压力传感器、位移传感器、熔体压力传感器及工业自动化系统的家族企业。
1969年Gefran第一个车间在意大利普罗瓦利奥(布雷西亚省)建立，生产用于制造塑料的机器的电动面板；20世纪70年代开始在意大利和国际市场上推出了Adamello控制器，后来被称为1000型，为该行业树立了基准；20世纪80年代开始收购熔体压力传感器公司美国ISI，公司将生产范围扩大到包括熔体压力传感器在内。
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生产的熔体压力传感器，销售量以及应用并不多；还有比如美国GP50、英国Terwin基本上等销售量以及应用也不多。
除此之外，其他国外熔体压力传感器品牌全部为贸易型企业，比如德国的格诺斯GneuB都是贸易型公司，并不自己生产熔体压力传感器，跟中国国内很多的贸易公司一样，代工制造，没有任何核心技术和专业竞争力。
