The mechanical and electronic characteristics of the M01 series from Sensor-Technik Wiedemann (STW) have been especially designed for applications in adverse ambient conditions; in the same way value is placed on high resistance to aggressive media. Furthermore, the modular principle of the M01 series permits a large number of combinations of pressure connection, pressure range, electrical output signal and electrical connection, meaning that the right pressure transmitter can be found for almost any application. Over and above this, we also offer the possibility of producing and supplying OEM versions. For pressure ranges from 10 bar to 2000 bar, which are frequently required for use on mobile machines, welded stainless steel measurement cells are used which are 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 M01 Pressure Transmitters are resistant to aggressive or non-aggressive gases and liquids. On request, versions in 316L design for use in hydrogen pressure measurements are available. In addition to CE and UL certificates, every product in the M01 series with a 1.4542 stainless steel measurement cell possesses an E1 approval verifying its suitability for use in vehicles.


The Pressure Transmitter M01 has been developed especially for use in commercial vehicles and mobile machines. It is based on a thin-film measurement cell made from stainless steel which is welded together with the pressure sensor and thus guarantees high media compatibility.
