With the pressure switch family, we offer modules for the measurement of pneumatic and hydraulic pressures which provide the ideal solution for every requirement. The pressure connection, pressure range, electrical connection and output signal can be combined in almost any way. The transmitters from the pressure switch family bear an E1 test mark. The P01 family is intended for applications with a switching function. Here the pressure transmitters have been developed for use in adverse ambient conditions. The mechanical and electronic characteristics of the pressure switch series have been especially designed for the purpose; in the same way, value is placed on high resistance to aggressive media. In addition to the numerous combination possibilities, we also offer the possibility of producing and supplying OEM versions. Silicon measurement cells are used for low pressure ranges from 0.25 bar to 4.0 bar. These can be used at media temperatures from −40 °C to +85 °C. For pressure ranges from 10 bar to 1200 bar, which are frequently required for use in mobile machines, welded stainless steel measurement cells are used which are basically suitable for media temperatures from −40 °C to +150 °C. Depending on the type of measurement cell and the material coming into contact with the media, the Pressure Transmitters pressure switch are resistant to aggressive or non-aggressive gases and liquids. On request, versions in 316L design for use in hydrogen pressure measurements are available.


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.
