KELLER Pressure GmbH
About us
KELLER Pressure Measurement Technology was founded in 1974 by Hannes W. Keller, the inventor of the integrated silicon pressure cell. Today, his two sons, Tobias and Michael Keller, manage the business. The company is wholly family-owned and employs 480 people. KELLER Pressure is committed to its Swiss location. All value creation takes place at the headquarters, where the majority of employees also work. All KELLER Pressure products therefore bear the "Swiss Made" seal of quality and embody the Swiss understanding of quality, functionality, and reliability. KELLER Pressure manufactures sensors for pressure measurement technology with the highest precision. KELLER Pressure Measurement Technology AG, including KELLER Pressure GmbH Jestetten, is ISO 9001 certified.

The new LEO-Ultimate pressure gauge
The new generation of digital pressure gauges with the highest precision.
Hydrogen – fuel of the future, but how can the pressure be reliably measured?
Materials that come into contact with hydrogen must therefore meet particularly stringent requirements. This fact is what gives pressure transmitters manufacturers one of our biggest collective headaches.
