Who we are

KELLER Pressure – Your Swiss Pressure Sensing Specialist

- Europe’s leading manufacturer of isolated pressure transducers and transmitters

- Pressure ranges from 5 mbar to 2000 bar

- High volumes at low prices, great flexibility, highest accuracies

- Production of more than one million pressure transducers and transmitters per year

- KELLER is certified according to ISO 9001

KELLER Pressure, headquartered in Winterthur (Switzerland), is Europe’s leading manufacturer of isolated pressure transducers and transmitters. The company, which has a global workforce of around 450 employees, was founded in 1974 by Hannes W. Keller, a graduate in physics and the inventor of the integrated silicon measuring cell. The entire value creation, from production of the individual parts and calibration of the sensor through to the final inspection of the finished products, takes place at the headquarters in Winterthur. All KELLER products are therefore “Made in Switzerland”.

KELLER piezoresistive pressure sensors have impressively high precision and pressure ranges from 5 mbar to 2000 bar. In addition to more than 500 standard products, the company also develops and produces numerous customised solutions. Using state-of-the-art, automated manufacturing processes, large runs of industrial OEM transducers as well as special design versions in very small quantities are produced in more than 35 highly-specialised machining islands, resulting in more than one million pressure transducers and transmitters per year. The high quantities allow to keep prices low despite complex production processes and stringent quality requirements.

The KELLER product range includes digital manometers, level probes, data loggers, remote transmission units and pressure calibrators. Digital display equipment completes the wide range. The application areas for KELLER’s pressure transducers are just as broad as KELLERs product range. For example, they regulate the internal cabin pressure in aircrafts, ensure the smooth switchover from natural gas to petrol in hybrid vehicles and are used as reference sensors in laboratory technology. KELLER special sensors, such as modular pressure catheters and other miniature transducers, are especially popular among researchers.

KELLER is certified to ISO 9001. The traceability of the measurement variables to national standards is therefore ensured.

Our values

Collaboration

– We put a strong focus on our customers and their needs. Collaboration is key to meet individual application requirements and provide effective solutions. More than 70% of our sensors are custom products.

Advancement

– We believe in our technology and push the boundaries of what is possible in terms of precision and operating conditions. Piezoresistive pressure sensors are used in almost every thinkable environment and can reach accuracies of 0.01% full-scale.

Mutual Support

– We emphasize a culture of open communication, honesty and mutual support. We are convinced that by conjoining the knowledge of different internal teams and by working closely together with our suppliers, distributors and customers we can all advance and prosper.

Courage

– We are not afraid of taking a calculated risk if the circumstances are right. Many of our most innovative and successful products started out as a daring project.

Independence

– We are proud to be an independent Swiss family enterprise. KELLER is not obligated to any bank or investor and our entire value creation takes place in Switzerland.
