• Compact and robust design for use in harsh environments
  • Pressure transducers for
    • Mobile hydraulics
    • Hydrogen and other aggressive media
    • ATEX and industrial applications
    • Cylinder pressure measurement
    • Special applications with very high environmental requirements
  • Maximum flexibility facilitated through modular structure; adaptation and individualization possible
  • Developed for OEM requirements, also in connection with functional safety requirements

With the pressure sensor family, we offer a modular system for the measurement of pneumatic and hydraulic pressures, which provides the right solution for every requirement. Pressure connection, pressure range, electrical connection and output signal can be combined in almost any way. All pressure sensors feature an E1 certification mark and have been developed for use in harsh ambient conditions and the extremely high requirements common in hydraulics or also in the braking system of mobile machines. In addition to the numerous combination possibilities, we also offer the possibility to manufacture and supply OEM solutions. 

For low pressure ranges, silicon measurement cells are used. For high pressures, which are often required for use in mobile machines, welded stainless steel measurement cells are used. Depending on the type of measurement cell and the material in contact with the medium, the pressure sensors are resistant to aggressive or non-aggressive gases and liquids. Versions in 316L design for use with hydrogen, CNG and LPG are also available on request. 

In addition to the standard M01 version, the pressure sensors are also available in the F02 Safety variant for safety-critical applications that require an appropriate Performance Level.

The pressure sensor variant was specifically developed for applications involving hydrogen as well as in in ATEX protected environments.

The pressure sensor was developed for high performance measurements under high temperature conditions, as typical in cylinder pressure applications on combustion engines.


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.
