KELLER PRESSURE
A market leader in the production of isolated pressure transducers and transmitters
KELLER Pressure was established in 1974 by Hannes W. Keller, the inventor of the integrated silicon measuring cell. Today, his sons Tobias and Michael Keller run the business. The company is wholly family-owned and employs 480 staff.
KELLER feels a strong connection to its home of Switzerland. Its headquarters are where the value is added and where most of our employees work. As a result, all KELLER products bear the quality seal «Made in Switzerland» and embody the Swiss values of quality, functionality and reliability.
KELLER Druckmesstechnik AG, including KELLER Gesellschaft für Druckmesstechnik mbH in Jestetten, is certified to ISO 9001. This means that our measured values can be fully traced to national standards.
