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”.
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.
