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 Druckmesstechnik (KELLER Pressure Measurement Technology). From humble beginnings, KELLER 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 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.
