Who we are

STS has stood for outstanding pressure measurement technology since 1987. What began as a specialist for piezoresistive pressure sensors is now an internationally active family business with headquarters in Sirnach, Switzerland. With over 130 qualified employees, we develop and manufacture high-precision and durable sensor solutions - individually tailored to demanding applications in the process industry.

Our product portfolio includes sensors for measuring pressure, level, temperature and flow. In our innovation factory in Sirnach, we create customer-specific solutions that combine technical precision with many years of experience and consistent customer focus. The sensors are developed, calibrated and tested here - for reliable use under the toughest conditions.

Since 2022, an additional development and production site in the USA has complemented our global structure. Together with subsidiaries in Germany, Italy, France, the UK, China and the USA, STS is now internationally positioned - and at the same time close to our customers' applications. Because at STS, every solution begins with a clear understanding of the respective requirements.

Our milestones

The beginnings

1987

STS was founded at Büfelderstrasse 1 in Sirnach, Switzerland, with one telephone, four desks and countless ideas. The bold visionaries behind this company were Alfred Schneider, Hans-Peter Müller, Jens Bomholt and Michael von Ritter. In the early days, the team devoted themselves exclusively to research and often cycled to work.

A stroke of luck

1989

Sometimes luck favors the brave. The financial restructuring of a competitor enabled STS to acquire used machines at a good price and secure a major order from a leading German excavator manufacturer.

Broadening horizons

With this important economic support, STS was able to expand its radius of action, establish contacts, secure loans and find strategic locations. Production in Sirnach in Switzerland flourished and the trucks were full of products. In 1991, J. Bomholt left the company and L. Séchy became the new CEO.
