About KELLER AMERICA
The name Keller has earned its place in the History of Pressure Measurement, as it is closely connected with the development of the piezoresistive technology.
In the 60's, company founder H. W. Keller developed the first integrated silicon pressure measuring cell at the Honeywell Research Center in Minneapolis. He also patented the integrated production method of this silicon cell in the United States. Products of National Semiconductor, Foxboro, and Honeywell have been directly or indirectly developed on the basis of this work.
At the beginning of the 1970's, Mr. Keller developed the first piezoresistive pressure transducer with a steel housing. Shortly thereafter, in 1975, H.W. Keller founded his own company, Keller AG für Druckmesstechnik. From humble beginnings, Keller AG has grown to a worldwide leader in pressure measurement solutions. From the advent of the Series 10 OEM pressure transducer, to the complete lineup of specialty pressure transmitters, Keller AG remains at the leading edge of development and innovation. With the advent of inexpensive, miniaturized microprocessors, Keller continues to advance the state-of-the-art with Total Error Band performance not possible just a few short years ago. Annual sensor production, combining OEMs with our own transmitter products, now exceeds 1 million pieces.
