STS

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.
