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.


We are proud of our products and solutions, but they really reveal their true colors when used by our customers. Whether digitalized, automated or electrified – mobile machines repeatedly delight with new innovations, in particular in terms of their user-friendliness, reliability and ability to integrate into work processes. Thanks to our customers, we are delighted to present a small selection here.


Our objective is to support our customers in all aspects concerning the digitalization, automation and electrification of their mobile machines. We consider the entire machine lifecycle and develop our STW product and service portfolio in alignment with this lifecycle. The ECO system, an open and holistic approach, facilitates the cross-topic integration of STW solutions. Furthermore, our product approach facilitates functional expansion through partner offers and hybrid, integrated products based on our system module.


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.
