Our parent, Keller AG für Druckmesstechnik, began life in a loft above a car dealership in the small town of Winterthur, Switzerland, near Zurich. Lack of money spawned creativity and improvisation. Success first came as a supplier of sensors to established OEMs, who already had a market for their products. Many of those original customers are still with us today. Nowadays, with the advent of inexpensive, miniaturized microprocessors, Keller continues to advance the state-of-the-art in fully packaged pressure transmitters, 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.

At Keller, providing our customers with superior value is a way of life. Contact us today, toll-free at 877-253-5537 or e-mail to us at sales@kelleramerica.com.
