For pressure switching tasks in pneumatic and hydraulic systems, we offer a modular pressure switch system that provides the right answer to every requirement. Pressure connection, pressure range, electrical connection and switching type can be combined in almost any way. The pressure switches have been developed for use in harsh ambient conditions and have the E1 test mark. The mechanical and electronic properties have been specified for this purpose. In addition to the numerous combination options, we also offer the design, manufacture and supply of OEM versions. Silicon measuring cells are used for lower pressure ranges, up to 7 bar. These can be used at media temperatures from -40 °C to +85 °C. For high pressure ranges, from 10 bar to 2000 bar, which are often required for use in mobile machinery, welded stainless steel measuring cells are used. These are generally suitable for media temperatures from -40 °C to +150 °C. Depending on the choice of measuring cell and the material in contact with the medium, the pressure switches can be used with aggressive gases and liquids. Versions in 316L stainless steel for use with hydrogen are also available on request.


While we are proud of our products and solutions, it is through our customers’ applications that the power in the innovative technology is unleashed.  Whether fully networked, highly automated, or operating fully autonomously, an effective mobile machine represents first class interdisciplinary engineering. Robust and safe integration into the system architecture of the machine and its work processes, while remaining convenient and user friendly, is the main focus. With thanks to our customers, here we would like to present a small selection of example applications.



We support our customers as a partner for the digitization and automation of mobile machines and the related work processes. Our comprehensive and highly interoperable STW modular system of high quality sensing, control and software products ensures a problem free integration in the final application.


As experts in all aspects of functional safety, we offer services in high level automation in the field of mobile machines, including autonomous functions and driving. Our STW ecosystem includes a comprehensive partner network of system integrators and distributors to ensure an optimal solution for every application, worldwide.


We accompany our customers from the start whenever the E/E system in mobile machines is concerned. For this purpose, we develop solutions to support the entire machine lifecycle. We offer our competence, our services, our products and the associated tools in the individual phases in order to make an efficient and continuous contribution towards the success of the machine. 



The STW "ECO System" is characterized through the integration of systems and products which transcend the borders between solution areas. Our partners also supplement the STW product and services portfolio for the benefit of our customers. The open nature of the product portfolio permits easy integration of the products into third-party systems or the supplementation of our system through further products by third party providers.
