KELLER AG für Druckmesstechnik, Global headquarters located in Switzerland, is Europe’s leading manufacturer of isolated pressure transducers and transmitters. The company overall has a 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 piezo-resistive 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 KELLER AG offers wide range of products that includes digital manometers, level probes, data loggers, remote transmission units & pressure calibrators and Digital display equipment. The application areas for pressure transducers are just as broad as the product range. KELLER special sensors, such as modular pressure catheters and other miniature transducers, are especially popular among researchers.
