Om Keller Sweden AB
KELLER AG für Druckmesstechnik, headquartered in Winterthur (Switzerland), is Europe’s leading manufacturer of isolated pressure transducers and transmitters.
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.
More about the company
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's recognition symbol is the sea gull. The gull stands like the pigeon in the Trinity picture as a symbol for philosophy, for the love towards wisdom and truth. The owner of the company lives by the motto of his wise ancestors:
Son, you are free if you do not have to suck up to asses.
You are rich when you can tell them that.
You are wise if you do not have to tell them anymore.
It's the philosophy embodied in several articles that have made KELLER to the undisputed leader in Pressure Metrology. It is worthwhile to reflect about it.
