瑞士KELLER，这个名字在世界的压力测量史中也占据了一席之地，这个名字始终与压阻式压力测量技术的发展息息相关。 

在二十世纪60年代，KELLER公司的创立者H.W.KELLER在位于明尼阿波利斯(Minneapolis)的霍尼韦尔(honeywell)研究中心开发了世界上第一个内嵌式硅测量元件，并在美国为该内嵌式硅测量元件的制造方法申请了专利。Products of National Semiconductor, Foxboro,和Honeywell等公司直接或间接以该专利为基础发展了自己的技术。

到了二十世纪70年代初，KELLER先生开发出世界上第一个铁外壳的扩散硅压力变送器，在那之后不久，H.W.KELLER先生建立了自己的公司－KELLER AG für Druckmesstechnik。从一个小公司起步，KELLER AG现在已经成长为世界压力测量领域的领导者。从我们的10系列OEM芯体，到完整而专业的压力变送器产品线，KELLER AG始终保持在开发与创新的最前沿。随着低成本，小型化的微处理器的出现，KELLER利用艺术级的工艺实现了几年前还远远达不到的精度。目前我们的压力传感器和压力变送器的年产量已经超过1,250,000台。

KELLER，您可靠的压力测量合作伙伴。

KELLER AG für Druckmesstechnik, headquartered in Winterthur (Switzerland), is Europe’s leading manufacturer of isolated pressure transducers and transmitters. The company, which has a global workforce of around 400 employees, was founded in 1974 by Hannes W. Keller, a graduate in physics and the inventor of the integrated silicon measuring cell. The entire value creation, from production of the individual parts and calibration of the sensor through to the final inspection of the finished products, takes place at the headquarters in Winterthur. All KELLER AG products are therefore “Made in Switzerland”.

KELLER AG piezoresistive pressure sensors have impressively high precision and pressure ranges from 5 mbar to 2000 bar. In addition to more than 500 standard products, the company also develops and produces numerous customised solutions. Using state-of-the-art, automated manufacturing processes, large runs of industrial OEM transducers as well as special design versions in very small quantities are produced in more than 35 highly-specialised machining islands, resulting in more than one million pressure transducers and transmitters per year. The high quantities mean that we can keep prices low despite complex production processes and stringent quality requirements.

The KELLER AG product range includes digital manometers, level probes, data loggers, remote transmission units and pressure calibrators. Digital display equipment completes our wide range. The application areas for our pressure transducers are just as broad as our product range. For example, they regulate the internal cabin pressure in aircrafts, ensure the smooth switchover from natural gas to petrol in hybrid vehicles and are used as reference sensors in laboratory technology. KELLER special sensors, such as modular pressure catheters and other miniature transducers, are especially popular among researchers.

KELLER AG für Druckmesstechnik, including KELLER Ges. für Druckmesstechnik mbH Jestetten, is certified to ISO 9001:2008. The traceability of the measurement variables to national standards is therefore ensured.
