　　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 450 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 für Druckmesstechnik總部位于瑞士溫特圖爾，是歐洲隔離壓力傳感器和變送器制造商。該公司在全球擁有約450名員工，1974年由物理畢業生、集成硅測量單元發明家漢內斯·W·凱勒（Hannes W.Keller）創立。整個價值創造，從單個零件的生產、傳感器的校準到成品的檢驗，都發生在溫特圖爾的總部。因此，凱勒公司的所有產品都是“瑞士制造”。

　　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.

　　KELLER AG壓阻式壓力傳感器具有高的精度，壓力范圍從5毫巴到2000巴。除了500多種標準產品外，該公司還開發和生產多種定制解決方案。采用先進的自動化制造工藝，在超過35個高度化的加工島上生產大量的工業OEM傳感器以及非常小數量的特殊設計版本，每年產生超過100萬個壓力傳感器和變送器。盡管生產工藝復雜，質量要求嚴格，但數量多意味著我們可以保持低價格。

　　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.

　　凱勒公司的產品范圍包括數字壓力計、液位探頭、數據記錄器、遠程傳輸裝置和壓力校準器。數字顯示設備使我們的產品范圍更廣。我們的壓力傳感器的應用領域和我們的產品范圍一樣廣泛。例如，調節飛機艙內壓力，保證混合動力汽車從天然氣到汽油的平穩切換，作為實驗室技術中的參考傳感器。凱勒特殊傳感器，如模塊化壓力導管和其他微型傳感器，在研究人員中特別受歡迎。
